- 1. INTRODUCTION This report is submitted to the United States Nuclear Regulatory Commission (NRC) pursuant to section 15.1 of Appendix A, of the Technical Specifications (License R-77) for the Buffalo Materials Research Center (BMRC) located at the State University of New York at Buffalo. It summarizes changes to the facility, major maintenance activities, surveillance tests and inspections, radiation surveys, and radioactive effluents for the 2005 calendar year. The facility remained in Possession Only License status throughout the year. All required surveillance was completed.
- 2. MAJOR MAINTENANCE Several routine maintenance activities were undertaken in the B.M.R.C. However, there were no maintenance activities undertaken in 2005 that would qualify as major maintenance.
The major activity undertaken in calendar year 2005 was the transfer, packaging, and shipment of the reactor spent fuel to a Department of Energy facility pursuant to N.R.C. regulations. The fuel was successfully shipped in conjunction with United States Department of Energy personnel and a contractor.
- 3. 10CFR 50.59 CHANGES There were no 50.59 reviews performed during the 2005 calendar year.
- 4. RADIOACTIVE EFFLUENTS 4.1 Controlled Discharges to the Sanitary Sewer There were two controlled discharges to the sanitary sewer system in 2005. The total volume of water released was 60,200 liters, containing a total of approximately 0.0 13 millicuries of radioactivity. Both releases were from the 10,000 gallon above ground waste storage tank (referred to as 10K Tank).
Tables 1 and 2 contain the discharge information specific to the releases including comparisons to the monthly average concentration in 10 CFR Part 20, Appendix B, Table 3 "Releases to Sewers" and the sum of the fractions.
4.2 Airborne Releases No airborne radioactive releases, other than natural background resulting from radon and its daughter products, were made during 2005. A sensitivity determination (AiCi/cc/cpm) of the building air system (based on the injection of a known quantity of Kr-85 gas) was performed prior to moving reactor fuel.
There were no releases resulting from the spent fuel removal activities.

- 5. ENVIRONMENTAL RADIOLOGICAL SURVEYS 5.1 Routine Surveys The direct radiation levels outside the BMRC reactor building are routinely monitored adjacent to the "truck door" access area and on the roof of the liquid waste holding tank vault.
Global Dosimetry Solutions dosimeters are used to monitor integrated radiation levels in six exterior areas around the facility and six locations within the building itself. These dosimeters are replaced with a new badge every month and the previous month's badge is sent to the dosimetry vendor for processing. The vendor is NVLAP certified. The minimum photon sensitivity for the dosimeters is 5 mrem.
Tables 3 lists the cumulative annual summary of the environmental radiation dose equivalent from the environmental badges located around the facility. The maximum cumulative annual deep dose equivalent reading was 34 mrem on the dosimeter (# 2116) located on the roof of the vault containing the above ground waste holding tank.
Table 4 lists cumulative annual summary of the radiation dose equivalent from the area dosimetry badges located within the building. The maximum cumulative annual deep dose equivalent reading was 90 mrem on the dosimeter (# 2815) located on the bridge located directly above the reactor pool.
Semi-annual "tell-tale" samples are drawn and analyzed from the sampling well tubes adjacent to the underground liquid waste holding tanks (Tank #1). These analyses detected no radioactivity in excess of background levels.
- 6. RADIATION EXPOSURES 6.1 External Dosimetry Dosimetry records were maintained for a total of seven staff members and other authorized facility entrants. Film dosimeters provide X, beta, and gamma exposure monitoring. Thermoluminescent dosimeter (TLD) rings are used to measure extremity dose for selected personnel. Also, a TLD for neutron detection is available when necessary. All dosimeters are processed by Global Dosimetry Solutions, a NVLAP certified vendor. These dosimeters are replaced on a bimonthly basis.

University at Buffalo The State University of New York Environment, Health & Safety Services The film dosimeters have a minimum sensitivity of 10 mrem for both beta and photon radiation. A separate neutron sensitive dosimeter (with a minimum sensitivity of 20 mrem per monitoring period) is available and is worn by personnel during manipulations involving the reactor fuel or plutonium -
beryllium (PuBe) sources.
During 2005 no monitored individual received a measurable whole body deep dose equivalent.
University Police Department officers perform routine security tours of the building. The patrol officers wear a University Police dosimeter pack when they perform these walkthroughs. These dosimeters did not record any dose equivalent during 2005.
Four visitor dosimeter packs are also available. These dosimeters are issued to visitors who may need to enter into areas requiring exposure monitoring. None of these visitor dosimeters recorded any measurable dose equivalent in 2005.
Tables 5 and 6 provide summaries of personnel whole body and extremity dose for the spent fuel shipping activities performed in calendar year 2005. There was no whole body dose received by any of the BMRC, University at Buffalo, Department of Energy, or Contractor staff working on the project.
Extremity dose was received by four BMRC staff members and two contractor personnel. The maximum extremity dose was 100 niRem received by one of the contractor staff.
- 7. RADIATION AND CONTAMINATION SURVEYS 7.1 Exit Monitoring Exit monitoring is required as part of each egress from the reactor containment building and other radioactive materials areas within the BMRC. These surveys occasionally detect radioactive contamination, allowing rapid correction of contamination problems.
7.2 Routine Surveys The BMRC staff performs monthly radiation and contamination surveys of the BMRC building.
In calendar year 2005, contamination was detected in three controlled areas during one of these monthly surveys. These areas were subsequently cleaned and re-surveyed.

- 8. MISCELLANEOUS
- The Reactor Decommissioning Safety Committee convened three times during calendar year 2005.
This meets the annual requirement in Facility Technical Specifications for a minimum of two committee meetings.
- The fuel shipment activities and paperwork were inspected by the N.R.C. inspector during the time of the packaging and transport. All paperwork and activities were determined to be in compliance.
- Several requests for information pertaining to facility security were received from the N.R.C.
during 2005. All information requested was supplied.
