Description
Description — RADIAC
The Radiation Detection, Indication and Computation (RADIAC) Program is responsible for the acquisition of new equipment needed to replace obsolete and unsupportable instruments to maintain legally compliant radiological operations. The equipment includes radiation monitoring instruments that detect and measure ionizing radiation used on all Navy, Coast Guard and Military Sealift Command vessels, and at every Navy shore installation, in order to ensure the safety of personnel, continuity of operations in radiological or nuclear contingencies, and protection of the environment. [P40A / M2100 - Survey Meters]: M2100. Radiation survey meters, required by 10 CFR 20 and the Navy's mission, are used to detect, measure and monitor radiation levels in support of operations involving radioactive materials. Navy operations associated with radioactive materials include operation of nuclear reactors, maintenance on radioactive systems or components, testing of components for structural integrity (X-ray), research, and medical diagnostics and treatment. Additionally, radiation survey meters are used to search for, locate and intercept radioactive material, and in responding to casualties involving radioactive materials. Where radiation survey meters are used to support operations involving radioactive material, they provide real-time information used to control personnel radiation exposure and to identify and control the spread of radioactivity. When used to search for radioactive material, they provide an extremely reliable method of identifying radioactive material while minimizing the risk to personnel conducting these operations. [P40A / Radiological Detection System]: M2100, Radiological Detection System (RDS): This is a basic RADIAC instrument used in Consequence Management and Occupational Safety and Health applications by all ships (U.S. Navy, U.S. Coast Guard and Military Sealift Command) and shore commands. It is used to survey for radioactive surface contamination pursuant to nuclear plant operations or nuclear plant maintenance; following medical procedures involving radioactive isotopes; or casualties and events that release radioactivity into the environment such as after a nuclear reactor accident or the use of weapons involving nuclear devices or radioactivity. It is also used to perform surveys for various types of radiation in order to monitor environmental conditions in areas and spaces immediately adjacent to where radioactive material is stored or used during routine operations; where nuclear plant operations occur; and where radioisotopes are used for maintenance, such as during industrial radiography operations. The RDS consists of a Control Unit and a suite of probes that survey for different types of radioactivity (Alpha, Beta, Gamma, Neutron). Also part of the procurement will be various types of connecting cables; carrying cases; telescoping handles; and three specialty probes. The Control Unit is necessary for all applications while the probes are used for different applications. That means the Control Unit will have the highest procurement objective and the probes and ancillary equipment will be bought in varying quantities. This instrument will replace the Navy's 30-year-old IM-265/PDQ Multi-Function RADIAC Control Unit and its probes. The RDS is being developed by the Joint Product Leader for Radiological and Nuclear Defense (JPdL-RND) in order that the Army, Navy, Marine Corps, Air Force (and some NATO allies) will all have a Joint instrument that will enable interoperability and surge support of assets from all the components to forward deployed units in a theater of operations where a radiological event arises. [P40A / Near Background Survey Meter Data]: M2100, Near Background Survey Meter Data: Test reports, Technical Manuals, Technical Repair Standards. [P40A / Near Background Survey Meter]: M2100, Near Background Survey Meter: This is a specialized RADIAC instrument used in an Occupational Safety application on forward-deployed nuclear powered vessels. It is used to survey areas for radiation levels slightly above background levels. Surveys ensure foreign nationals do not receive radiation doses from sources associated with the nuclear propulsion plant that are distinguishable from natural background. Changes in radiation level must be measured in less than two seconds. Currently, foreign nationals are not permitted in areas which may contain elevated radiation levels. Two devices are currently