j TECHNICAL EVALUATION REPORT ON THE SECOND 10-YEAR INTERVAL INSERVICE INSPECTION PROGRAM PLAN:

FLORIDA POWER CORPORATION, CRYSTAL RIVER NUCLEAR PLANT, UNIT 3 DOCKET NUMBER 50-302

1. INTRODUCTION Throughout tha serv 4ce life of a water cooled nuclear power facility, 10 CFR 50.55a(g)(4) (Reference 1) requires that components (including supports) that are classified as American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code Class 1, Class 2, and Class 3 meet the requirements, except the design and access provisions and tre preservice examination requirements, set forth in the ASME Code section XI, Rules for Inser1 ice inspection of Nuclear Power Plant Components (Reference 2), to the extent practical within the limitations of design, geometry, and materials of construction of the components. This section of the regulations also requires that inservice examinations of components and system pressure tests conducted during successive 120-month inspection intervals shall comply with the requirements in the latest editior, and addenda of the Code incorporated by reference in 10 CFR 50.55a(b) on the dtte 12 months prior to the start of the 120 month inspection iriterval, sub'ect to the limitations and modifications listed therein. The components (including supports) may meet requirements set forth in subsequent editions and addenda of this Code that are incorporated by reference in 10 CFR 50.55a(b) subject to the limitations and modifications listed therein. The Licensee, Florida Power Corporation, has prepared the Crystal River Nuclear Plant, Unit 3, Second 10 Year interval inservice Inspection (ISI) Program Plan, to meet the requirements of the 1983 Edition, Summer 1983 Addenda (83S83) of the ASME Code Section XI, except that the extent af examination of certain Code Class 1 and Code Class 2 piping welds has been determined by the 1974 Edition, Summer 1974 Addenda as permitted and required by 10 CFR 50.55a(b). The Second 10-year interval began March 14, 1987 and ends March 13, 1997.

As required by 10 CFR 50.55a(g)(5), if the licensee determines that certain Code examination requirements are impractical and requests relief from them,

I the licensee shall submit information and justifications to the Nuclear Regulatory Commission (NRC) to support that determination.

Pursuant to 10 CFR 50.55a(g)(6). the NRC will evaluate the licensee's determination that Code requirements are impractical to implement.

Alternatively, pursuant to 10 CFR 50.55a(a)(3), the NRC will evaluate 'he Licensee's determination that either (i) the proposed alternatives provide an l acceptable level of quality and safety or that (ii) Code compliance would result in hardship or unusual difficulty without a compensating increase in  ;

safety. The NRC may grant relief and may impose alternative requirements that are determined to be authorized by law, will not endanger life or property or the common defense and security, and are otherwise in the public interest, giving due consideration to the burden upon the licensee that could result if the requirements were imposed on the facility.

The information in the Crystal River Nuclear Plant, Unit 3 Second 10 Year Interval ISI Program Plan, (Reference 3), submitted February 9, 1988, was reviewed, including the requests for relief from the ASME Code Section XI requirements that the Licensee has determined to be impractical.

Supplemental ISI information was received in a letter dated May 25, 1990 (Reference 4). Review was also completed on letters to the Licensee dated ,

April 19, 1988 (Reference 5) and September 28, 1988 (Reference 6) regarding Requests for Relief Nos.88-010, 88 030 and 88-040, and NRC Safety Evaluation  :

Reports (SERs) dated May 26, 1987 (Reference 7), May 30, 1990 (Reference 8) and September 13, 1991 (Reference 9).

The review of the ISI Program Plan was performed using the Standard Review

- Plans of NUREG 0800 (Reference 10), Section 5.2.4, " Reactor Coolant Boundary Inservice Inspections and Testing," and Section 6.6, " Inservice Inspection of Class 2 and 3 Components."

In a letter dated April 25, 1991 (Reference 11), the NRC requested additional information that was required in order to complete the review of the ISI Program Plan. The requested information was provided by the Licensee in the

" Response to Request for Information Related to the Inservice inspection Program Plan" dated June 7, 1991 (Reference 12).

- on the starting date of March 14, 1987, the Code applicable to the ,

second interval 151 program is the 1983 Edition, Summer 1983 Addenda.

