1.0l PURPOSE i This procedure provides instructions for performing leak tests on the RHR Loop 30 Suction Stop Valves, MOV-3-750 and MOV-3-751. These test shall be performed during Unit 3 heatup as directed by OP-0202.1, Reactor Startup - Cold Conditions to Hot Standby Conditions. This surveillance satisfies the requirements of reference 2.1.2 and 2.1.3, for the valves tested.

2.0 - REFERENCES / RECORDS REQUIRED 2.1 References l

3.2 Personnel who will perform this procedure have reviewed it and understand their responsibilities.

3.3 Technical Department personnel have calculated the maximum allowable leak rate from previous test data, and recorded it on Attachments 1 and 2.

3.4 The Plant Supervisor - Nuclear has authorized performance of this test.

4.0 PRECAUTIONS / LIMITATIONS 4.1 -All work performed in Radiation Controlled Areas shall be performed in accordance with the requirements of the Radiation Work Permit and the ALARA program.

4.2 The Plant Supervisor - Nuclear' shall be notified immediately. if any acceptance criteria is not met or any malfunction or abnormal conditions occur.

4.3 - If either MOV is declared inoperable due to this test Technical Specification Section 3.16 should be referred to for required actions.

4.4 All RCS and RHR ressure gauges used during the performance of this .

procedure shall have een calibrated within 18 months of the test date.

4.5 During the performance of this procedure it may be required to drain aressurized pipe lines containing high temperature radioactive water.

Insure that the lines are drained by use of a properly secured drain going to the containment sump or the waste hold up tank.

4.6 The differential pressure across each valve being tested shall be at least 150 psig throughout the test.

4.7 The observed leak rate shall be corrected to normal system pressure to obtain actualleak rate.