in use; both are obsolete with the vendor discontinuing support in the near future. The new meter combines the functionality of both instruments. [P40A / M2100 NWCF Contract Fee]: M1200 NWCF Contract Service Fee: The contract office for hardware acquisitions is a Navy Working Capital Fund (NWCF) activity that charges a set fee for each contract award and modification. The applicable fee(s) for a given year are applied to the total value of the Cost Code hardware acquisitions. Fees vary from year to year. [P40A / M2200 - Dosimetry]: M2200. Dosimetry consists of radiation sensitive materials that are used for detecting and measuring an individual's exposure to ionizing radiation and to aid in minimizing this exposure. Dosimetry is required to be worn by personnel who work with sources of radioactivity or by personnel responding to casualties involving radioactivity. Most dosimeters are small devices that are worn on the belt, on a lanyard around the neck or attached to a shirt. Some dosimeters provide direct readout enabling the wearer to monitor and control radiation exposure. Other types of dosimeters must be removed from the wearer to be evaluated in special dosimeter readers that extract the recorded radiation exposure value from the dosimeter. Radiation exposure measured by dosimetry is recorded in individual medical records when formal tracking of the radiation exposure is required. In accordance with 10 CFR 20, dosimetry is required to be worn by personnel who work with sources of radioactivity. In the Navy this includes personnel in the Nuclear Propulsion, Nuclear Weapons, and Medical and Radiological Affairs Support programs. In these programs radiation exposure is measured by dosimetry and recorded in individual medical records for tracking purposes. Dosimetry is also worn by personnel responding to casualties involving radioactivity to control their exposure within acceptable levels. [P40A / DT-702 Card Holder]: M2200, DT-702 Card: The DT-702 card contains radiation sensitive material and is worn by personnel to monitor exposure to radiation. Elements 1, 2, and 3 are sensitive to photons (gamma-ray and x-ray) and betas and Element 4 is sensitive to photons, betas, and neutrons. DT-702 Card Holder: The DT-702 Holder is used to hold and protect the DT-702 card during use. It consists of a hard plastic case with both belt and lanyard attachments. These attachments allow the DT-702 Holder (with DT-702 Card inserted) to be easily attached to the wearer during use. The holder contains four filters corresponding to the four elements. Positions 1, 2, 3, and 4 have copper, plastic, mylar, and tin filters, respectively. Positions 1, 2, and 4 also have the holder itself providing shielding. All positions have different density thickness to help discriminate different types of radiation and energies to provide an accurate dose of record when processed through the Dose Program. [P40A / Extremity Dosimeter]: M2200, Extremity Dosimeter: An extremity dosimeter is used to measure concentrated exposure to the hands when a radiation worker is reaching into a glove box or medical personnel are performing fluoroscopy tasks. This item is composed of three inexpensive pieces: 1) a plastic ring (~$2) to wear on a finger; 2) a dosimeter (~$36) that measures exposure; and 3) a cap (~$3) that secures the dosimeter to the ring. The cap is made to a specific thickness depending on the type of radiation the dosimeter is intended to measure. These items will be procured in quantities of 3,000 each. An average unit cost for the three items is used and all 9,000 components are shown on this one Cost Element. [P40A / Accident Dosimeter]: M2200, Accident Dosimeter: The Accident Dosimeter is a passive type of nuclear dosimeter capable of detecting and recording fast neutron radiation exposures. These dosimeters are used to determine radiation dose to the crew in the event of an accident affecting operation of a nuclear reactor. These dosimeters are fastened near or adjacent to reactor compartments on all Navy submarines and carriers. [P40A / Accident Dosimeter Data & Training]: M2200, Accident Dosimeter Data & Training: The Naval Dosimetry Center staff will be trained on how to evaluate the dosimeter. The vendor will supply Technical Manuals, Technical Repair Standards and Standard Calibration Procedure documentation in order for the detectors purchased to be maintained by Navy Radiation Calibration Laboratories. [P40A / Battlefield Dosimeter]: M2200, Battlefield Dosimeter: