The proposed change involves TS 3/4.5.2, Emergency Core. Cooling Systems, ECCS Subsystems - T a 280 0F, which requiresthattheECCSpipingbeverifiedfullofw$Edrbyventingthe ECCS pump casings and discharge piping high points at least once per 18 months in accordance with Surveillance Requirement 4.5.2.b. The proposed change would allow a deferment of Surveillance Requirement 4.5.2.b for the ECCS flowpath containing HPI pump 1-2 until the Tenth Refueling Outage, which is scheduled to begin April 8, 1996. The current TS Action Statement 3.5.2.a requires that, due to the inoperability of ECCS subsystem Train 2, the plant be placed in Hot Shutdown (Mode 4) within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> of the expiration of the 72-hour allowed outage time on March 7, 1996, at 1354 hours0.0157 days <br />0.376 hours <br />0.00224 weeks <br />5.15197e-4 months <br />.

ECCS subsystem Train 2 is considered inoperable due to the discovery on l March 4, 1996 that Surveillance Requirement 4.5.2.b cannot be met for a section of High Pressure Injection Pump 1-2 discharge piping downstream of normally closed motor operated discharge valve HP2A.

Toledo Edison requests that the enclosed license amendment application be approved and issued as an emergency license amendment in the manner l allowed by 10 CFR 50.91(a).
