3.1.8 Single Loop Restrictions-Specification The following special limitations are placed on sfngle loop operation in addition to the limitations set forth in Specification 2.3.

3.1.8.1 Single loop operation is authorized for test purposes only.

3.1.8.2 At least 23 incore detectors meeting the requirements of Technical Specification 3.5.4.1 and 3.5.4.2 shall be available throughout this test to check gross core power distribution.

3.1.8.3 The pump monitor trip setpoint shall be set at no greater than 50 percent of rated power.

3.1.8.4 The outlet reactor coolant temperature trip setpoint shall be set at no greater than 610F.

3.1.8.5 At 15 percent of rated power and every 10 percent of rated power above 15 percent, measurements shall be taken of each operable incore neutron detector and each operable incore thermocouple, reactor coolant loop flow rates and vessel inlet and outlet temperature, and evaluation of this data determined to be at ceptable before proceeding to higher power levels.

3.1.8.6 A report covering single loop operation, permitted by Specification 3.1.8, shall be submitted within 90 days after completion of testing.

This report shall :include the data obtained together with analyses and interpretations of these data which demonstrate:

(1) Coolant flows in the idle loop and operating loop are as 26 predicted. 2 (2) Relative incore flux and temperature profiles remain es- I sentially the same as for four pump operation at each power level taking into account the reduced flow in single loop operation.

(3) Operating loop temperatures and flows are obtained which justify the revised safety system setting prescribed for the temperature and flow instruments located in the operating loop (which must sense the combined core flow plus the cooler bypass flow of the idle loop).

Subsequent single loop operation shall be contingent upon Commission approval.

Bases The purpose of single loop testing is to (1) supplement the 1/6 scale model test information, (2) verify predicted flow through the idle loop, (3) verify that changes in power level do not affect flow distribution or core power 3.1-19 S1975

clistribution, and (4) demonstrate that limiting safety system settings (pump monitor trip setpoint and reactor coolant outlet temperature trip setpoint) can be conservatively adjusted taking into account instrument errors.

Limiting the pump monitor trip setpoint to 50 percent uf rated power and the reactor coolant outlet temperature trip setpoint to 610°F to perform this con firmatory testing assures operation well within the core protective safety limits shown in Figure 2.1-3, Curve 2.

Incore thermocouples will be installed and data will be taken to check outlet core temperature profiles. These data will be used in evaluating test results.

4.2.3 The structural integrity of the Reactor Coolant System boundary shall be maintained at the level required by the original ac ceptance standards throughout the life of the station. Any evidence, as a result of the tests outline& in Table IS-261 of Section XI of the code, that defects have dcveloped or grown, shall be investigated, including evaluation of comparable areas of the Reactor Coolant System.

4.2.4 The results of the Inservice Inspections performed pursuant to

• 2 Specifications 4.2.1, 4.2.2, and 4.2.3 shall be reported to the 21 Commission within 90 days of completion. I*

4.2.5 To assure the structual integrity of the reactor internals through out the life of the unit, the two sets of main internals bolts (connecting the core barrel to the core support shield and to the lower grid cylinder) shall remain in place and under tension. This will be verified by visual inspection to determine that the welded bolt locking caps renain in place. All locking caps will be inspected after hot functional testing and whenever the internals are removed from the vessel during a refueling or maintenance shutdown. The core barrel to core support shield caps will be inspected each refueling shutdown.

4.2.6 Sufficient records of each inspection shall be kept to allow com parison and evaluation o. future inspections.

4.2.7 The inservice inspection program shall be reviewed at the end of five years to consider incorporation of new inspection techniques and equipment which have been proved practical and the conclusions of this review and evaluation shall be discussed with the NRC/ORI 4.2.8 At approximately three-year intervals, the bore and keyway of each reactor coolant pump flywheel shall be subjected to an in-place, volumetric examination. Whenever maintenance or repair activities necessitate flywheel removal, a surface examination of exposed surfaces and a complete volumetric examination shall be performed, if the interval measured from the previous such inspection is greater than 6 2/3 years.

4.2.9 For Unit 1 and Unit 2, a B Type vessel specimen capsule shall be withdrawn after one year of operation and an A Type capsule shall be withdrawn after 11, 17, and 22 years of operation. The with drawal schedules may be modified to coincide with those refueling outages or unit shutdowns most closely approaching the withdrawal schedule. Specimens thus withdrawn shall be tested in accordance with ASTU-E-185-70. For Unit 3, a B Type vessel specimen capsule shall be withdrawn after one year of operation and an A Type capsule shall be withdrawn after 7, 14, and 17 years of operation.

The withdrawal schedules may be modified to coincide with those refueling outages or unit shutdowns most closely approaching the withdrawal schedule. Specimens thus withdrawn shall be tested in accordance with ASTM-E-185-72. The results of these examinations 213 shall be reported to the Commission within 90 days of completion 21 of testing. *'

4.2-2 DEC0 2 297

• j 4.2.10 During the first two refueling periods, two reactor coolant system piping elbows shall be ultrasonically inspected along their longitudinal welds (4 inches beyond each side) for clad bonding and for cracks in both the clad and base metal. The elbows to be inspected are identified in B&W Report 1364 dated December 1970.

