1.0 INTRODUCTION

l l The Code of Federal Regulations,10 CFR 50.55a, requires that inservice l

testing (IST) of certain ASME Code Class 1, 2, and 3 pumps and valves be performed in accordance with Section XI of the ASME Boiler and Pressure Vessel Code and applicable addenda, except where alternative: are authorized or relief is granted by the Comission pursuant to 10 CFR 50.55a(a)(3)(1),

(a)(3)(ii), or (f)(6)(i). In order to obtain authorization or relief, the I licensee must demonstrate that: (1) the proposed alternatives provide an acceptable level of quality and safety, (2) compliance would result in hardship or unusual difficulty without a compensating increase in the level of quality and safety, or (3) compliar.ce is impractical for its facility.

i Section 50.55a(f)(4)(iv) provides that IST of pumps and valves may meet the requirements set forth in subsequent editions and addenda that are incorporated by reference in paragraph (b) of 50.S5a, subject to the limitations and modifications listed, and subject to Comission approval. The NRC guidance contained in Generic Letter (GL) 89-04, " Guidance on Developing Acceptable Inservice Testing Programs," provided alternatives to the Code requirements determined to be acceptable to the staff.

Section 50.55a authorizes the Comission to approve alternatives or grant relief from ASME Code requirements upon making the necessary findings. The NRC staff's findings with respect to relief requested and alternatives proposed as part of the licensee's IST program are contained in this safety evaluation (SE). A brief description of each relief request (RR) and a sumary of the staff's conclusion on each request is provided in Table 1, "Sumary of Relief Requests." Attachment I to this enclosure provides a sumary that compares the staff's conclusions following its review of the licensee's second interval IST program (as modified by the licensee's response to NRC GL 89-04 dated October 3, 1989, see NRC SE dated May 13, 1992) to the licensee's third interval IST program submittal dated November 30, 1992. It also provides a status of each item including any remaining action that needs to be taken by the licensee. Enclosure 2 is the technical evaluation report (TER) prepared by EG&G Idaho, Inc. (EG&G).

The IST program addressed herein covers the third ten-year inspection interval which will begin on September 1, 1993, (NOTE: The licensee should indicate the interval dates in the IST Program document). A request for extension of the second ten-year interval from November 1992 to August 31, 1993, was included in the licensee's November 30, 1992, submittal (RR-01). The staff 9309150171 930903 PDR ADOCK 05000271 P PDR ,

i j

responded to RR-01 in a letter dated April 6, 1993, indicating the

! acceptability of the extension in accordance with provision of ASME Code, ,

Section XI, IWA-2430.

l The Vermont Yankee (VY) IST program is based on the requirements of the 1989 i

! Edition of Section XI, Division 1, of the ASME Code Boiler and Pressure Vessel Code and 10 CFR 50.55a. In accordance with Articles IWP-1000 and IWV-1000 and

Table IWA-1600-1 of the 1989 Edition of Section XI and 10 CFR 50.55a(b)(2) l (viii), the pump and valve testing requirements were based on the ASME/ ANSI CMa-1988 Addenda to ASME/ ANSI OH-1987. The NRC approved the use of the later i Edition of the Code pursuant to 10 CFR 50.55a(f)(4)(iv) in a letter to the

! licensee dated September 2, 1992. The additional requirements described in 10 i CFR 50.55a(b)(2)(vii) and the recommendations described in GL 89-04 and its

supplements are also included as applicable, i

j 2.0 EVALUATION ,

The licensee's requests for rclief from the requirements of Section XI have 1

been reviewed by the staff with the assistance of its contractor, EG&G. The

. TER, provided as Enclosure 2, is EG&G's evaluation of the licensee's IST

] program RR. The staff has reviewed the TER and concurs with, and adopts, the evaluations and conclusions with the modifications noted below. Table 1,

"Sumary of Relief Requests," provides a brief description of each of the l licensee's proposed RR as well as a sumary of the staff's conclusion on each

, request. A summary of the staff's findings on Vermont Yankee Nuclear Power j Corporation's response to the NRC's IST SE dated May 13, 1992, is included as l Enclosure I to this SE. The granting of relief or authorization of proposed j alternatives is based upon the fulfillment of any commitments made by the licensee in its basis fer each RR and the alternatives proposed. The j implementation of IST program is subject to inspection by NRC.

The licensee should refer to Appendix A of the TER for a discussion of IST program anomalies identified during the review. The licensee should provide

the NRC with a written response to each anomaly within 1 year of the date of j this SE or by the end of the next refueling outage, whichever is longer. The j necessary actions to address the anomalies should be included in the j licensee's third ten-year interval updated program for the interval to begin 1 on September 1, 1993, to the degree the concerns are applicable to the updated j Code requirements. The updated program should be provided to the NRC and

implemented as soon as possible. The reviews performed by the staff do not

ensure that all components are included and that all testing is appropriately applied; rather, these areas are subject to periodic NRC inspection.

