STATEMENT OF WORK FOR DECOMMISSIONING FUNDING ESTIMATE FOR SNM-362 LICENSE AND

NIST ACCELERATOR FACILITIES.

Background:

The National Institute of Standards and Technology (NIST) has maintained a Broad Scope Type A Special Nuclear Materials License for the use of radioactive materials (both sealed and unsealed) for production and use of radioactive measurement standards since the facility was established in the early 1960s. The license includes byproduct material in any form with atomic numbers 3 to 83. It also maintains standards production and measurements laboratories for other Naturally Occurring and Accelerator Produced Radioactive Materials (NARM) materials including radium/radon standards formerly outside the scope of the Nuclear Regulatory Commission’s (NRC’s) definition of byproduct material.

License records indicate that since establishment of the NIST Gaithersburg Campus, licensed radioactive material work under the SNM-362 license or the predecessor licenses has been authorized in approximately 20 buildings, yet the bulk of the work has been in the radiation physics building. Approximately 200 rooms have been authorized for licensed material work since the Gaithersburg campus open, of which approximately 130 are in active use.

The NIST operated a 100 MeV linear accelerator for production of charged particle and neutron beams used for materials science and fundamental physics from the mid-1960s through the mid-1980s. NIST continues to operate additional accelerators of lower energy. The major components of the 100 MeV accelerator were removed and disposed of during the late 1980s and early 1990s; however residual activation remains in building walls and structural components along the beam paths. Dose rates on some accessible (unshielded) surfaces as measured with handheld ion chambers currently range up to 5 mR/hr. Most activated surfaces are less than 0.5 mR/hr.

In late 1993 a decommissioning funding analysis was prepared in accordance with Regulatory Guide 3.66, “Standard Format and Content of Financial Assurance Mechanisms Required for Decommissioning Under 10 CFR Parts 30, 40, 70, and 72” (Attachment 1), and Nuclear Regulation (Nureg) 1727, It was submitted to the NRC and approved. That study has not been updated to account for changes in decommissioning technologies or disposal costs. A new comparable study is required as part of the license renewal process to satisfy 10CFR 70.25 and NUREG 1757, “Consolidated Decommissioning Guidance”, vol. 3 appendix A. (NOTE Nureg 1727 has been superseded by Nureg 1757).

In 2009 a decommissioning study was developed as part of the license renewal process to satisfy 10CFR 70.25 and NUREG 1757, “Consolidated Decommissioning Guidance”, vol. 3 appendix A. (NOTE NUREG 1727 has been superseded by NUREG 1757).

Work Requirement:

The contractor shall provide all personnel and services for the following:

1. Review historic license documentation to assess the need for and plan scoping measurements throughout the NIST Gaithersburg Campus.

2. Perform sufficient and necessary confirmatory and scoping surveys, contamination checks, and sampling including, if necessary, removal of surface shielding and core boring, drainpipe sampling and duct work measurements to determine the extent and depth profile of residual activation or contamination throughout the facility. (Sampling, core boring, or opening of mechanical systems shall be performed with care to assure no structural damage to the facility or prolonged removal from service. All surfaces and systems shall be restored following sampling.)

3. Report the estimates of the magnitude, isotopic composition, and distribution of the activity throughout the accelerator facility.

4. Report estimates of the magnitude, isotopic composition, and distribution of long-lived contamination throughout the radioactive materials laboratories, plumbing, or ventilation systems that would require removal for decommissioning.

5. Determine the extent of material removal or demolition required to satisfy the decommissioning release criteria of less than 25 millirem per year to the critical group. (In the report the contractor must define the basis of critical group i.e., they must identify utilization activities of the critical group).

6. Provide an initial characterization plan and monitoring requirements for the period prior to decommissioning and estimate of the cost for performing the monitoring.

7. Provide the scope, initial plan, and description of processes or activities required to perform the decommissioning of each of the major sections or operations of the facility.

8. Provide a written cost estimate for performing the required demolition or removal. Including engineering costs, equipment and material requirements and costs, labor requirements and costs, and contractor overhead.

9. Provide a written description of monitoring requirements during decommissioning processes and an estimate of the resources and costs for performing that monitoring.

10. Provide a written estimate of waste disposal requirements (volumes, mass, activities and forms) and estimate of costs.

11. Provide a written description and scope for performing the final status survey operations and an estimate of resources and cost.

12. Provide a basis for estimating annual escalation of the decommissioning funding costs and table estimating that escalation for 20 years.

13. Provide a summary written report satisfying the NRC requirements. The final report shall follow and conform to the requirements of NUREG 1757 and satisfy the breakdown of cost components as specified.

Contractor Qualifications and Requirements:

1. Contractor Personnel

a. Radiation worker training: All on-site contractor personnel requiring access to radiologically restricted areas shall be trained radiation workers. All contractor personnel shall also receive sufficient site-specific training to satisfy NIST license requirements.

b. Safety: All contractor personnel shall be trained in and comply with applicable Occupational Safety and Health Administration (OSHA), NRC, and NIST safety procedures.

2. All operations on NIST premises shall be conducted in conformance to NIST NRC licenses and policies.

3. All operations shall be planned and implemented to assure doses are maintained AS Low AS Reasonably

Achievable.

4. All individuals shall use appropriate NIST supplied dosimetry.

5. Operations shall be conducted with appropriate precautions to minimize the potential for personnel or facility contamination or release of material or contaminants to unrestricted areas. Should contamination or facility damage occur the contractor shall assure the facility is restored to the original conditions.

6. All on site operations shall be coordinated with the NIST Contracting Officer Representative (COR) and NIST Radiation Safety Division staff to assure adequate monitoring and oversight.

7. The contractor shall assure any samples to be removed from the NIST facility for analysis are handled and transported in accordance with appropriate Department of Transportation (DOT) and NRC regulatory constraints.

8. The contractor shall provide personnel trained and qualified to be operators of any required equipment such as forklifts, core boring and sampling devices, hoists or other materials handling systems.

Government supplied facilities and materials:

1. While on site the contractor personnel may have access to NIST supplied survey instruments and assistance with Radiation Safety Division analytical laboratory equipment measurements and facilities as necessary for source assessment. These shall include dose rate measurement (Inovisions 451 ion chambers) and contamination measurement survey instrumentation (TBM-3 pancake GM and NaI hand held survey instruments), a liquid scintillation counter, gas proportional counters, air sampler, Laboratory X-ray and Gamma ray spectroscopy, a hand held NaI based isotope identifier, and a laboratory fume hood. (NOTE:

Should scheduling conflicts arise, ongoing or required NIST Radiation Safety Division utilization shall take priority over contractor access or use of the equipment.)

2. NIST will furnish basic materials handling equipment such as a standard pallet jack as available.

3. Subject to escort requirements for security or radiological training, contractor personnel shall have access to NIST building 245 facilities as required to perform their tasks.

4. The contractor must provide or subcontract for any additional materials handling equipment or tools such as cranes, or heavy-duty pallet jacks, core drills, portable air handling and filtration equipment, enclosures, HEPA vacuums, or specialized tools, shielding or equipment necessary to perform the tasks.
