It measures 20al X dOW X 90H in. and weigns acout 3900 los.

It is located in the control room of auxiliary outloing at an elevation of 546 f t.

The field mounting consists of welding to tne floor.

The referenced qualification Seismic 02alification Test Report No. 22A4315 of July 23, documents are:

1976 (for cench board H13-P603) and Sargent and Lundy Analysis EMD-021333.

Seismic Load is considered for the qualification.

Tne cualification of tnis cenen boarc involves two separate efforts.

This GE sencn ocard (H13-P601) is quite similar to anctner GE cenen boarc (H13-P.603) installed in Fukusnima 6.

Hi3-P532 is sligntly smaller in size than H13-P601. H13-P601 was analyzed for stresses by Sargent and Luncy.

The cynamic analysis model consistec of a 30 beam finite elements and response scectrum input. There were 25 moces in tne ringe of 1 to 35 Hz.

5AP 17 computer program was used. Mooal dynamic responses were aosolutely summed for closely spacea modes anc SRSS for overall response. A two percent camping was used in tne analysis.

Tne analysis discovered some overstressed points and recommenced scme field modifications.

11. POWER RANGE NEUTRON MONITOR CABINET (H13-P608)

The neutron monitor caoinet is suppliec by General Electric and has Model No. 328X105TU.

It is mountec to a floor.emoeddea plate witn welds of 2 in, length at 12 in. intervals.

It is qualified oy tne GE cocuments "Q;alification Test Report for ?ower Range Monitoring Instrumentation,"

235A1893, Septemoer 25, 1972, and " Power Range Monitcrirs Caoinet, Seismic Qualification Test Report," August 25, 1975.

The cabinet is suoject' to seismic ' loading.

This item was qualified on the basis of tests performed on a 5-cay hanforc 2 panel.

It is identical to tne Zinner 508 pant!.

During tests, the caoinet was secured to the ficer of tne taole wi:n 22 colts and clamps, wnicn makes tne Zi=ner welced installation conservative.

Accel eremeters sere attacned and transmissioilities recorcec. The majcr resonances in eacn cirection are:

The panel was single frequency sine dwell testec at 0.7 g norizontal-and 0.4 g vertical at eacn integer frequency in :ne 1 to 33 Hz l

range.

The Zimmer required IPA's are 0.4 g horizontal anc 0.45 g vertic al.

Eauipment was monitorec for false trips and improper operation anc no proolems were cetected. When tne tes: g levels were increasec to 1.3 g nori: ental anc 1.2 g vertical, several f ailures.occurrec. Witn mccificarians mace to tne macule restrain sys em, power supply plugs, carc succor cage, anc coor latenes tne cabinet was acle to meet :nese g levels.

Out of these ten were of OBE (5 in, eacn orientation) and two of SSE (one in eacn orientation) lev,els.

The input ZPA levels were S/S = 2.48 g; F/5 = 3.95 g and V = 5.6 g.

The multiaxis, multifrequency witn random input tests are tne appropriate tests.

The input IPA's are well aoove the requireo ZPA's of S/S = 0.6 g; F/B = 0.6 g and 1.02 9 Tnere were sufficient numoer of 08E 3

In general, tne TRS do'es not envelope tne RRS in tne range celow t Hz.

This is not significant since the e.quipment frequency is reasonaoly removed from it.

Tne acclerometer locations were sati sf actory.

LPPOSEO ELADE SALANCING DAiPER The Opposed Blade Balancing Oamper is supplied by Tuttle and Sailey and nas Mocel No. A718.

It is qualified oy the cocument "Requalification of HVAC Opposec-Blade 'lolume Control Salancing Dampers," Sargent anc Lundy, Feoruary 17, 1981.

The camper is suoject to seismic and hydrodynamic loads.

Qualification of tr.is damper was performed by analysis.

In the analysis, tne damper blade was assumed to se a unifonnly loadeo ceam simply supported at the ends.

The maximum olace length for all sucn campers was used and tne damper frene was assumed rigic.

The lowest natural frequency calculated for tne pin-pin ceam was 23.9 cas.

The Xapur-Sheo metnod was used to cetermine tne response g level for tne olace witn tne natural ' frequencies of tne damper and supporting hanger known.

The analysis was cone using tne worst response spectra at tne nanger locations for all sucn campers.

The maximum clace response was calculatec for each nanger-camper comoination in tne plant.

The worst case camper resconse was 1.35 g EW,1.45 g NS, and 3.07 g V.

A value of 6 g in eacn cirection was usec in tne analysis.

i The cirectional accelerations were cecoinec using SRSS anc :ne pressure f orce was accec in.

The resulting clace cencing stress was calculatec to ce 21030 psi, wnica is less tnan tne allowaole stress of 32C00 psi.

The clace ceflection was cetarminec to ce 0.5 in., wnica is accaotaole.

Stress on tne bearings was only 7S6 psi anc snear stress in tne slace snaf t was 900 psi.

No. LCT 20/ 51.

It is qualifiec ty the document " Seismic Calculations Safety and Relief Valves," J. E. Lonergan Co., Octocer 21,1976, and by suo:equent calculations performed by Sargent and Lundy.

Tne relief valve is suoject to seismic and hydrodynamic loads.

This item is qualified oy analysis.

In the analysis performec by tne J. E. Lonergan Co., tne natural frequencies for lateral bencing and of tne valve's spring system are approximatec.

Seismic accelerations of 3.5 g in eacn direction are apoliec at tne C. G. of the valve.

The loads at the no::les are tnen calculated as reactions to tnese accelerations. This metnoc coes not appropriately account for motion of tne piping in the detennination of tne noz:le loacs. The Lonergan analysis finally detenninec tnat tne valve section moduli and metal area at the inlet anc outlet are significantly nigner tnan tnat of the attacnec piping.

Sargent anc Lunay later aerformed an analysis on tne valve.

The natural frequency for cencing motion was recalculated, using less conservative assumptions, 'to ce 58 Hz.

This suggests tnat tne valve bocy anc nousing arounc tne soring can ce treatec as rigic.

Since tne spring anc surrouncing nousing are of lignt weignt relative to tne valve cody anc are stout structure, tney were not analy:ec.

The weaker inlet and outlet t

fi anges were analy:ec for no::le loacs from tne Sargent and Luncy piping analysis.

Tne accliec ner:le loacs are as follows:

M (f :-lo)

Tne g levels ~of tne valve as 'caterminec oy tne pipirg analysis are 5.5 g, 2.1 g anc 4.4 g in tne enree cocrc. nata cirections.

The duration of eacn cwell test was 60 seconds.

The input excitation' was 4.5 g in tne norizontal direction and 3.0 g in the vertical direction.

Operacility of ne valve was cemonstrated before, during, and af ter the sine cwell tests.

The requirec I?A levels are N-S 0.36 g, E-W 0.42 g, vertical 0.75 9 The test values greatly exceec :ne required values.

Basec on tne fiele inspection anc a review of its q' alification u

recort, tne Attcmatic Solenoid valve is acecuately quclified for seismic loacing.

tne new mounting must ce rigia enougn sucn tnat the lowest natural frequency oe above 50 Ht.

Otnerwise, tne current static analysts must ce scaled up to account for dynamic suplif,ication.,

o Cn the inlet sice of tne fan is a motor operated isolation damper.

Support of this equipment for seismic appears to be questiona' ale. Seismic qualification of this piece of equipment is requested.

Based on the field inspection and 4 review of qualification reports, tne cooling f an is qualifiec for seismic loaoing pending satisfactory resolution of tne acove concerns.
