OFFICE OF NUCLEAR REACTOR REGULATION REQUEST FOR ADDITIONAL INFORMATION REGARDING LICENSE AMENDMENT FOR THE PENNSYLVANIA STATE UNIVERSITY BREAZEALE NUCLEAR REACTOR LICENSE NO. R-2 DOCKET NO.50-005 The U.S. Nuclear Regulatory Commission is in the process of reviewing your application dated February 7 2012 for amendment of Facility Operating License No. R-2 for the Pennsylvania State University (Penn State) Breazeale Reactor. The amendment regards the reactor bay ventilation system upgrade which impacts the license technical specifications. During our review, questions have arisen for which we require additional information and clarification.
Following receipt of the additional information, we will continue our evaluation of your amendment request
- 1. Please specify ALL modifications you have made to your Technical Specifications (TS) that were submitted with your amendment request and provide brief justifications to each and every one of them accordingly.
- 2. Please clarify how many fans are associated with the new ventilation system. In your application, you identified that there are two roof top exhaust fans and one emergency fan. However the Safety Analysis Report Section 6.1, Summary Description, attached to your application, states there are three fans associated with the new Reactor Bay Heating, Ventilation, Air Conditioning, and Exhaust System plus one for the Emergency Exhaust System.
- 3. Under TS 3.3.3, you have requested to remove the requirement that the air particulate monitor activate the building evacuation alarm. Please provide detailed justification to support your request. Specifically, state your reasoning and the resulted safety impact for this modification; how this modification will change the current emergency procedure; under what circumstances this change will benefit your reactor operation; and how reactor personnel and public safety will not be compromised because of this change.
- 4. Under TS 3.5, you have requested to increase the reactor operation time pertaining to the emergency exhaust fan operability from 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> to 30 days. In addition, you have also proposed a new one (1) hour window to allow the reactor to operate without ANY exhaust fans. Provide detailed justification to support these change requests. Please provide your safety analysis results to support the increases to demonstrate that there will be no increased (or very minimum) safety risks to the reactor personnel and/or to the reactor due to these proposed changes.
- 5. Under TSs 3.6.3, 3.6.4, 4.6.2, and TS 4.6.3, you have requested to remove those sections regarding argon-41 (Ar-41) and as low as reasonably achievable (ALARA)
Enclosure
specifications. While realizing those requirements are codified in 10 CFR Part 20, what (where) are your commitments to those requirements after the removal of these reference TS sections?
- 6. Please provide clarifications to TS 5.5 regarding air exhaust stack height at the roof level. In your application, you are using 34 feet above reactor bay floor versus the current TS version as 24 feet above ground level. Is this only a reference change or is this an air stack height change to reflect the new ventilation system? Please justify for this change accordingly.