3.0 RELIEF RE00EST V-05 (TER Section 3.10.1.11  !

i In V-05, the licensee requested relief from the requirements of OM-1-1987,

" Requirements for Inservice Performance Testing of Nuclear Power Plant i Pressure Relief Devices." Specifically, the licensee proposed to replace one-i half of their main steam safety valves with a complement of pretested valves.

i The proposal would also permit power generation to resume prior to obtaining j test as-found data and the sample size would not be expanded based on test q failures.

l

i

, i 1 OH-1-1987, paragraph 1.3.3.l(c) requires that the set pressure of the valves  ;

! whici. were removed be tested prior to resumption of electric power generation. i i

lf a full complement of pretested valves are installed, the set pressure test l of the removed valves is required to be completed within 12 mnnths of removal l trom ;he system.

I j The TER recomended that the licensee be granted interim relief (i.e., until

the refueling outage following the August 1993 refueling outage) from the valve testing and sample expansion requirements of the Code pursuant to 10 CFR 50.55a(f)(6)(i). "During the August 1993 refueling outage, if one of

. these valves fails a test, the licensee should expeditiously perform the j required root cause analysis to determine if there could be a comon mode or >

generic failure concern. If it is determined that the cause of the test j failure is generic or common with the other group valves, the remaining valves l should be imediately be tested, even if this requires a plant shutdown. In l

! the interim, the licensee should assess the testing requirements for these j valves. The assessment may include TS changes and Code inquiries."

! The NRC staff is granting the licensee interim relief, as recomended in the i TER, with the following modified provisions. The valves removed during the

August 1993 refueling outage should be set pressure tested within 6 months of the resumption of electric power generation. If the as-found set pressure of any of these valves exceeds the acceptance criteria of OM-1-1987, Paragraph ,

1.3.3.l(d), a root cause determination (i.e., addressing why the "as-found" l 4

set pressure exceeded 3% of the stamped set pressure) should be made on each  !

valve that failed to meet the acceptance criteria as soon as possible but at a least within 30 days. If the cause could affect the remaining valves, which  !

would require increasing the test sample, verification of the set pressere for

, additional valves will be required to be performed in accordance with OM-1 '

s requirements, even if the unit must shut down to complete the test. That is, 1 if the removed valves are set pressure tested, and if one or more valves  ;

exceeds the stamped set pressure criteria by 3% or greater, Paragraph j 1.3.3.l(e)(1) requires testing of additional valves. If a shutdown is I i required, it should be conducted consistent with the provisions of Technical l

! Specification 3.6.D.2. Alternatively, the licensee may attempt to justify to

the NRC not testing additional valves (and continued plant operation) based on j the results of tia set pressure tests, overpressure protection analysis, and j root cause analysis. I J

Even th'ough the VY Technical Specifications require the set pressure to be l i within 1% of the specified set pressure, testing of additional valves is not i l required per OM-1-1987 unless the set pressure is exceeded by 3% or greater. l Based on the performance history of the valves at VY, it does not appear that l the valves have experienced significant setpoint drift; therefore, the

likelihood of one or more valves exceeding the set pressure by 3% or greater j is not high. Prior to the next refueling outage following the August 1993

{ refueling outage, the licensee should review all the applicable testing requirements for these valves, pursue various methods of meeting the

requirements for testing the removed valves prior to resumption of electric

power generation, ensure compliance with state boiler code requirements (if J l

1 I

. I applicable), and, if needed, request guidance on the intent of the OM-1-1987 requirement from the OEM Code committee. The interim relief will no longer l apply 'Jter the August 1993 refueling outage. For subsequent outages, the ,

licenste must comply with the Code requirements.

4.0 CONCLUSION

In evaluating the licensee's requests for relief from the requirements of Section XI, the staff considered: (1) whether proposed alternative testing a provides an acceptable level of quality and safety, (2) whether the hardship  ;

of compliance is without a compensating increase in safety, and (3) the l j impracticality of performing the required testing considering the burden if  ;

the requirements were imposed. The last column of Table 1 identifies the

! regulations under which the requests are approved. The staff has authorized alternatives pursuant to 10 CFR 50.55t(a)(3) and has determined that granting i

relief pursuant to 10 CFR 50.55a(f)(6)(i) is authorized by law and will not endanger life or property, or the common defense and security and is otherwise in the public interest. The granting of relief or authorization of proposed alternatives is based upon the fulfillment of any commitments made by the licensee in its basis for each relief request and the proposed alternate J

testing.  ;
