SUMMARY
DESCRIPTION This letter is a request to amend Operating Licenses DPR-80 and DPR-82 for Units 1 and 2 of the Diablo Canyon Power Plant (DCPP), respectively.
The proposed changes would revise the Operating Licenses by incorporating the attached change into the DCPP Unit 1 and 2 Technical Specifications (TS).The proposed changes would revise TS 5.5.16, "Containment Leakage Rate Testing Program," for DCPP Units 1 and 2. The proposed changes are based on the NRC-approved Technical Specifications Task Force (TSTF) Improved Standard Technical Specifications Change Traveler 343, Revision 1, "Containment Structural Integrity," (TSTF-343).
The proposed changes are consistent with the wording in section 5.5.16 of NUREG-1431, Revision 3.1, "Standard Technical Specifications, Westinghouse Plants," (STS), since STS has already incorporated TSTF-343.
The proposed change revises TS 5.5.16, "Containment Leakage Rate Testing Program," for consistency with the requirements of 10 CFR 50.55a(g)(4) for components classified as Code Class CC. This regulation requires licensees to update their containment inservice inspection requirements in accordance with Subsections IWE and IWL of Section XI, Division I of the ASME Boiler and Pressure Vessel Code as limited by 10 CFR 50.55a(b)(2)(vi) and modified by 10 CFR 50.55a(b)(2)(viii) and 10 CFR 50.55a(b)(2)(ix).
The proposed change also revises the TS Bases for Surveillance Requirement (SR) 3.6.1.1. The TS Bases for SR 3.6.1.1 is revised for consistency with the requirements of the ASME Code Section XI, Subsection IWL, and applicable addenda as required by 10 CFR 50.55a.As a result of this change, DCPP will be required to perform fewer visual inspections of the containment during the ten year interval.
However, the requirements for inspection in Subsection IWE and IWL of Section XI are more rigorous than those currently required to be performed.
1 Enclosure 1 PG&E Letter DCL-06-142 2.0, DETAILED DESCRIPTION 2.1 Proposed Changes The proposed change would revise TS 5.5.16 to add the following exceptions to Regulatory Guide 1.163, "Performance-Based Containment Leak-Testing Program," 1. The visual examination of containment concrete surfaces intended to fulfill the requirements of 10 CFR 50, Appendix J, Option B testing, will be performed in accordance with the requirements of and frequency specified by ASME Section Xl Code, Subsection IWL, except where relief has been authorized by the NRC.2. The visual examination of the steel liner plate inside containment intended to fulfill the requirements of 10 CFR 50, Appendix J, Option B testing, will be performed in accordance with the requirements of and frequency specified by ASME Section XI Code, Subsection IWE, except where relief has been authorized by the NRC.The TS Bases for SR 3.6.1.1 are revised for consistency with the requirements of the ASME Code Section XI, Subsection IWL, and applicable addenda as required by 10 CFR 50.55a. The TS Bases changes are included for information only.The proposed TS changes are noted on the marked-up TS page provided in Enclosure
- 2. The proposed retyped TS pages are provided in Enclosure
- 3. The revised TS Bases pages are provided for information only in Enclosure 4.2.2 Background On January 7, 1994, the Nuclear Regulatory Commission (NRC) published a proposed amendment to the regulations to incorporate by reference the 1992 Edition with the 1992 Addenda of Subsections IWE and IWL of Section XI, Division I of the ASME Boiler and Pressure Vessel Code (the Code). The final rule, Subpart 50.55a(g)(6)(ii)(B) of Title 10 of the Code of Federal Regulations (10 CFR), became effective on September 9, 1996, and required licensees to implement Subsections IWE and IWL, with specified modifications and limitations, by September 9, 2001.2 Enclosure 1 PG&E Letter DCL-06-142 The containment structure is a steel lined, reinforced concrete structure.
It consists of a vertical cylindrical structure with a hemispherical dome.3.0 TECHNICAL EVALUATION 3.1 Containment Design Basis The TS requirements for the Containment Leakage Rate Testing Program specify that the program shall be in accordance with the guidelines contained in Regulatory Guide 1.163. Regulatory Position C.3 of the regulatory guide states that "Section 9.2.1, 'Pretest Inspection and Test Methodology,'
of NEI 94-01 provides guidance for the visual examination of accessible interior and exterior surfaces of the containment system for structural problems.
These examinations should be conducted prior to initiating a Type A test, and during two other refueling outages before the next Type A test if the interval, for the Type A test has been extended to 10 years, in order to allow for early uncovering of evidence of structural deterioration." There are no specific requirements in NEI 94-01 for the visual examination except that it is to be a general visual examination of accessible interior and exterior surfaces of the primary containment components.