A dosimeter designed for use during nuclear or radiological events involving high energy gamma and neutron irradiation. An "event" can be a nuclear reactor accident, such as the Fukushima disaster in 2011, or an attack on, e.g., a Carrier Strike Group using a nuclear or radiological (dirty bomb) weapon. The concept of operations for such a dosimeter is that it is issued at MOP (Military Operational Posture) III to allow the commander to manage the exposure received by members of recovery teams who would be deployed in order to maintain continuity of operations. It is also used to perform triage on casualties, allowing medical personnel to most effectively allocate their resources. [P40A / Battlefield Dosimeter Cases]: M2200, Battlefield Dosimeter Cases: The Battlefield Dosimeter will spend much of its time aboard ships stored in Damage Control Lockers. The instrument will also have to be shipped to and from a RADIAC Calibration Laboratory to undergo periodic calibrations. Because allowances for the instruments on the various ship classes range from 12 on an LCS to 700 each on a CVN, cases configured to hold different quantities (25, 50, 100) will be procured to afford the necessary protection for storage and shipping while maximizing shipboard storage space efficiency. [P40A / M2200 NWCF Contract Service Fee]: M2200 NWCF Contract Service Fee: The contract officer for hardware acquisitions is a Navy Working Capital Fund (NWCF) activity that charges a set fee for each contract award and modification. The applicable fee(s) for a given year are applied to the total value of the Cost Code hardware acquisitions. Fees vary from year to year. [P40A / Electronic Personnel Dosimeter]: M2200, Electronic Personnel Dosimeter (EPD): The Navy's current EPD has been fielded since 2007. However, the current EPD is no longer manufactured. EPD units ready for issue will be depleted 25% by 2024 and will soon drop to zero. To ensure continued EPD use, the Navy's next EPD procurement of approximately 34,000 EPDs is planned. Therefore, as use and availability of the current EPD ramps down, use and availability of the next EPD will ramp up. [P40A / Navy Occupational Dosimeter System]: M2200, Navy Occupational Dosimeter System (NODS): The DT-702/PD system was designed in the 1990s and fielded in 2000 and is approaching the end of its useful life due to obsolete parts and because the vendor has not successfully addressed several other obsolescence issues. The system will not be logistically supportable after 2030. The NODS will replace it while providing improved dosimetry capabilities and the ability to consolidate legacy records currently spread across several databases. NODS will improve the Navy's capability to detect, transmit, record, and report the dose received by Navy radiation workers at occupational and accident levels, enhancing the health and safety of personnel. [P40A / M2400 - Other RADIAC]: M2400. Other RADIAC. The RADIAC Program fields 70 different families of instruments, consisting of a total of almost 43,000 instruments and 400,000 dosimeters. Those families that fall into similar functionality have been grouped here into the M2100, M2200, M2500 and M2600 Cost Codes. The M2400 Cost Code consists of instruments that have specialized functions that only they perform, and therefore would require an unmanageable and meaningless number of additional Cost Codes if each were addressed individually. In the context of the family metaphor used here, these instruments are no less important but are orphans in the sense there are not many of similar functionality with which they could be grouped. This Cost Code also supports replenishment of Ready for Issue (RFI) stocks when instruments in any Cost Code fall below stock levels sufficient to meet quarterly demand. This Cost Element (Spares) is a Continuing element that varies year-to-year based on emergent requirements and the quantity and unit cost of the item(s) being replenished. [P40A / Spares]: M2400, Spares: Purchase of additional quantities of existing models of RADIACs to replenish or supplement stocks of items due to minor increases in program allowances, inventory losses, or due to assets being beyond economical repair. [P40A / M2500 - Air Sampling Systems]: M2500. Monitoring for airborne radioactivity is done to detect leaks from nuclear reactors or associated systems to ensure that radioactivity is not inadvertently released to the environment from these operations. Additionally, monitoring for airborne