Bases The surveillance program has been developed to comply with Section XI of the ASME Boiler and Pressure Vessel Code, Inservice Inspection of Nuclear Reactor Coolant Systems, 1970, including 1970 winter addenda, edition. The program places major emphasis on the area of highest stress concentrations and on areas where fast neutron irradiation might be sufficient to change material properties.

The reactor vessel specimen sbrveillance program for Unit 1 and Unit 2 is based on equivalent exposure times of 1.8, 19.8, 30.6 and 39.6 years. The contents of the different type of capsules are defined below.

AType B Type Weld Material IIAZ Material HAZ Material Baseline Material Baseline Material For Unit 3, the Reactor Vessel Surveillance Program is based on equivalent exposure times of 1.8, 13.3, 26.7, and 30.0 years. The specimens have been selected and fabricated as specified in ASTM-E-185-72.

Early inspection of Reactor Coolant System piping elbows is considered desirable in order to reconfirm the integrity of the carbon steel base metal when explosively clad with sensitized stainless steel. If no degradation is observed during the two annual inspections, surveillance requirements will revert to Section XI of the ASME Boiler and Pressure Vessel Code.

Bases Provisions have been made for an in-service surveillan e program, covering the first several years of the life of the unit, intended to provide suf ficient evidence to maintain confidence that the integrity of the Reactor Building is being preserved. This program consists of tendon, tendon anchorage and liner plate surveillance.

To accomplish these programs, the following representative tendon groups have been selected for surveillance:

Horizontal - Three 1200 tendons comprising one complete hoop system below grade.

Vertical - Three tendons spaced approximately 1200 apart.

Dome - Three tendons spaced approximately 120 apart.

The inspection during this initial period of at least one wire from each of the nine surveillance tendons (one wire per group per inspection) is con sidered sufficient representation to detect the presence of any wide spread tendon corrosion or pitting conditions in the structure. This program will.

be subject to review and revision as warranted based on studies and on results obtained for this and other prestressed concrete reactor buildings during this period of time.

UNITED STATES NUCLEArv REGULATORY COMMISSION WASHINGTON, D. C. 20555 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION SUPPORTING AMENDMENT NO. i G TO FACILITY LICENSE" NO. DPR-38 CHANGE;NO.2 G TO TECHNICAL SPECIFICATIONS; AMENDMENT ýO. 1 G TO FACILITY LICENSE NO. DPR-47 CIHANGENO.2 I TO TECHNICAL SPECIFICATIONS; AMENDMHENT TO 1 ' TO FACILITY LICENSE NO. DPR-55 CHANGE NO.1 ,, TO TECHNICAL SPECIFICATIONS DUKE POWER COMPANY OCONEE NUCLEAR STATION, UNITS 1, 2, AND 3 DOCKET NOS. 50-269, 50-270, AND 50-287 Introduction By letter dated January 15, 1975, Duke Power Company (the licensee) requested a change in the Technical Specifications of Licenses No. DPR-38, DPR-47, and DPR-55 for the Oconee Nuclear Station, Units 1, 2, and 3. The proposed amendments would. modify the station reporting requirements and delete the definition of an abnormal occurrence.

Discussion The proposed changeswould be administrative in nature and are intended to provide uniform license requirements. In Section 208 of .the Energy Reorganization Act of 1974 "abnormal occurrences" is defined as an unscheduled incident or event which the Commission determines is significant from the standpoint of public health and safety. The term "abnormal occurrence" is reserved for usage by NRC. Regulatory Guide 1.16, "Reporting of Operating Information Appendix A Technical Specifications", Revision 4, enumerates required reports consistent with Section 208. The proposed change to required reports identifies the reports required of all licensees not already identified by the regulations and those unique to this facility.

The proposal would formalize present reporting and would delete any reports no longer needed for assessment of safety related activities.

Evaluation The new guidance for reporting operating information does not identify any event as an "abnormal occurrence." -T-he proposed reporting requirements also delete reporting of information no longer required and duplication of reported information. The standardization of required reports and desired format for the information will permit more rapid recognition of potential problems.

During our review of the proposed changes, we found that certain modi fications to the proposal were necessary to have conformance with the desired regulatory position. These changes were discussed with the licensee and have been incorporated into the proposal.

We have concluded that the proposal as modified improves the licensee's program for evaluating plant performance and the reporting of the operating information needed by the Commission to assess safety related activities and is acceptable. The modified reporting program is consistent with the guidance provided by Regulatory Guide 1.16, "Reporting of Operating Information - Appendix A Technical Specifications",

Revision 4.

Conclusion We have concluded, based on the considerations discussed above, that:

(1) because the change does not involve a significant increase in the probability or consequences of accidents previously consider~d and does not involve a significant decrease in a safety margin, the change does not involve a significant hazards consideration, (2) there is reasonable assurance that thehealth and safety of the public will not be endangered by operation in the proposed manner, and (3) such activities will be conducted in compliance with the Commission's regulctions and the issuance of this amendment will not be inimical to the common defense and security or to the health and safety of the public.
