- 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 2011 calendar year. All required surveillance was completed.
In 2011, the University continued working with the Decommissioning Project Design Consultant, ENERCON on pre-decommissioning activities. Pre-decommissioning related activities undertaken in 2011 included:
" Completion of the Facility Site Characterization.
0 Packaging and shipment of facility legacy waste material.
" Completion of Reactor Activation Analysis and Segmentation Plan report in support of development of Decommissioning Plan.
- 2. MAJOR MAINTENANCE There were no maintenance activities performed in the BMRC during 2011 that would qualify as Major Maintenance. Only routine maintenance activities were undertaken within the BMRC.
- 3. 10CFR 50.59 CHANGES There were no 50.59 reviews performed during the 2011 calendar year.
- 4. RADIOACTIVE EFFLUENTS
- 4.
Controlled Discharges to the Sanitary Sewer There were three controlled discharges to the sanitary sewer system in 2012. The total volume of water released was 85,800 liters, containing a total of approximately 0.0164 millicuries of radioactivity. All three releases were from the 10,000 gallon above ground waste storage tank (referred to as 10K Tank). Tables 1, 2, and 3 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, occurred during 2011.
- 5. ENVIRONMENTAL RADIOLOGICAL SURVEYS Buffalo Materials Research Center 2011 Annual Report Page 3
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 were used to monitor integrated radiation levels in six exterior areas around the facility and four 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.
Table 4 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 85 mRem on the dosimeter (# 2118) located by the truck door exit from the containment building. This dose was delivered entirely from two months (August and September) during which waste containers were staged awaiting shipment.
Table 5 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 34 mRem on the dosimeter (# 1624) located on the bridge located directly above the reactor pool.
- 6. RADIATION EXPOSURES 6.1 External Dosimetry External dosimetry records were maintained for a total of five BMRC staff members, sixteen employees of the Decommissioning Project Design Consultant, and other authorized facility entrants.
Film dosimeters provide x-ray, 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 bi-monthly basis. The film dosimeters have a minimum sensitivity of 10 mrem for both beta and photon radiation.
During 2011, six individuals received measureable whole body dose. The highest whole body dose received was 31 mRem which was received by two individuals working for the Decommissioning Project consultant performing legacy waste packaging activities.
Ten individuals received measureable extremity doses in 2011. The highest extremity dose received was 336 mRem which was received by an employee of the Project consultant performing legacy waste packaging activities.
University Police Department officers perform routine security tours around the building. The patrol officers wear a University Police dosimeter pack when they enter the building. These dosimeters did not record any dose equivalent during 2011.
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 2011.

Tables 6 and 7 provide summaries of personnel whole body and extremity dose for 2011.
- 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.
Surveys are also performed after work involving the manipulation of potentially contaminated materials.
In calendar year 2011, contamination was occasionally detected during these surveys. In all such instances the contaminated areas were cleaned and re-surveyed until acceptable levels were achieved.
- 8. MISCELLANEOUS
- The Reactor Decommissioning Safety Committee convened four times during calendar year 2011.
This meets the annual requirement in Facility Technical Specifications for a minimum of two committee meetings.
