When a licensee determines that an inservice inspection requirement is | |||

- 1. Scoce/ Status of Review The Nuclear Regulatory Commission (NRC) is responsible for the review
! and disposition of licensee requests relating to inservice inspection
! requirements contained in the Code of Federal Regulations (CFR)
, 10 CFR 50.55a, and Section XI of the American Society of Mechanical l Engineers' (ASME), Boiler and Pressure Vessel Code. When submitting such requests, licensees are required to provide both a regulatory basis (by citing the appropriate section of 10 CFR 50.55a), and a technical discussion, supporting the request. This information is used in evaluating the request.
The staff has reviewed the available information in the Wolf Creek Generating Station, Second 10-Year Interval inservice Inspection Program Plan, the proposed alternatives to, and requests for relief from, ASME Code Section XI requirements, and additional information submitted by letters dated August 30, 1995 and May 3, 1996.
- 2. Additional Information Reauired i
The staff has concluded that additional information and/or clarification is required to complete the evaluation. The licensee must state the specific paragraph of the regulations (10 CFR 50.55a) under which the request is submitted and provide supporting justification as discussed below.
The regulations provide that a licensee may propose an alternative to I CFR or Code requirements in accordance with 10 CFR 50.55a(a)(3)(i) or 10 CFR 50.55a(a)(3)(ii). Pursuant to 10 CFR 50.55a(a)(3)(i), the proposed j alternative must be shown to provide an acceptable level of quality and safety, i.e., essentially, be equivalent to the original requirement in terms of quality and safety. Pursuant to 10 CFR 50.55a(a)(3)(ii), the licensee must show that compliance with the original requirement results in a hardship or unusual difficulty without a compensating increase in the level of quality and safety. Examples of hardship and/or unusual ;
difficulty include, but are not limited to, excessive radiation exposure, disassembly of components solely to provide access for examinations, and development of sophisticated tooling that would result in only minimal increases in examination coverage.

o A licensee may also submit a request for relief from ASME requirements.
In accordance with 10 CFR 50.55a(g)(5)(iii), if a licensee determines 4 that conformance with certain Code requirements is impractical for its facility, the licensee shall notify the Commission and submit, as !
specified in 10 CFR 50.4, information to support that determination.
When a licensee determines that an inservice inspection requirement is
, impractical, e.g., the system would have to be redesigned, or a ,
l component would have to be replaced to enable inspection, the licensee should cite 10 CFR 50.55a(g)(5)(iii). The NRC may, giving due consideration to the burden placed on the licensee, impose an alternative examination requirement.
The staff has concluded that the following specific information and/or clarification is required to complete the review of the ISI Program Plan:
A. Requests 12R-01, 12R-03, 12R-04, 12R-05, 12R-06, 12R-07, 12R-08, l and 12R-18, were submitted pursuant to 10 CFR 50.55a(a)(3)(ii). '
However, the bases for these requests mention " acceptable levels of quality and safety" and " examinations performed to the extent practical . " It is unclear as to which paragraph of 10 CFR 50.55a these requests should be evaluated against. Provide appropriate references to the Code of Federal Regulations and clarify the supporting bases for the subject requests.
B. Requests I2R-14, 12R-19, and I2R-20, were submitted without reference to a section of the Code of Federal Regulations.
Without these references, the subject requests cannot be evaluated. Provide appropriate references to the Code of Federal Regulations and clarify the supporting bases for the subject requests.
