Technical Specification 2.4(a)
March 29, 2013 U. S. Nuclear Regulatory Commission ATTN: Document Control Desk Washington, DC 20555-0001 Peach Bottom Atomic Power Station (PBAPS) Unit 1 Facility Operating License No. DPR-12 NRC Docket No. 50-171
Subject:
PBAPS Unit 1 Decommissioning Status Report - 2012 In accordance with Peach Bottom Atomic Power Station, Unit 1 Technical Specifications, an annual report is required to:
Describe the results of facility radiation surveys, Report the quantities of radioactive effluents released, Report the status of the facility and evaluate the performance of security and surveillance measures, and Provide containment vessel accumulated water analyses, as applicable.
Radiation Surveys:
Radiological surveys are performed semi-annually in the exclusion area. There were no significant concerns detected. There was one survey point (S-30) that exceeded the specified value of 1 mR/hr by 0.1 mR/hr, in accessible areas. This survey point was added due to the removal of a barrier to promote air circulation in the containment building to minimize condensation concerns within the building. When it was discovered that the dose rate was above the specified value, an engineering change was completed to reinstall the barrier. Installation of the barrier is scheduled for completion in 2013. All smearable contamination levels were less than 1000 dpm/1 00cm 2 beta-gamma.
Quantities of Radioactive Effluents Released:
There were no gaseous releases and no unplanned liquid releases from Unit 1 to the environment. As discussed below under the section entitled, "Containment Vessel Accumulated Water Analyses", there were planned discharges of liquid effluents to the river, through an approved pathway.
Status of Facility and an Evaluation of the Performance of Security and Surveillance Measures:
There were no significant events involving Unit 1. All checks were determined to be satisfactory with no significant issues identified. The unit remains in the SAFSTOR status of decommissioning. All exclusion area barriers as described in the Technical Specifications are maintained locked except when opened to provide access and egress for inspections, surveys, or repairs. Exclusion area barriers have not degraded from previous reports.
Containment Vessel Accumulated Water Analyses:
Approximately 209.4 gallons of water accumulated in Peach Bottom Unit 1 Containment Sump. Water was removed from the containment sump and transferred to Peach Bottom Units 2 & 3 for eventual release through the Laundry Drain portion of the Radwaste System, an approved release path.
The containment sump water was analyzed for tritium and gamma-emitting nuclides.
The average annual tritium concentration for the 12-month period was 3.35E-03 PCi/mL; the maximum tritium concentration was 3.49E-03 pCi/mL. All gamma-emitting nuclide concentrations were below detectable levels.
Monitoring wells for the Radioactive Groundwater Protection Program in the vicinity of Unit 1 remain at normal background levels. All tritium concentrations were below detectable level in these wells.
There are no regulatory commitments contained in this letter. If you have any questions, please contact Robert Reiner at 717-456-3608.