In addition to the requirements of Regulatory Guide 1.163 and NEI 94-01, the concrete surfaces of the containment must be visually examined in accordance with the ASME Section XI Code, Subsection IWL, and the liner plate inside containment must be visually examined in accordance with Subsection IWE. The frequency of visual examination of the concrete surfaces per Subsection IWL is once every five years alternating between units for a 2-unit plant, and the frequency of visual examination of the liner plate per Subsection IWE is, in general, three visual examinations over a 10-year period. The visual examinations performed pursuant to Subsection IWL may be performed at any time during power operation or during shutdown, and the visual examinations performed pursuant to Subsection IWE are performed during refueling outages since this in the only time that the liner plate is fully accessible.
3.2 Containment Safety Analysis Basis The visual examinations performed pursuant to Subsections IWL and IWE are more rigorous than those performed pursuant to Regulatory Guide 1.163 and NEI 94-01. For example, Subarticle IWE-2320 requires the general visual examination to be the responsibility of an individual who is knowledgeable in the requirements for design, inservice inspection, and testing of Class MC and metallic liners of Class CC components.
3 Enclosure 1 PG&E Letter DCL-06-142 Subsection IWE, Subarticle-2330 requires the examination to be performed either directly or remotely, by an examiner with visual acuity sufficient to detect evidence of degradation.
Similarly, Subarticle IWL-2320 states that: "The Responsible Engineer shall be a Registered Professional Engineer experienced in evaluating the inservice condition of structural concrete.
The Responsible Engineer shall have knowledge of the design and Construction Codes and other criteria use in design and construction of concrete containments in nuclear power plants.The Responsible Engineer shall be responsible for the following: (a) development of plans and procedures for examination of concrete surfaces;(b) approval, instruction, and training of concrete examination personnel;(c) evaluation of examination results;(d) preparation or review of Repair/Replacement Plans and procedures;(e) review of procedures for pressure tests following repair/replacement procedures;(f) submittal of report to the Owner documenting results of examinations and repairs." Based on the above, the Responsible Engineer will ensure that a comprehensive visual examination of the concrete is performed in accordance with Code requirements except where relief has been granted by the NRC. Furthermore, with respect to examinations performed pursuant to both Subsections IWL and IWE, visual examinations of both the concrete surfaces and the liner plate must be reviewed by an Inspector employed by a State or municipality of the United States or an Inspector regularly employed by an insurance company authorized to write boiler and pressure vessel insurance, in accordance with IWA-2110 and IWA-2120.The combination of the Code requirements for the rigor of the visual examinations plus the third party review will more than offset the fact that fewer visual examinations of the concrete will be performed during a 10-year interval.
The fact that the concrete visual examination pursuant to Subsection IWL may be performed during power operation as opposed to during a refueling outage will have no effect on the quality of the examination and will provide flexibility in scheduling of the visual examinations.
4 Enclosure 1 PG&E Letter DCL-06-142 4.0 REGULATORY ANALYSIS 4.1 No Significant Hazards Consideration Pacific Gas and Electric Company (PG&E) has evaluated whether or not a significant hazards consideration is involved with the proposed amendment by focusing on the three standards set forth in 10 CFR 50.92, "Issuance of amendment," as discussed below: 1. Does the proposed change involve a significant increase in the probability or consequences of an accident previously evaluated?
Response:
No.The proposed change revises the Technical Specification (TS)administrative controls programs for consistency with the requirements of 10 CFR 50, paragraph 55a(g)(4) for components classified as Code Class CC.The proposed change affects the frequency of visual examinations that will be performed for the concrete surfaces of the containment for the purpose of the Containment Leakage Rate Testing Program.In addition, the proposed change allows those examinations to be performed during power operation as opposed to during a refueling outage. The frequency of visual examinations of the concrete surfaces of the containment and the mode of operation during which those examinations are performed has no relationship to or adverse impact on the probability of any of the initiating events assumed in the accident analyses.
The proposed change would allow visual examinations that are performed pursuant to NRC approved ASME Section Xl Code requirements (except where relief has been granted by the NRC) to meet the intent of visual examinations required by Regulatory Guide 1.163, without requiring additional visual examinations pursuant to the Regulatory Guide. The intent of early detection of deterioration will continue to be met by the more rigorous requirements of the Code-required visual examinations.
As such, the safety function of the containment as a fission product barrier is maintained.
The proposed change does not impact any accident initiators or analyzed events or assumed mitigation of accident or transient events. It does not involve the addition or removal of any equipment, or any design changes to the facility.5 Enclosure I PG&E Letter DCL-06-142 Therefore, the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.
- 2. Does the proposed change create the possibility of a new or different accident from any accident previously evaluated?
Response:
No.The proposed change revises the TS Administrative Controls programs for consistency with the requirements of 10 CFR 50, paragraph 55a(g)(4) for components classified as Code Class CC.The change affects the frequency of visual examinations that will be performed for the concrete surfaces of the containments.
