SUBJECT:
TRIP REPORT FOR SEISMIC CRITERIA IMPLEMENTATION REVIEW MEETING WITH CINCINNATI GAS AND ELECTRIC COMPANY (CG&E) j ON WM. H. ZIMiER NUCLEAR PW ER STATION The Seismic Qualification Review Team (SQRT), consisting of Engineers from the Equipment Qualification Branch (EQB) and the Idaho National Engineering Laboratory (INEL, EG&G), conducted a site visit to Wm. H. Zimer Nuclear Power Station at Moscow, Ohio, on June 2 to 5, 1981. The purpose of the visit is two-folded: (1) to perfom a plant site review of the seismic and dynamic qualification methods, procedures, and results for selected supporting safety-related mechanical and electrical equipment and their,ipment in structures, (2) to observe the field installation of the equ l
order to verify and validate equipment modeling employed in the qualifi-cation program.
The background, review procedures, findings and the required follow-up l,
actions are sumarized below. A list of attendees at the conference is contained in Attachment I, and a list of the equipment selected ft c l;
audit is shown in Attachment II.
===1.
Background===
l The applicant has described the equipment qualification program in Sections 3.9 and 3.10 of the Final Safety Analysis Report, consisting of dynamic testing and analysis, used to confim the ability of seismic Category I mechanical and electrical (includes instrumentation, control l
l!
and electrical) equipment and their supports, to function properly during lj and after the safa shutdown earthquake (SSE) specified for the plant. The applicant has also described the program for the combined seismic and hydrodynamic vibratory loads associated with the MARK II contain.: ant suppression pool.

Electronics Engineers Standard, 344-1975, "Recomunended Practices for j
4 Seismic Qualification of Class IE Equipment for Nuclear Power Generating Stations," and Regulatory Guides 1.92, " Combining Modal Responses and Spatial Components in Seismic Response Analysis," and 1.100, " Seismic Qualification of Electrical Equipment for Nuclear Power Plants," or where equipment is affected by and was not qualified for the suppression pool hydrodynamic loads, the applicant has undertaken a re-evaluation and requalification program.
The plant site review was performed to determine the extent to which the qualification of equipment, as installed in Zimmer, meets the current licensing criteria as described in the Standard Review Plan (SRP) Sections 3.9.2 and 3.10.
i, 2.
Review Procedures Prior to the site visit, the SQRT reviewed the equipment seismic qualifi-I, cation infonnation contained in the pertinent FSAR sections and the reports referenced therein. A representative sample of Seismic Category I mechanical and electrical equipment, including both NSSS and BOP scopes as :hown in Attachment II, were selected for the plant site review. The review consisted of field observations of the actual equip;ent configuration and its installation, followed by the review of the correspond'ng test and/or analysis documents.
Brief technical discussions were held during the review sessions to provide SQRT's feedback to the applicant on the equipment qualification. An exit conference was held to summarize and conclude the plant site visit.
3.
Findings The results of field observations and the review of the qualification reports and pertinent documents for equipment as listed in Attachment II are sumarized in Attachraent III for each piece of equipment evaluated.
The plant site review identified the need to provide additional information on certain generic issues as well as to clarify the details of the qualifi-cation for some specific pieces of equipment as described in Attachment III.
The applicant has committed to submit additional infomation and clarification for a follow-up review. Subsequently, on 7/21/81 the applicant sent to NRC a post-audit submittal. The follow-up actions are described in Section 4 1
4.

No. 43445-2, January 12, 1977. The valve is suoject to seismic ana nyorodynamic loads.
The valve was qualified oy botn test ano analysis. During tests, it was attacned to a rigid test fixture. It was a single axis sine sweep test to identify resonancas. Natural frequency of 21 H in tne lataral direction was identified. It was, then, subjected to ciaxial ranoom motion consisting of frequencies from 1 to 40 Hz. During tne random motion tests, the inlet and outlet flanges wert iv.ced to 800,000 anc 600,000 in-lo, resoectively. Functionality and structural intagrity were verifiec and no leakage was catected. The TRS envelopes the Wyle Laos' generic RRS, wnten is not actually Iimmer loading situation, but conservative.
Tne valve and actuator were incluced in GE's analysis of the main staam and discharge piping. The analysis was performeo using a finite element responsa spectrum method to determine stresses in ene piping anc comoonents. The SAP and ANSI 7 compu.ar programs were usec in tne analysis. The flange moments were calculatec anc found to oe less enan AST Section III Coce allowanies. As part of cne analysis, tne maximum valve response accelerations were cetannined to oe 4.33 g lateral and 2.22 g vertical, wnicn lie witnin tne TRS of Wyie's tasts for all frequencies acove 4 Hz. Tne res~onanca search cia net extana oeyonc 40 riz, out tne TRS does envelope the RRS in Inat region.

