VOGTLE ELECTRIC GENERATING PLANT j
REVISIONSTO INSERVICE TESTING PROGRAMS i
In accordance with the requirements ofTechnical Specification 4.0.5 concerning surveillance requirements, Georgia Power Company submits the enclosed revisions to the -
j Inservice Testing (IST) Programs for Vogtle Electric Generating Plant, Units 1 and 2 (VEGP-1 and 2). The IST programs were previously submitted to the NRC as documents j
ISI-P-008 and ISI-P-016 for VEGP-1 and 2, respectively. The enclosed IST program '
l changes represent Revision 8 for VEGP-1 and Revision 5 for VEGP-2. The IST-4 programs currently in effect for VEGP-1 and 2 were written to the requirements of the 1983 Edition of the American Society ofMechanical Engineers (ASME) Boiler and '
j Pressure Vessel Code,Section XI with Addenda through Summer 1983. The enclosed i
documents supersede portions of the original IST programs previously submitted to the
]
NRC. A summary of changes resulting from each of the revisions is provided in the 1
enclosures and precedes the affected IST program document pages.
i i
j A brief discussion of the revisions to the IST programs for VEGP-1 and 2 follows:
VEGP-1 Changes resulting from Revision 8 of the VEGP-1 IST program include the following:
. 11 o Revision of the pump test circuit for the Centrifugal Charging Pumps, o New pump curves for the Centrifugal Charging Pumps, o Addition of Cold Shutdown Justification CS-41, o Withdrawal of Cold Shutdown Justification CS-35, and o Revision of existing Cold Shutdown Justification CS-36.

k GeorgiaPower n U. S. Nuclear Regulatory Commission LCV-0389 Page Two Flow-limiting orifices were added to the discharge of Centrifugal Charging Pumps 1-1208-P6-002 and 1-1208-P6-003. The drawings showing the pump test circuits were revised to show the orifices.
The impellers for Centrifugal Charging Pumps 1-1208-P6-002 and 1-1208-P6-003 were replaced. As a result, new pump curves were inserted in the VEGP-1 IST Program document to reflect the characteristics of the new pump impellers.
i The testing frequency of Residual Heat Removal (RIIR) System valve 1-HV-8804B was changed from quarterly to cold shutdown. Cold Shutdown Justification CS-41 was added tojustify the change in test frequency.
Cold Shutdown Justification CS-35 was withdrawn. The affected valves,1-HV-8716A and 1 HV-8716B which are located in the RHR System, are tested quarterly rather than at cold shutdown. As a result, Cold Shutdown Justification CS-35 is no longer required.
Cold Shutdown Justification CS-36 was revised to show the RHR suction check valves 1-1205-U6-001 and 1-1205-U6-002 being partial stroke exercised quarterly and full stroke exercised at cold shutdown.
VEGP-2 Changes resulting from Revision 5 of the VEGP-2 IST Program include the following:
o Revision of the pump test circuit for the Centrifugal Charging Pumps, o Deletion of the Centrifugal Charging Pumps alternate mini-flow relief valves, l
o Revision of the valve test list, and j
o Addition of Cold Shutdown Justification CS-41.
i Test circuit drawings for Centrifugal Charging Pumps 2-1208-P6-002 and 2-1208-P6-003 were revised to show the new configuration of the alternate mini-flow lines.
The Centrifugal Charging Pumps alternate mini-flow relief valves 2-PSV-8510A and 2-PSV-8510B were deleted as a result of a plant design change. Accordingly, valves 2-PSV-8510A and 2-PSV-8510B have been deleted from the VEGP-2 IST Program.

The new manual globe valves are identified as 2-1411-U4-676,677,678, and 679. The 1
valve list was revised to reflect the new valve types and tag numbers.
l Thc testing frequency of RHR System valve 2-HV-8804B was changed from quarterly to cold shutdown. Cold Shutdown Justification CS-41 was added to justify the change in test frequency.
l The enclosed revisions to the IST Programs for VEGP-1 and 2 were reviewed against i
NRC Generic Letter 89-04. It is our belief that the enclosed revisions fall within the provisions of the subject Generic Letter and, as such, do not require prior NRC review l
and approval. We are submitting these revisions to the NRC in order to maintain the l
accuracy of the VEGP-1 and 2 IST Program documents currently on file with the NRC.
Should there be any questions in this regard, please contact this office.
