Subject:

Request for Additional Infomation - Catawba Nuclear Station in tne perfomance of the Catawba Station licensing review, the NRC staff has identified the need for additional infomation in the Mechanical Design Documentation area as stated in the Enclosure. We request that you provide the information needed no later than July 30, 1982. If you require any clarification of this matter, please contact the project manager, Kahtan Jabbour, at (301) 492-7821.

The reporting and/or recordkceping requirenents contained in this letter affect fewer than ten respondents; therefore, OMB clearance is not required under P.L.96-511.

I l ENCLOSURE 210 Mechanical Engineering Branch , 3:

210.117 In the staff's review of the design documents for the auxiliary feedwater pumps, it was determined that the design report by Mcdonald

, Engineering (Report No. ME-751) entitled, " Seismic Stress Analysis of

, Motor Driven Pumps," did not adequately address the pressure boundary checks required by the ASME B&PV Section III Code. It is requested that the applicant obtain and provide to the staff, the manufacturer's (Bingham-Willamette Co.) calculationIs for the Code-required pressure boundary checks.

Additionally,.it is requested that the applicant clarify the following questions from our review of the Mcdonald Engineering stress report:

a. What is meant in 5.8 of ME-751 by " proof tests"?

~

b. What is the basis for each of the allowables shown'in the 6

" Summary of Results" (p.3 of ME-751)?

210.118 As a result of the staff's review of Design Specification No. CNS-1205.00-5, " Nuclear Safety-Re. lated Stainless Steel Valves", we find that Attachmen't 5.8, Class 1 Valve Transients, is still incomplete. Provide the seven missing figures for our review.

Additionally, provide Attachments 5.14, 5.15 and 5.16. (As an editorial comment there are currently two 5.14's and no 5.15 attachments).

The design specification (CNS-1205.00-5) should be revised to consider the crucial aspect of design pressure and temperature and provided to the staff.

2 210.119 We have reviewed the report (NSR 71490-1, Rev. A, 11/10/76),

1:

entitled, " Design Report of 12 inch 1512 lb. Stainless Steel Cate

~~

Valve with Motor Operator". The report (p.3) lists drawing numbers used to obtain dimensions used in the analyses. Provide the drawings

, used in the report portion II, A through E. (For example, dimensions r,th, z d, and rg).

210.120 We have reviewed Specification No. CNS-1206.02-01-0001, 12/10/79, Rev. 2, " Design Specification, ASME III, Class 2 & 3 Piping", Rev. 4.

Provide a data file for a Code Class 2 or 3 piping system which uses C,NS-1206.02-01-0001 as the design specification. The piping line should have a run pipe of 12" diameter or larger and contain at least one j branch connection.

j .

! 210.121 The staff has reviewed the Class 1 stress report on RCL drain lines i (EDS Report No. 01-0093-1159).

t .

g Table 1.0-3 indicates a usage factor of 0.032 for " Joint Name" 142.

l Page E62, first line, shows "Cumul Usage" of 0.032, along with " Maximum '.

Sl a lt."

f 210,000 psi. From the Code Fig. 1-9-2, the number of allowable design cycles fof S = 23',000 is about 130. The usage factor of 0.032 a

implies that the number of anticipated cycles associated with S,= 210,000 is about 0.032X130=4 cycles. Provide the basis for assuming only 4 cycles for the fatigue analysis.

Picase furnish a detailed description of how the usage factor of 0.032 was determined.- The description should include, for each of the transients in Table 4.6-1:

(a) The pressure range (b) Moment ranges due to thermal expansion and OBE (separately) l L

3 (c) Fluid temperature changes as a func*. ion of time (d) Ranges of T, y T , and (T -

2 T) b

~

(e) Stress indices used in the evaluation. If not given in the Code, indicate their source.
