.KSK/RSE:mjl 1.0 PURPOSE To inspect and measure any leakage of RER system components that are directly associated with system piping that could carry contaminated fluids during a serious accident or transient.
This inspection shall be implemented while the RHR loop is operating in the. Shutdown Cooling Mode or in the test mode.

..KSK/RSE:mjl 4.3 Leakage rates of greater than 5 drops per min (.25 1
cc/ min) shall be quantified.
Put ".25 cc/ min" on Data Sheet Attachment A for components with leakage rates of 5 drops per min or less.
4.4 Data Sheet steps marked (*) are specific Tech. Spec.
requirements which will fail the test if not completed satisfactorily.
4.5 If any component exhibits excessive leakage notify SSVN immediately.
5.0 PREREQUISITES 5.1 RLgaest RWP and HP assistance when needed.
5.2 Inspector is familiar with the RHR system layout and location.
5.3 Obtain a copy of the previous inspection's Data Sheet Attachment A.
5.4 RHR piping is at operating pressure during this inspection for ST-6-051-232-1 or per Operating Procedures S51.8.A and S51.8.B.
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 and verify the equipment is within j
it's calibration period.

..KSK/RSE:mjl 6.2 Shift Permission tc *est SO 6.2.1 Obtain Shif Supervision's (SSVN's) permission to start test.
SO 6.2.2 Obtain Assistant Control Room Operator's permission to start test.
6.3 RER System Contaminated" Piping Inspection ACTUAL LEAKAGE RATE MEASUREMENT METHODS WILL BE LEFT TO THE DISCRETION OF THE INSPECTOR.
THE ONLY GUIDELINES
~ ~ ~
BEING THAT ALL DATA WILL BE A MEASURED QUANTITY 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 MIN.
(CC/ MIN.)
SO 6.3.1 Mark in the Data Sheet the mode of operation for the "B" Loop during this inspection.
6.3.2 For all in line components that exhibit leakage, within boundaries of Attachment B, record on the Data Sheet the leakage rate and a description of the location of the leak.
Pay
[LdkT particular attention to system components identified as having exhibited measurable leakage in the previous inspection.
- C t; CI"5 " " I" d'" ='"
include the components within So the dashed boundaires of Attachment B.
6.3.4 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 Results Evaluation SO 6.4.1 Compare the leakage rate 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.
6.4.2 If any component's leakage rate has increased significantly since the last inspection prepare I
a MRF to repair the component.
I 6.4.3 If any component's leakage is a major portion c%dW of the overall system leakage limit prepare a g
MRF for its repair.