In addition, the proposed change allows those examinations to be performed during power operation as opposed to during a refueling outage.The proposed change does not involve a modification to the physical configuration of the plant (i.e., no new equipment will be installed) or a change in the methods governing normal plant operation.
The proposed change will not impose any new or different requirements or introduce a new accident initiator, accident precursor, or a malfunction mechanism.
Additionally, there is no change in the types or increases in the amounts of any effluent that may be released off site and there is no increase in individual or cumulative occupational exposure.Therefore, the proposed change does not create the possibility of a new or different kind of accident from any accident previously evaluated.
- 3. Does the proposed change involve a significant reduction in a margin of safety?Response:
No.The proposed change revises the TS Administrative Controls programs for consistency with the requirements of 10 CFR 50, paragraph 55a(g)(4) for components classified as Code Class CC.The change affects the frequency of visual examinations that will be performed for the concrete surfaces of the containments.
In addition, the proposed change allows those examinations to be performed 6 Enclosure 1 PG&E Letter DCL-06-142 during power operation as opposed to during a refueling outage.The safety function of the containment as a fission product barrier will be maintained.
Therefore, the proposed change does not involve a significant reduction in a margin of safety.Based on the above evaluation, PG&E concludes that the proposed change presents a no significant hazards consideration under the standards set forth in 10 CFR 50.92(c), and accordingly, a finding of "no significant hazards consideration" is justified.
4.2 Applicable Regqulatory Requirements/Criteria The regulatory basis for Pressurized Water Reactor Improved Standard Technical Specification (ISTS) 3.6.1, "Containment," is to ensure that the containment is capable of remaining leak-tight following a loss of coolant accident.
This ensures that offsite radiation exposures are maintained within the limits of 10 CFR 100.10 CFR 50, Appendix A, General Design Criterion 16, "Design," requires that reactor containment and associated systems shall be provided to establish an essentially leak-tight barrier against the uncontrolled release of radioactivity to the environment and to assure that the containment design conditions important to safety are not exceeded for as long as the postulated accident conditions require.This change will not reduce the leak-tightness of the containment.
4.3 Conclusions In conclusion, based on the considerations discussed above, (1)there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2)such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.5.0 ENVIRONMENTAL CONSIDERATION PG&E has evaluated the proposed amendment and has determined that it does not involve (i) a significant hazards consideration, (ii) a significant change in the types or significant increase in the amounts of any effluents 7 Enclosure 1 PG&E Letter DCL-06-142 that may be released offsite, or (iii) a significant increase in individual or cumulative occupational radiation exposure.
Accordingly, the proposed amendment meets the eligibility criterion for categorical exclusion set forth in 10 CFR 51.22(c)(9).
Therefore, pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the proposed amendment.

The visual examinations of the steel liner plate inside containment are performed during maintenance or refueling outages since this is the only time the liner plate is fully accessible.
2 Containment B 3.6.1 BASES (continued)
APPLICABILITY In MODES 1, 2, 3, and 4, a DBA could cause a release of radioactive material into containment.
In MODES 5 and 6, the probability and consequences of these events are reduced due to the pressure and temperature limitations of these MODES. Therefore, containment is not required to be OPERABLE in MODE 5 to prevent leakage of radioactive material from containment.
The requirements for containment during MODE 6 are addressed in LCO 3.9.4,"Containment Penetrations." ACTIONS A.1 In the event containment is inoperable, containment must be restored to OPERABLE status within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />. The 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> Completion Time provides a period of time to correct the problem commensurate with the importance of maintaining containment during MODES 1, 2, 3, and 4. This time period also ensures that the probability of an accident (requiring containment OPERABILITY) occurring during periods when containment is inoperable is minimal.B.1 and B.2 If containment cannot be restored to OPERABLE status within the required Completion Time, the plant must be brought to a MODE in which the LCO does not apply. To achieve this status, the plant must be brought to at least MODE 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and to MODE 5 within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />. The allowed Completion Times are reasonable, based on operating experience, to reach the required plant conditions from full power conditions in an orderly manner and without challenging plant systems.SURVEILLANCE REQUIREMENTS SR 3.6.1.1 "" JR"T /-Maintaining the containment OPERABLE requires compliace with the visual examinations and leakage rate test requirements a specified in the Containment Leakage Rate Testing Program (Ref. 1). Failure to meet air lock and purge valve with resilient seal leakage limits specified in the LCO 3.6.2 and LCO 3.6.3 does not invalidate the acceptability of these overall leakage determinations unless their contribution to overall Type A, B, and C leakage causes that to exceed limits. As left leakage prior to the first startup after performing a required Containment Leakage Rate Testing Program leakage test is required to be < 0.6 La for combined Type B and C leakage and < 0.75 La for overall Type A leakage. At all other times between required leakage rate tests, the acceptance criteria is based on an overall Type A leakage limit of _< 1.0 La. At < 1.0 La the offsite dose consequences are bounded by the assumptions of the safety analysis.
