20555 PLANT HATCH - UNITS 1 AND 2 NRC DOCKETS 50-321, 50-366 OPERATING LICENSES DPR-57, NPF-5 RESPONSE TO NRC GENERIC LETTER 88-11 NRC POSITION ON RADIATION EMBRITTLEMENT OF REACTOR VESSEL MATERIAL ANL ITS IMPACT ON PLANT OPERATIONS Centlen n:
The subject generic letter dated July 12, 1988 requested that licensees use the methods described in Revision 2 to Regulatory Guide 1.99 to predict the effect of neutron radiation on reactor vessel materials as required by paragraph V. A of 10 CFR 50, Appendix G unless other methods could be justified. The generic letter also requested that a proposed schedule be provided for any actions that might be necessary as a result of the analysis.
General Electric, under contract to Georgia Power Company, performed the required anslysis for Plant Hatch, Units 1 and 2.
Enclosures 1 and 2 to this letter provide a comparison of Regulatory Guide 1.99 Revisions 1 and 2 for Plant Hatch Units 1 and 2 respectively. The impact of implementing Revision 2 of Regulatory Guide 1.99 can best be determined by comparing the Revisions 1 and 2 adjusted reference temperature (ART) values.
The Revision 2 ART values at 32 ef fective full power years (EFPY) for both units are below 200*F, which is the allowable limit in 10 CFR 50, Appendix G.
Therefore, implementation of Revision 2 will not result in any additional analyses, testing, or provisions for thermal annealing.
The ART values for Unit 1 which apply to the current pressure-temperature (P-T) curves are 97'F at eight (8) EFPY and 184'F at 32 EFPY.
The maximus Revision 2 ART values are 103.4*F at eight EFPY and 159'F at 32 EFPY.
Therefore, the P-T curves that would be generated using Revision 2 are slightiv more conservative than the curves currently applicable at eight EFPY. The current P-T curves and curves that could be generated using Revision 2 would be equal at approximately twelve EFPY.
After that, the current correlation for ART in more conservative than Revision 2 would be at 32 EFPY.
The conservatism is as much as 25 percent, h

U. S. Nuclear Regulatory Commission November 18, 1988 Page Two The ART values for Plant Hatch, Unit 2 which apply to the current P-T curves are 64*F at eight EFPY and 119'F at 32 EFPY. The maximum Revision 2 ART values are 76.9'F at eight EFPY and 143.1'F at 32 EFPY.
Therefore, the P-T curves that would be generated using Revision 2 are more conservative than the curves currently applicable to Unit 2.
Based on the forgoing discussion and review of the data provided in Enclosures 1 and 2, the following is proposed by GPC.
Unit 1 - The cur.*ent P-T curves, which are valid through sixteen (16)
EFPY, are conservative compared to Revision 2 predictions. While refinements to the P-T curves for pressure testing produce current curves slightly non-conservative belov twelve EFPY: the current P-T curves are approximately equivalent to those that would be generated using Revision 2 at twelve EFPY.
Af ter twelve EFPY, the current P-T curves are more conservative.
The next surveillance capsule is scheduled f or removal at fifteen FFPY. Any changes to the P-T :urves should incorporate f. hat survelliance data. Therefore, GPC believes that the current P-T curvos for Unit 1 are satisfactory for operation through sixteen EFPY. An evaluation will be made to determine the appropriate course of action upon completing sixteen EFPY.
Unit 2 - The correlation for the nil-ductility reference temperature (RTNDT) shif t for Revision 2 is more conservative than the present analysis by about 10*F for current operation.
The Revision 2 shif t correlation will continue to be more conservative than the current shift as operating time increases.
Therefore GPC plans to revise the P-T curves in accordance with the instructions of Revision 2 of Regulatory Guide 1.99 by the end of the second refueling outage following the effective date of that regulatory guide (May 31, 1988).
It is expected that the data from the first surveillance capsule will be available at that time for consideration in thn analysis.
Should you have any questions, please contact this office.
