, Paga 2 of 9 KSK/RSE:cjf 1.0 PURPOSE To inspect and measure any leakage from Core Spray System components that are directly associated with system piping that could carry contaminated water during a serious accident or transient. This procedure will be implemented while the system is at operating pressure with the pump (s) running.

5.2 Inspector is familiar with the system layout and location.

5.3 Copy of the last test's Data Sheet is available for comparison.

5.4 Care Spray Loop must' be running for Surveillance Test ST-6-052-232-1 or per operating procedure SS2.9.A for the inspection.

THE ACTUAL LEAKAGE RATE MEASUREMENT METBODS WILL BE LEFT TO THE DISCRETION OF THE INSPECTOR (s). THE ONLY GUIDELINES BEING THAT ALL DATA WILL BE A MEASURED QUANITY OF FLUID OVER TIME USING A STOPWATCH. DROPS PER MINUTE CAN BE USED AS A MEASUREMENT WHERE 2o DROPS

= 1CC. ALL RECORDED DATA SHALL BE IN CUBIC CENTIMETERS PER MINUTE. -

6.3.1 For all In Line components, within the boundries of Attachment B, that exhibit leakage, record on the Data Sheet their leakage rate and a description of the location of the leak. Pay particular attention to system components identified as having exhibited measurable leakage during the previous inspection.

6.3.2 From the leakage rate data on Attachment A, calculate the total system leakage rate and document the results on the Data Sheet section 6.3 6.4 Test Result Evaluation SO 6.4.1 Compare the leakage limit in 8.1 to the total system leakage rate. If the limit is exceeded N$

prepare a MRF to reduce the system leakage rate so that it is within the limit.

6.4.2 If any component's leakage rate has increased significantly since the last inspection prepare a MRF to repair the component.

6.4.3 If any component's leakage is a major portion of the overall system leakage limit prepare a MRF for its repair. i i
