SUBJECT:
CORRECTION TO PROPOSED AMENDMENT TO TECHNICAL SPECIFICATIONS REGARDING REACTOR BAY VENTILATION SYSTEM UPGRADE AT THE PENN STATE BREAZEALE REACTOR (EPID L-2019-LLA-0089)
To Whom It May Concern:
In the most recent response to a request for additional information regarding a proposed ventilation system upgrade at the PSU Breazeale Reactor (R-2), a new version of section 3.5 of the Technical Specifications was submitted to the NRC that omitted clause 3.5.b, which states: "If the reactor is operating, at least one facility exhaust fan SHALL be operating and, except for periods of time less than 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> during maintenance or repair, the emergency exhaust system SHALL be operable."
A new requirement based on maintaining negative differential pressure in T.S 3.5.a obviates the need for the requirement that at least one facility exhaust fan to be operating. However, it is necessary to maintain the requirement that "except for periods of time less than 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> during maintenance or repair, the emergency exhaust system SHALL be operable." Therefore please replace the version of TS 3.5 that was sent with the RAI response in December 2019 with the enclosed version, which reintroduces the requirement that the emergency exhaust system must be operable whenever the reactor is operating, except for short periods of time to allow for maintenance or repair.
Please contact me with any questions.
