RCS Leakage Oe ection Instrumentation B 3.4.15 BASES APPLICABLE The resolution of USI-2 for Westinghouse PWRs was use of SAFETY ANALYSES fracture mechanics technology for RCS piping > 10 inches (continued) diameter (Ref. 5). This technology became known as leak-before-break (LBB). Included within the LBB methodology was the requirement to have leakage detection systems capable of detecting a 1.0 gpm leak within four hours. This leakage rate is designed to ensure that adequate margins exist to X'nyct/

T he safety significance of RCS

detect leaks in a timely manner during normal operating conditions. The use of LBB for Ginna Station is documented LEAKAGE

~pc ~

varies widely Seq epending on its source, rate, and duration. Therefore, detecting and monitoring RCS LEAKAGE into the containment area is necessary. guickly separating the identified LEAKAGE from the unidentified LEAKAGE is necessary to provide quantitative information to the operators, allowing them to take corrective action should a leak occur that is detrimental to the safety of the plant and the public.

Required corrective actions are provided in LCO 3.4. 13, RCS Operational LEAKAGE. The capability of the leakage detection systems was evaluated by the NRC in Reference 7.

R+ t egg g RCS leakage detection instrumentation satisfies Criterion 1 of the NRC Policy Statement.

LCO One method of protecting against large RCS LEAKAGE derives from the ability of instruments to rapidly detect extremely small leaks. This LCO requires instruments of diverse monitoring principles to be OPERABLE to provide a high degree of confidence that extremely small leaks are detected in time to allow actions to place the plant in a safe condition, when RCS LEAKAGE indicates possible RCPB degradation.

R.E. Ginna Nuclear Power Plant B 3.4-102 Revision 0

RCS Leakage Detection Instrumentation B 3.4.15 BASES LCO The LCO is satisfied when monitors of diverse measurement (continued) means are available. Thus, the containment sump A monitor (level or pump actuation from either sum A um in l combination with a gaseous (R-12) or articulate (R-11) radioactivity monitor provides an acceptable minimum.

Alternatively, the plant vent gaseous (R-14) or particulate (R-13) monitors may be used in place of R-12 and R-11, respectively, provided that a flowpath through normally closed valve 1590 is available and R-14A is OPERABLE.

APPLICABILITY Because of elevated RCS temperature and pressure in NODES 1, 2, 3, and 4, RCS leakage detection instrumentation is required to be OPERABLE.

In NODE 5 or 6, the temperature is c 200mF and pressure is maintained low or at atmospheric pressure. Since the temperatures and pressures are far lower than those for NODES 1, 2, 3, and 4, the likelihood of leakage and crack propagation are much smaller. Therefore, the requirements of this LCO are not applicable in NODES 5 and 6.

ACTIONS A.l.l A.1.2 and A.2 With the required containment sump A monitor inoperable, no other form of sampling can provide the equivalent information; however, the containment atmosphere radioactivity monito~s ill provide indications of changes In addition to Qa a)PERABLE gaseous ~par icu ate 'eakage.

RCS Leakage Detection Instrumentation B 3.4.15 BASES ACTIONS A. l. 1 A. 1.2 and A.2 (continued)

The containment air cooler condensate collection system is OPERABLE if the flow paths from all four containment air coolers to their respective collection tanks are available and a CHANNEL CALIBRATION of the monitor has been performed within the last 24 months. The containment air cooler condensate collection system is provided as an option for detecting RCS leakage since SR 3.4. 13. 1 is not performed until after 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months of steady state operation. Therefore, this collection system can be used, during MODE changes if the containment sump monitor is inoperable to meet the LCO.

Restoration of the required sump monitor to OPERABLE status within a Completion Time of 30 days is required to regain the function after the monitor's failure. This time is acceptable, considering the Frequency and adequacy of the RCS water inventory balance required by Required Action A. 1'.

Required Actions A. 1. 1, A. 1.2, and A.2 are modified by a Note that indicates that the provisions of LCO 3.0.4 are not applicable. As a result, a MODE change is allowed when the containment sump monitor is inoperable. This allowance is provided because other instrumentation is available to monitor RCS leakage.

Insert 1 The LBB methodology was further expanded to include the portions of the residual heat removal (RHR) system piping from its connection to the RCS hot and cold leg piping to the first motor operated isolation valve. The specific application of LBB to this piping was reviewed by the NRC and the staff concluded that, because the appropriate margins on leakage and crack size have been met given the Ginna leakage detection system capability of 0.25 gpm, it has been demonstrated that these sections of piping will exhibit LBB behavior.

Insert 2 B.1 With the gaseous (R-12) containment atmosphere radioactivity monitoring instrumentation channel inoperable (and its alternate R-14), a verification that the particulate (R-11) containment atmosphere radioactivity monitor is OPERABLE is required. The 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months Completion Time is based on the low probability of a RCS leak occurring during this time frame.

Required Action B.1 is modified by a Note that indicates that the provisions of LCO 3.0.4 are not applicable. As a result, a MODE change is allowed when the gaseous containment atmosphere radioactivity monitor is inoperable. This allowance is provided because other instrumentation is available to monitor for RCS LEAKAGE.
