OPERATION OF THIS EQUIPMENTIS A TECHNICAL SPECIFICATION REQUIREMENT.

3.2 Liquids leaking from various components of the HHSI or RHR systems will be mildly radioactive, and appropriate health physics practices should be observed.

i 3.3 Hydro Pumps:

)

3.3.1 Hydro pump skids must be prevented from rolling (i.e., wheels chocked, brakes locked, chained to wall, etc.) to minimize the rish of RHR piping damage in a seismic event.

3.3.2 When a hydro pump is connected to a radioactive liquid system, maintain the test point valve shut until hydro pump pressure is established, and shut the test print valve before securing the hydro pump on depressurizing to prevent contamination of the hydro hose (s) and pump.

3.4 2PI-974, SI pump suction pressure gauge shall be isolated during this test, as it is outside the test boundary.

I 3.5 LHSI pump suction pressure will be read on the installed gauges in the No. 3 lower pipeway on El. 8'.

UNIT 2 INITIALS 7.0 ACCEPTANCE CRITERIA l

Leakage criteria of the Leakage Reduction and Preventive Maintenance Program are used to evaluate the leakage from safety injection system components to atmosphere. Total leakage from all post-accident system (not just safety injection system) components, located in a specific area of the plant, is limited by Criterion 1 or Criterion 2. Total post-accident system leakage from all areas of the plant is limited by Criterion 3. Thus, acceptance of these test results require their evaluation together with the results of the other post-accident system leakage tests.

8.0 ANALYSIS l

TO BE COMPLETED BY THE OPERATIONS MANAGER OR HIS REPRESENTATIVE.

8.1 Comparison with allowable ranges of test values and analysis of deviations complete.

1 8.2 Any requirements for corrective action?

Yes No If yes, give details in the rer eks sectic a and MWR No.

This test is required when the seat leakage of 2SI-854B exceeds the pumping rate of the hydro pump and test system pressure per 2PI-629 is l

<100psig per Step 5.16.

INITIALS 1.0 Shut 2RH-V2, then secure the hydro pump.

by throttling with 2SF-811.

4.0 Verify 2RH-701 shut, then open 2SF-819 and verify FI-636 flow remains at 20 gpm.

l 5.0 Shut 2RH-709B and 733B.

6.0 Open 2RH-704B to ~25% open and allow flow at FI-636 to stabilize.

7.0 Record the following data:
