l Minimum Ltw Prscaura Cooling (nd Dimi Grn:ratar Availability 3/4.5.F i B 3/4.5 CORE AND CONTAINMENT COOLING SYSTEMS 3/4.5.F. Minimum Low Pressure Cooling and Diesel Generator Availability
' BASES l
BACKGROUND The purpose of Specification 3/4.5.F is to assure that adequate core I cooling equipment is available at all times. If, for example, one core j spray were out of service and the diesel which powered the opposite I core spray were out of service, only 2 LCPI pumps would be available. {
lt is during refueling outages that major maintenance is performed and l during such time that all low pressure core cooling systems may be out of service. This specification provides that should this occur, no work will be performed on the primary system which could lead to draining the vessel. This work would include work on certain control rod drive components and recirculation system.
Specification 3.4.F.5 allows removal of one CRD mechanism while the torus is in a drained condition without compromising core cooling capability. The available core cooling capability for a potential draining of the reactor vessel while this work is performed is based on an estimated drain rate of 300 gpm if the control rod blade sealis unseated. Flooding the refuel cavity and dryer / separator pool to elevation 114'-0" corresponds to approximately 305,000 gallons of watcr and will provide core cooling capability in the event leakage from the control rod drive does occur. A potential draining of the reactor vessel (via control rod blade leakage) would allow this water to enter into the torus and after approximately 243,000 gallons have accumulated (needed to meet minimum NPSH requirements for the LPCI and/or core spray pumps), the torus would be able to serve as a common suction header. This would allow a closed loop operation of the LPCI system and the core spray system (once re-aligned) to the torus. In addition, the other core spray system is lined up to the condensate storage tanks which can supplement the refuel cavity and dryer / separator pool water to provide core flooding, if required.
ACTION The maximum allowed out-of-service (OOS) time for one EDG is 14 days, provided that one EDG and the SBO-DG are operable, in addition to all of the low pressure core and containment cooling systems as specified in 3.5.F.1. If the SBO-DG is determined to be inoperable, the maximum allowed OOS time for one EDG is 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. A 24-hour LCO will control the plant for cold shutdown if the SBO-DG becomes inoperable anytime after 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> during a 14-day EDG LCO.
SURVEILLANCE The SBO-DG shall be determined to be operable as defined below for extending the 3 days OOS time to 14 days for an EDG. The SBO-DG is operable if a surveillance was completed within the lasi seven days before extending to a 14-day OOS; otherwise, a surveillance must be I completed to demonstrate that the SBO-DG is operable. The 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> period allows the operators to complete the required SBO-DG surveillance using the 23Kv offsite power source and to notify Commonwealth Electnc of the needed use of the 23Kv line in the testing configuration.

- BASES BACKGROUND If the discharge piping of the core spray, LPCI system, HPCI, and RCIC are not filled, a water hammer can develop in this piping when the pump and/or pumps are started. An analysis has been done which shows that if a water hammer were to occur at the time at which the system were required, the system would still perform its design function. However, to minimize damage to the discharge piping and to ensure added margin in the operation of these systems, this Technical Specification requires the discharge lines to be filled whenever the system is in an operable condition. ,
l SURVEILLANCE An acceptable method of ensuring that the lines are fullis to vent at the high points. The monthly frequency is based on the gradual nature of void buildup in the ECCS piping, the procedural controls, and operating experience.
