Appendix C
SELECTED MAINTENANCE ACTIVITIES AND POSTMAINTENANCE TESTS
Maintenance Activity
Recommended Test
Perform maintenance of
emergency diesel generator
(EDG) and related components.
1.
Test automatic-start function.
2.
Check EDG fluid parameters (e.g., lube- oil
level, cooling-water temperature and flow,
governor-control oil system, fuel-oil sampling).
3.
Test EDG automatic protective features
(overspeed, generator differential, low
lube-oil pressure, high crankcase pressure,
etc.).
4.
Test EDG synchronization and load.
5.
Test EDG manual start.
6.
Check diagnostic baseline parameters (e.g.,
vibration, cylinder compression).
7.
Check voltage regulation and frequency.
Perform heat-exchanger maintenance.
1.
Check heat-exchanger parameters
(temperature, flow, external leakage, etc.).
2.
Test heat-exchanger performance (heat
balance).
3.
Check hydrostatic or operational test for tube
and tube-sheet leakage.
Perform piping-system maintenance.
1.
Flush system.
2.
Check ASME code requirements.
3.
Perform pressure/hydrostatic test.
4.
Check integrity of mechanical joints.
5.
Check cleanliness and verify system filled and
vented.
6.
Verify correct fluid-chemical parameters.
7.
Verify that piping supports heat tracing, and
insulation are restored.
8.
Review for unusual pipe displacement.
9.
Ensure that instrumentation lines are attached
to pipe and properly refilled.