The Motor This unit (Equipment No. C41~-Q01A/13, Model No. 5K324AN2960) is suppliec by General Electric Company. 'Tnis is "also mounteo on 1/4 in, tnicx skia witn 4-1/2 in diameter molts anc tne sxid is attacned to pedestal witn 7-3/4 in. diameter bolts. Tne referencea qualification report is: " Approved Engineering Test Laos (54'D-6958) aatec 1-28-77".
The loacs consiaered are seismic and hydrodynamic.
I The motor has seen qualified througn test. Tne test mounting.is i
similar to tne field mounting. The test is a of.4xial, single frequency si1e dwell at 33 Hz. The input g-level for tne test is 2.0 g in eacn of tne norizontal direction in conjunction witn a 2.0 g in tne vertical d irection. These tests are performed during operating anc non-operating i
f mode witn no functional impainnent curing and after tne test. One OBE anc four SSE level tests are performec. Since the resonance saaren cetween
- 10 to 30 HI did not indicate any resonant frequency in 1is range tnis type of test is considered acequate. Tne required input g-level (ZP,4, since rigid) is equal to/or oelow 0.38 g in eacn or tne norizontal direction ano 0.95 g in tne vertical direction. The camoing values used are one and two percent #ar OBE and SSE respectively.
Field inspection in this case indicatec a difference netween ene fielo motor (iK324AKZl20) ana qualification report (5X324AN2960) mocal nos. A response as to their similarity or otnerwise is needed.
Based on observed field installations ano our review of tne analysis ano/or test documentation this unit consisting of tne pump anc motor is adequately qualified pencing tne resolution of the relief valve line for une cumo and model numoer ciscrepancy for tne motor.

4l QJalification of this item was perfomac by analysis. In tneir i
analysis, Van klik and Associates considered only seismic forces for dynamic loacs and tne pump was detemined to oe adequate. Witn tne l
introduction of tne T-quencner loacs, the nozzle loacs exceec tne j
manufacturer's current allowaole values. To assess wnetner tne new nozzle loaas can safely be nitastood, Singnam Willamette will re-analyze tne valve o tnese loaas and to the appropriate response spectra. Sargent anc Luncy cannot perform tnis analysis oecause the manufacturer will not release necessary infonnation.
The new analysis is to use finite elements and the response spectrum me tnoa. Stresses in all pump components are to oe calculatec witn tne current seismic and nydrodynamic loacs anc tne ccrresponding nozzle loads applied.
In order to complete our review of tnis item, we require tnat tne applicant furnish ene completed seismic qualification report wnen availaole.

I Tnis item is qualified oy analysis. In tne analysis perfomea ey tne J. E. Lenergan Co., tne natural frequencies for lataral bencing and of tne valve's spring system are approximated. Seismic accelerations of 3.5 g in eacn direction are applied at the C. G. of tne valve. Tne loads at tne nozzlek are tnen calculated as reactions to tnese accelerations. This
>l metnoc coes not ap;ropriately account for motion of tne piping in the cetamination of the nozzle loads. The Lonergan analysis finally determined that tne valve section moduli and metal area at the inlet anc outlet are significantly higner tnan tnat of the attacnea piping.
Sargent ano Lunay later performed an analysis on ene valve. Tne natural frequency for bending motion was recalculated, using less conservative assumptions, to be 88 Hz.

In the field mounting, the system of piping on wnicn tne valve was mounted 'was rather flexible ano appeared to os neeatng suppor":s. On inquiry, tne applicant stated that there we e supports to tne pioing system. Tney nad temporarily caen removed for tne punose of weeping insulation around the pipes. The supports would oe put bacx in.
The test is satisfactory oecause tne valve itself was relatively 1
stiff. However, tne g-levels (requirement level) from tne piping analysis is yet to be verifiec.
