. 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 in serious accident or transient. This procedure will be implemented while.the system is at operating pressure with the pump (s) running.

4.2 Signoff steps marked "SO" in the left-hand margin of the body of the procedure require a signoff on the Data l Sheet or Prccedure Cover Sheet.

! 4.3 Leak Rates of greater than 5 drops per min. (.25 cc/ min) shall be quantified. Put "< .25 cc/ min" on the Data Sheet, Att-achment A, in the space provide'd for components with leak rates less than or qual to 5 drcps per min.

4.4 Data Sheet steps marked (*) are specific Tech. Spec. I requirements which will fail the test if not completed j satsifactorily.

l 4.5 If any component is found to be exhibiting excessive l leakage notify SSVN immediately. '

5.0 PREREQUISITES 5.1 Request RWP & HP assistance when required.

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 Core Spray Loop must be running for Surveillance Test ST-6-052-231-1 or per operating procedure S52.9.A for the inspection.

5.5 Coordinate with operator running the system to allow pump run durations to be extended for the inspection.

6.0 PROCEDURE IT IS THE RESPONSIBILITY OF THE PERSON OR PERSONS PERFORMING THIS TEST TO ENSURE ALL BLANKS AND DATA SHEETS ARE CORRECTLY AND COMPLETELY FILLED IN.

6.1 Preparation SO 6.1.1 Verify all prerequisites are satisfied.

6.1.2 Record appropriate information for each piece of measurement and test equipment used with a PECo number on the Data Sheet.

6.2 Shift Permission to Test SO 6.2.1 Obtain Shift Supervision's (SSVN's) permission to start test.

l SO 6.2.2 Obtain Control Room Operator's permission to j start test.

THE ACTUAL LEAKAGE RATE MEASUREMENT METHODS 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 20 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 i

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 i

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

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