DRAFT REQUEST FOR ADDITIONAL INFORMATION Concerning the Vermont Yankee Amendment Request PCN-254 Current TS 3.10.B.3.a and TS 3.5 appear to convey that when the delayed offsite ac source and one train of safe guards equipment (e.g., Low Pressure Core Cooling Systems) are inoperable, plant operation is permitted for 7 days. Similarly, current TS 3.10.B.3.b, TS 3.5, and TS 3.10.B.1 appear to convey that when the delayed offsite ac source, one diesel generator ac source, and the train of safe guards equipment supported by this one diesel generator ac source are inoperable, plant operation is permitted for 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. These current technical specifications appear to be consistent with the intent of the STS. However, by letter dated February 26, 2002, it appears that the above 7 day and 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> allowed times of plant operation before shutdown are proposed to be changed to zero time or immediate shutdown. Provide clarification.
