Basis The operability of two PORV' s or the RCS vented through an opened PORV ensures that the Reactor Vessel will be protected from pressure transients which could exceed the limits of Appendix G to 10 CFR Part 50 when the Reactor Coolant average temperature is~ 350°F and the Reactor Vessel Head is bolted. When the Reactor Coolant average temperature is > 350°F, overpressure protection is provided by a bubble in the pressurizer and/or pressurizer safety valves. A single PORV has adequate relieving

e e TS 4;19-8 F. Reports

a. Following each inservice inspection of steam generator tubes, the number of tubes plugged in each steam generator shall be reported to the Commission within 15 days.
b. The complete results of the steam generator tube inservice inspection shall be reported on an annual basis for the period in which the inspection was completed. This report shall include:
1. Number and extent of tubes inspected.
2. Location and percent of wall-thickness penetration for each indication of an imperfection.
3. Identification of tubes plugged.
c. Results of steam generator tube inspections which fall into Category C-3 and require prompt notification of the Commission shall be reported by special report prior to resumption of plant operation. The report shall provide a description of investigations conducted to determine cause of the tube degradation and corrective measures taken to prevent recurrence.

e TS 4.19-10 withstand the loads imposed during normal operation and by postulated accidents. Operating plants have demons.trated that primary-to-secondary leakage of 500 gallons per day per steam generator can readily be de-tected 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 inservice, it will be found during scheduled inservice steam generator tube examination. Plugging will be required of all tubes with imperfections exceeding the plugging limit which, by the definition of Specification 4.19.E.a, if 40% of the tube nominal wall thickness.

Steam generator tube inspections of operating plants have demonstrated the capability of reliably detecting degradation that has penetrated 20%

of the original tube wall thickness.

Whenever the results of any steam generator tubing inservice inspection fall into Category C-3, these r.esults will be reported to the Commission by special report 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 Speci-fication, if necessary.

2. This tabulation supplements the requirements of §20.407 of 10 CFR Part 20.
  • ATTACHMENT 2 DISCUSSION OF PROPOSED TECHNICAL SPECIFICATION CHANGE Generic Letter No. 83-43 requested all licensees to revise their Technical Specifications to comply with 10CFRSO. 72 and 50. 73, 10CFRSO. 72 has been revised to indicate the immediate notification requirements for operating nuclear power reactors. 10CFRS0.73 is new and provides for a revised Licensee Event Report (LER) System.

The following changes to the Surry 1 and 2 Technical Specification should be made to comply with the new rules:

1. Throughout the Technical Specifications, revise the term "Reportable Occurence" to become "Reportable Event",
2. The definition of "Reportable Event" shall read, "a Reportable Event shall be any of those conditions specified in Section 50.73 to 10CFR Part SO.",

3, Delete Technical Specifications 6.6.2, 6.6.2.a and 6.6.2.b,

4. Throughout the Technical Specifications, delete the references to Technical Specifications 6.6.2, 6.6.2.a and 6.6.2.b,
5. Insert where applicable, the reference to Section 50.73 to 10CFR Part SO,
6. Renumber Technical Specification 6.6.a to follow the outline format of the other Surry Technical Specifications,
7. Throughout the Technical Specification revise the references to Technical Specification 6.6, In addition, minor editorial and typographical errors are corrected. These proposed changes to the Surry 1 and 2 Technical Specifications do not pose a significant hazards consideration and are administrative in nature. These changes have been requested by the Nuclear Regulatory Commission to reflect the new requirements of 10CFRS0.72 and 50.73.
