0.10-1 Amendment Nos.and 10.0 BASES FOR SURVEILLANCE RE UIREMENTS 0.0.1 This specification provides a grace period so that intervals may be adjusted to accommodate normal test schedules.

0.0.2 This specification provides guidance for surveillance requirements when the reactor is in a shutdown condition.

0.0.3 This specification ensures that inservice inspection of ASME Code Class 1, 2, and 3 components and inservice testing of ASME Code Class 1, 2, and 3 pumps and valves will be performed in accordance with a periodically updated version of Section XI of the ASME Boiler and Pressure Vessel Code and Addenda as required by 10 CFR 50.55a.Relief from any of the above requirements has been provided in writing by the Commission and is not a part of these Technical Speci f ications.This specification includes a clarification of the frequencies for performing the inservice inspection and testing activities required by Section XI of the ASME Boiler and Pressure Vessel Code and applicable Addenda.This clarification is provided to ensure consistency in surveillance intervals throughout these Technical Specifications and to remove any ambiguities relative to the frequencies for performing the required inservice inspection and testing activities.

l-Under the terms of this specification, the more restrictive requirements of the Technical Specifications take precedence over the ASME Boiler and Pressure Code and applicable Addenda.B0.0-1 Amendment Nos.and BASES FOR REACTOR COOLANT SYSTEM IN-SERVICE INSPECTION This specification ensures that inservice inspection of ASME Code Class 1, 2, and 3 components and inservice testing of ASME Code Class 1, 2, and 3 pumps and valves will be performed in accordance with a periodically updated version of Section XI of the ASME Boiler and Pressure Vessel Code and Addenda as required by 10 CFR 50.55a.This is accomplished by referencing the inspections required by Specification 0.0.3.MISCELLANEOUS INSPECTIONS Reactor Coolant Pum Fl wheels The flywheels shall be visually examined per the recommendations of Regulatory Position CA.b of Regulatory Guide 1.10 Revision 1, August 1975.Materials Irradiation Surveillance S ecimens The reactor vessel surveillance program includes eight specimen capsules to ev'aluate radiation damage based on pre-irradiation and post-irradiation testing of specimens.

The specimens are located about 3" from the vessel wall at the axial midplane.Capsule No.1 is scheduled to be removed at the first region replacement.

The exposure of this capsule leads the vessel maximum exposure by a factor of 2.1.Thus~this capsule provides information for approximately a four-year exposure to the vessel.Capsule No.2 is scheduled to be removed at the fourth region replacement.

This capsule leads the vessel maximum exposure by a factor of O.S and thus will provide data for a four-year exposure to the vessel.This sample also contains weld metal which is not present in Capsule No.l.Capsule No.3 leads the vessel maximum exposure by a factor of 2.2 and is scheduled to be removed after twenty years.Thus, sample No.3 will provide data for an exposure to the vessel of approximately forty years.Capsules No.0 and 5 lead the maximum vessel exposure by factors of 0.7 and 0.5, respectively.

Thus, Capsule No.0, which is scheduled to be removed after thirty years, provides data for a vessel exposure of twenty-one years and Capsule No.5, which is scheduled to be removed at forty years, provides data for a vessel exposure of twenty years.In addition to the capsules discussed above, there are three spares.Steam Generator Tube Ins ection The Surveillance Requirements for inspection of the steam generator tubes ensure that the structural integrity of this portion of the RCS will be maintained.

The program for inservice inspection of steam generator tubes is based on a modification of Regulatory Guide 1.83, Revision l.Inservice inspection of steam generator tubing is essential in order to maintain surveillance of the conditions of the tubes in the event that there is evidence of mechanical damage or progressive degradation due to design, manufacturing errors, or inservice conditions that lead to corrosion.

In service inspection of steam generator tubing also provides a means of characterizing the nature and cause of any tube degradation so that corrective measures can be taken.B0.2-1 Amendment Nos.and

~~t I The plant is expected to be operated in a manner such that the secondary coolant will be maintained within those parameter limits found to result in negligible corrosion of the steam generator tubes.If the secondary coolant chemistry is not maintained within these parameter limits, localized corrosion may likely result in stress corrosion racking.The extent of cracking during plant operation would be limited by the limitation of steam generator tube leakage between the primary coolant system and the secondary coolant system (primary-to-secondary leakage=I gallon per minute, total).Cracks having a primary-to-secondary leakage less than this limit during operation will have an adequate margin of safety to withstand the loads imposed during normal operation and by postulated accidents.

Operating plants have demonstrated that primary-to-secondary leakage of I gallon per minute can readily be detected by radiation monitors of steam generator blowdown.Leakage in excess of this limit will require plant shutdown and an unscheduled inspection, during which the leaking tubes will be located and plugged.Wastage-type defects are unlikely with the all volatile treatment (AVT)of secondary coolant.However, even if a defect of similar type should develop in service, it will be found during scheduled inservice steam generator tube examinations.

Plugging will be required of all tubes with imperfections exceeding the plugging limit which, by the definition of Specification 0.2.5.0.a is 0096 of the tube nominal wall thickness.

Steam generator tube inspections of operating plants have demonstrated the capability to reliably detect degradation that has penetrated 2096 of the original tube wall thickness.

4 Whenever the results of any steam generator tubing in-service inspection fall into Category C-3, these results will be promptly reported to the Commission pursuant tb Specification 6.9.2.a prior to resumption of plant operation.

Such cases will be considered by the Commission on a case-by-case basis and may result in a requirement for analysis, laboratory examinations, tests, additional eddy-current inspection, and revision of the Technical Specifications, if necessary.