radioactivity is performed during maintenance on radioactive components or during events that might cause radioactivity to be released to the air. Monitoring for airborne radioactivity is normally done by drawing air across filter paper to collect airborne radioactive particles. This filter paper is then evaluated by radiation detectors and the concentration of airborne radioactivity is calculated. The types of airborne radioactivity monitoring systems include fixed systems and portable systems. Fixed systems sample air from pre-determined locations and normally include built-in radiation detectors for determining the airborne radioactivity concentration. Portable systems can be used to sample air at any desired location, but normally require the use of separate radiation detection instruments to measure the radioactive particles deposited on the filter paper to determine the airborne radioactivity concentration. [P40A / APD Ship Frames]: M2500, Air Particle Detector (APD), Ship, Frames: In accordance with the referenced standard, the currently fielded IM-239/WDQ frames and some specific components are Restored, which is defined in the reference as making the equipment ". . . conform to the current technical specifications for the item . . . and the restoration of the equipment's physical appearance to the manufacturer's original condition (like new)." The Government provides these units as Government Furnished Property (GFP) to the vendor building the IM-272/WDQ APD, into which they build and install modern components. [P40A / APD Ship]: M2500, Air Particle Detector, Ship: Airborne radioactivity monitoring system that is required for use on CVNs and all submarines. This system (IM-272A/WDQ) is a replacement for the existing IM-239/WDQ used on all Navy submarines and carriers. The IM-272A/WDQ incorporates significant technology enhancements that will reduce spurious false alarms and reduce operator maintenance. [P40A / APD Ship Conversion]: M2500, APD Ship Conversion: Under the new contract awarded in September 2019, 10 of the 30 IM-272/WDQ units procured in FY17 will be converted to the IM-272A/WDQ to enable them to be fielded. [P40A / APD Ship GFP Repair by Contractor]: M2500, Air Particle Detector, Ship GFP Repair by Contractor: The APD Ship utilizes GFP in its design. The Government prepares the GFP prior to shipment to the contractor. Certain pieces require additional repair work by the contractor. The Government will fund the contractor to repair GFP as needed in order to mitigate risks to cost and schedule. [P40A / M2500 NWCF Contract Service Fee]: M2500 NWCF Contract Service Fee: The contract officer for hardware acquisitions is a Navy Working Capital Fund (NWCF) activity that charges a set fee for each contract award and modification. The applicable fee(s) for a given year are applied to the total value of the Cost Code hardware acquisitions. Fees vary from year to year. [P40A / Battery Operated Air Samplers]: M2500, Battery Operated Air Samplers: Research and testing efforts to find a possible replacement for the HD-11510 are currently funded in RDT&E. The HD-11510 is a battery powered portable air article sampler used for radioiodine sampling by the Naval Nuclear Propulsion Program (NNPP). The HD-11510 has been fielded for over 15 years. The weight of the device at 38 pounds has been a long-standing complaint by the end user community and obsolescence issues have arisen in the past 5 years. Naval Surface Warfare Center Carderock Division (NSWCCD) is researching three possible replacements for the HD-11510. These COTS solutions will be tested at NSWCCD and the battery testing and certification is expected to be obtained for one of the three BPAPS acquired. [P40A / M2600 - Laboratory Test Equipment]: M2600. This Cost Code supports specialized equipment usually found in laboratories, hospitals and test facilities. This kind of equipment is distinct enough to warrant separating it for management purposes from the M2400 Cost Code. [P40A / Calibrators]: M2600, Calibrators: Calibrators (also known as irradiators) are the basic tool used to calibrate all Navy radiological detection equipment. They consist of a high energy radiological source (Cs-137) in a shielded container that is located in a specially constructed and shielded room, or "range." A technician places the instrument to be calibrated at a specific calibration point in the range and remotely operates the calibrator by raising the source out of its container so that the radiological source