ENCLOSURE 2 Appendix 110-1 JAN 1 1 1979 SEISMIC QUALIFICATION REVIEW TEAM (SQRT)
Interim Procedures
- 1. SCOPE SQRT tasks include both generic and site specific reviews. Generic reviews cover equipment supplied by the NSSS and A/E connon to more than one plant.
-Specific plant reviews as delineated in the Standard Review Plan Sections 3.9.2 and 3.10 will be.supplemented by SQRT site visits and evaluation.
II. OBJECTIVES SQRT is a group of NRC staff members established to conduct reviews of the design adequacy of safety related mechanical components, instrumentation and control equipment, and their supporting structures for various vibratory loads. SQRT is charged with accomplishing the following three tasks.
- 1. Determine the design adequacy of mechanical and electrical components and their supports for the required vibratory loading conditions which include:
(a) Seismic (b) hydrodynamic (as applicable)
(c) explosive (as applicable)
(d) other vibratory inputs from the operating environment (as applicable)
(e) appropriate combinations of the above events.
- 2. Chances in sesmic qualification criteria, such as the revision of
.IEEE Std. 344 and other IEEE Standards, and the issuance of Regula tory Guides 1.100 and 1.89 require that the staff verify:
(a) For older plants having components qualified by previous criteria; that components have adequate margin to perform their intended design functions during and after a seismic event.
(b) For new plant applications; that there has been uniformity and consistency in implementing the current criteria.
- 3. In the case of plants which have design basis seismic ground motion levels and/or other required vibratory loads increased, review to assure adequate design margin exists at the revised levels.
III.
GENERAL CRITERIA The bases used by the staff to determine the acceptability of equipment qualification will be IEEE Std. 344-1975 as supplemented by Regulatory Guides 1.100 and 1.92, and Standard Review Plan Sections 3.9.2 and 3.10 IV. GENERAL PROCEDURES SQRT will conduct generic and plant specific reviews:
- 1. Generic reviews will be conducted of all NSSS vendors and most architect engineers (major'equipment vendors and testing laboratories may be included if necessary) to assure proper interpretation and.
implementation of the current equipment qualification criteria applied
- JAN 1 1 1979 to plants applying for construction permits and operating licenses.
- 2. A plant specific equipment qualification review will be conducted of each plant now undergoing licensing review having components qualified to criteria different from current requirements.
A. For components having multi-plant application (such as those within the scope of an NSSS vendor), an equipment qualification review at specific sites will provide generic qualifications.
B. For components which have only specific plant application (mostly those within the scope of the BOP supply), an -equipment qualification review at specific sites will provide site-specific qualifications.
- 3. Equipment qualification review for plants with revised increased design basis seismic ground motion levels and/or other required vibratory loads will be conducted on a plant by plant basis.
V. SPECIFIC PROCEDURES SQRT procedures provide for both generic discussion meetings and plant site visits.
- 1. Generic Discussion Meeting:
To implement the generic review specified in IV.1 and IV.2.A, a generic discussion meeting will be held to discuss the following:
A.
Meeting Agenda Meeting Objectives by SQRT 11979
- B. -NSSS or A/E.personnel should be prepared to present the following information:
(1) A detailed description of current practice followed in equipment qualification, including acceptance criteria, methods, and procedures used in conducting testing and analysis. Present-and discuss the equipment qualification program on certain specified items (i.e., pumps, valves, diesel generators, motors, bistable units, relays, electrical cabinets, etc.)
(2) Information regarding administrative control of equipment qualification, especially the handling of interface problems, documentation, and internal review procedures.
(3) Identifying the scope of their suppliers. A list of equip ment should be made available if possible prior to the meeting.
C. For the cases specified in IV.2.A, methods and procedures for conducting equipment qualification review are discussed, including selection of plants for site visits and setting up a tentative schedule for such visits.
D. Discuss necessary documentation.
E. Inspect testing facilities, if any. Testing capability, format of testing reports, wave forms of shaker table motions, and monitoring and control devices are the major items for inspection..
F. SQRT concludes the meeting and specifies the follow-up items.
- 2. Plant Site Reviews:
To implement plant specific equipment qualification reviews specified in IV.2 above,.on-site inspection of equipment and supporting structures in question is required. Site visits generally follow the following procedures:
A. Pre-visit information-submission:
The applicant (plant owner) receives initial information concerning the intended visit, and should subsequently submit two summary equipment lists (one for NSSS supplied equipment and one for BOP supplied equipment). These lists should include all safety related mechanical components, instrumentation, and control equipment, including valve actuators and other appurtenances of active pumps and valves. In the lists, the following information should be specified for each item of equipment:
(1) Method of qualification used:
(a) -Analysis or test (b) If by test, describe whether it was a single or multi-frequency test and whether input was single axis or bi-axial (c) If by analysis, describe whether static or dynamic,
-6 single or multiple-axis analysis was used.
Present natural frequency of equipment.
(2) Indicate whether the equipment is required for:
(a) hot stand-by (b) cold shutdown (c) both (d) neither The scenario to be considered for this determination is:
(i SSE or OBE, with coincident (ii) loss of offsite power, and (iii) assumption of any single active failure.
(3) Location of equipment, i.e., building, elevation.
(4) Availability for inspection (Is the equipment already
-installed at the plant site?)
(5) Provide a description of how cold shutdown is reached using the equipment in item (2) above.
B. SQRT screens the above information and decides which items will be evaluated during our forthcoming site visit. The applicant
-7 will be informed of these items and will be expected to submit two weeks prior to the visit an equipment qualification suRmmary as shown on pages 10-12 for each of the selected items.
C. A brief meeting is held at the beginning of a site visit with the following agenda:
(1) SQRT explains the objectives of the site visit and procedures to conduct equipment inspection.
(2) Utility personnel or their designees present an overview of the seismic qualification program conducted.
(3) The seismic qualification of certain specified items may be discussed as necessary.
(4) SQRT specifies items that need to be inspected.
D. SQRT conducts inspection of specified items.
E. SQRT describes findings of the inspection.
F. General discussion.
G. SQRT concludes the visit and specifies needed information and the follow-up actions.
- 3. After each visit SQRT will issue a trip report, which identifies findings, conclusions and follow-up items. Status reports may be issued as necessary. The site review will include the issuance of
an Evaluation Report for the specific plant.
Generic evaluations will be referenced to the NSSS vendor or A/E.
VI.