As stated in Section 1 of this report, the Licensee has prepared the Crystal River Nuclear Plant, Unit 3, Second 10 Year ISE Program Plan to meet the requirements of 1983 Edition, Summer 1983 Addenda of the Code, except that the extent of examination for Class 1, Examination Category B J, and Class 2. Examination Category C-F and C G welds in the Residual Heat Removal (RHR), Emergency Core Cooling (ECC), and 2 Containment Heat Removal (CHR) systems has been determined by the requirements of the 1974 Edition through Summer 1975 Addenda (74575) as permitted and required by 10 CFR 50.55a(b).

2.2.2 Acceotability of the Exa,mination Samele Inservice volumetric, surface, and visual examinations shall be performed on ASME Code Class 1, 2, and 3 components and their supports using sampling schedules described in Section XI of the ASME Code and 10 CFR 50.55a(b).

In the NRC request for additional information, the Licensee was requested to confirm that a representative sampling of welds was being examined in the Reactor Building Spray System (RBS) (equivalent to CHR at Crystal River, Unit 3) during the second 10-year inspection interval , in a letter dated June 7,.1991 (Reference 12), the Licensee committed to performing volumetric examinations of 7.5% of the welds in the RBS system during the subject interval.

Based on the review of the Crystal River, Unit 3, Second 10-year l Interval 151 Program Plan and the commitment to perform augmented volumetric examinations on the RSS system, it has been determined

that sample size and weld selection have been implemented in 5

i accordance with the Code and 10 CFR 50.55a(b) and appear to be correct.

2.2.3 Exclusion Criteria ,

The criteria used to exclude components from examination shall be

. consistent with Paragraphs IWB 1220, IWC 1220, IWC 1230, !WD 1220, and 10 CFR 50.55a(b). With the commitments made by the Licensee in the June 7, 1991 submittals (Reference 12) in response to the NRC 4 concerns regarding the exclusion of the RBS system, the exclusion criteria have besn applied by the Licensee in accordance with the Code as discussed in the 151 Program Plan, and app?ar to be correct.

2.2.4 Auamented Examination Commitments L

in addition to the requirements as specified in Section XI of the ASME Code, the Licensee has committed to perform the following augmented examinations:

(a) The reactor pressure vessel will be examined to the requirements ,

of Regulatory Guide 1.150, Ultrasonic Testing of Reactor Vessel Welds During Preservice and inservice Examination, Revision 1 (Reference 13);

4. CONCLUSION Pursuant to 10 CFR 50.55a(g)(5) or, alternatively,10 CFR 50.55a(a)(3), it has been determined that certain inservice examinations cannot be performed to the extent required by Section XI of the ASME Code. in these cases for which

. relief is requested, the Licensee has demonstrated that specific Section XI requirements are impractical. Request for Relief No.90-010 was previously granted in a NRC SER dated May 30, 1990. Request for Relief Nos.88-030 and 88-040 were previously granted in a [[letter::3F0988-17, Forwards Review Summary Re Relationship Between Ser,B&W Owners Group Generic ATWS Design & Util Conceptual Design,As Requested in NRC .Rept MAR 84-06-07-01, ATWS Conceptual Design Also Encl|letter dated September 28, 1988]]. Request for Relief No.88-010 was previously granted in a letter dated April 19, 1988.

Request for Relief Nos.90-020, 90-050 and 90-060 were previously granted in a NRC SER dated September 13, 1991. No new relief requests were evaluated in this report.

The Licensee should continue tc monitor the development of new or improved examination techniques. As improvements in these areas are achieved, the Li",ensee should incorporate these techniques in the ISI program plan examination requirements.

Based on the review of the Crystal River Nuclear Plant, Unit 3, Second 10-Year Interval inservice inspection Program Plan, the Licensee's response to the NRC's Request for Additional Information, and the recommendations for granting -

relief from the ISI examination requirements that have been determined to be impractical, it is concluded that the Crystal River Nuclear Plant, Unit 3, Second 10 Year Interval inservice Inspection Program Plan, is acceptable and in compliance with 10 CFR 50.55a(g)(4).