becomes exposed and it irradiates the instrument. The instrument's response to the radiation is measured so that it can be calibrated to specific tolerances. [P40A / Calibrator Initial Spare Parts, Installation & Training]: M2600, Calibrator Initial Spare Parts, Installation & Training: Initial spare parts and vendor training at each of the seven RADIAC Calibration Laboratories where the equipment will be installed. The vendor will ship and install the calibrators at each of the seven Navy RADIAC Calibration Laboratories. Costs in FY 2020 and FY2021 includes initial spare parts and training at various sites in addition to installation of three calibrators each year. [P40A / TS-4575/FDM Calibrator]: M2600, TS-4575/FDM Calibrator: This system will be used to calibrate the IM-276/PD and IM-276A/PD Battlefield Dosimeters. In 2021, two new units will be procured. In 2022, the unit procured in 2019 as an RDT&E article for testing and further development of the device will be back-fitted as necessary in order to convert it into an updated, operational unit. The calibrators will be fielded to a Navy RCL on each coast, and the third to the Pearl Harbor RCL. [P40A / TS-4575/FDM Parts & Training]: M2600, TS-4575/FDM Parts & Training: Initial spare parts and training of RADIAC calibration technicians at the seven Navy RCLs on its operation and preventive maintenance. [P40A / M2600 NWCF Contract Service Fee]: M2600 NWCF Contract Service Fee: The contract officer for hardware acquisitions is a Navy Working Capital Fund (NWCF) activity that charges a set fee for each contract award and modification. The applicable fee(s) for a given year are applied to the total value of the Cost Code hardware acquisitions. Fees vary from year to year. [P40A / Radiation Check Source Kits]: M2600, Radiation Check Source Kits: The Cesium-137 (Cs-137) source in the MX-12xxx/S source kit series has a 30-year life span and it's reaching end of life. These source kits are assigned to various NAVY users to source check their RADIAC prior to start of shift. [P40A / M2830 - Support - Production Engineering]: M2830, Production Engineering: Labor cost of the government and contractor personnel who prepare the acquisitions. [P40A / Production Engineering Carderock]: M2830, Production Engineering: Production Engineering Labor Cost in support of NAVSEA 09RD OPN procurements. Manpower requirements include Engineers, Health Physicists, Scientists and other critical subject matter experts in acquisition life cycle management. [P40A / M2830 NWCF Contract Service Fee]: M2830 NWCF Contract Service Fee: The contract officer for service contracts is a Navy Working Capital Fund (NWCF) activity that charges a set fee for each contract award and modification. The applicable fee for a given year is applied to the total value of the contract action. Fees vary from year to year. [P40A / Production Engineering In Service Engineering Agent]: M2830, Production Engineering In Service Engineering Agent (ISEA): Labor cost of the contractor Engineers, Logisticians, Technical Writer, Program Analyst, and Systems Analysts who help prepare the acquisitions.
Justification
Justification — RADIAC
Title 10 of the Code of Federal Regulations, Part 20 (10 CFR 20) requires RADIAC instruments be used to ensure the safety of personnel who work with or who are exposed to radioactive materials in their work. Additionally, the Navy's mission requires personnel and ships to have the ability to operate in radiological environments and the ability to identify and interdict radiological Weapons of Mass Destruction (WMD). Navy programs that require RADIAC instruments for Occupational Safety & Health (OSH) reasons under the provisions of 10 CFR 20 include Naval Nuclear Propulsion, Nuclear Weapons, Medical, and Radiological Affairs Support. Non-OSH programs include Radiological Defense, Consequence Management, Training, Technical (RADIAC calibration, shielding evaluation, research) and Radiological Search (maritime interdiction to locate or intercept WMD). The FY 2026 request was reduced by $.036 million for Advisory and Assistance Services to promote efficiencies and advance the policies of the Administration in alignment with Executive Order 14222, "Implementing the President's Department of Government Efficiency Cost Efficiency Initiative." $7M decrease between FY25 and FY26 due to price changes in the Navy Occupational Dosimeter Systems (NODS) and rephasing the Radiological Detection Systems (RDS) to support higher Navy priorities.
