PUP-S POST MAINTENANCE TESTING CRITERIA 1.0 PURPOSE The purpose of this procedure is to provide the criteria which establishes the extent of testing required following a maintenance activity.
2.0 DEFINITION Post Maintenance Testing (PMT) as used in this procedure means component or system operability testing to assure that the maintenance
- activity, be it preventative, predictive, or corrective maintenance, did not adversely affect performance of the component or
- system, regardless of who performed the work.
3.0 REFERENCES
3.1 3.2 3.4 Generic Letter 83-28 Information Notice 85-71 ASME B6PV Code, section 11 AP-5, "Procedure for Repair" 4.0 PROCEDURE 4.1 The attachment to this procedure lists, by component, the maintenance activities that might be performed and the testing required following that activity.
The supervisor who approved the WR is normally the PMT specifier.
4.2 It is the responsibility of the PMT specifier to define the testing requirements for cases not contained in the attachment, and to notify the Supervisor, Technical Support for required revision to this document.
4.3 The PMT specifier shall assure that the PMT include a test specific to the corrective maintenance performed, as well as tests to assure the proper functioning of the component and/or system.

4.4 When maintenance is performed on a
component that is part of an auxilliary system of a large component, the larger component does not necessarily need to be tested.
For
- example, maintenance on the prelubrication pump of a diesel generator does not require a
load test for any diesel maintenance.
What is required i'n this case is a pressure/flow test of the prelubrication pump.
4.5 When more than one PMT is specified, the test must be done in a
logical order, such that adjustments made during the test (tightening of valve
- packing, for example) do not invalidate a
previously performed test (stroke timing).

DEFINITIONS:
ANY:
any maintenance activity that could effect the proper functioning of the component.
Includes:
any dissassembly of the component or power supply.
Does not include removal of inspection covers on non pressure retaining components.
Does not include non intrusive maintenance, such as a visual inspection or surface cleaning.
CIIRT:
Appendix J to 10CFR50 Containment Integrated Leak Rate test INSERVICE TEST:
observation of correct operaion of the component after being placed in service.
This should be accomplished by comparison with redundant equipment or with previously known performance characteristics.
This may need to be accomplished with one or more of the following Technical Specifications tests:
Surveillance tests (ST)
Channel Calibration Sensor Check/Channel Check Instrument Channel test/Channel Functional test Source Check Non destructive examination as required by ASME B&PV code section XI.
LOCAL LEAKAGE TEST:
a test for leakage at the point of maintenance, such as a Downy Wand test.
LLRT:
Appendix J to 10CFR50 Local Leak Rate Test.
LOAD TEST:
a test
.designed to assure that the component is capable of carrying its required load.
PRESSURE/FLOW TEST:
a test designed to assure that a
fan or pump is operating on its head/capacity
- curve, or a
test designed to show that a
pressure boundary is sufficiently leak tight.
STROKE TEST:
movement of a valve or damper through a sufficient portion of its travel to assure freedom of movement.
STROKE TIMING TEST:
timing of the movement of a valve or damper through a
sufficient portion of its travel'o assure that the travel time is correct.
This test usually requires full travel unless partial travel times are previously documented.
