-(1) 2BVS-224, pp.1-28 and 1-29, prescribe certain stress limits; e.g., for (1/2)
~
SSE plus Design loads, the nesbrano stress limit is 1.Os. The Spec., p. 2-3, specifies a design pressure of 130 psig. De Sefsuic Analysis does not ap-Pear to address stresses due to the design pressure of 130 psig. Please pro-vide, in particular for the portion of the pressure boundary at the outlet which appears to be like a sitered joint, your checks made to assure that the stress limits shown on p.1-28 of 2BVS-224 are set.
(2) The hydrostatic test, and its vitness by an Authorised Nuclear Inspector, is deemed to be an important part of assuring pressure boundary adequacy. , To com-plete our audit, please provide the completed form which shows that the test has been run and witnessed.
- (3) The Seismic Report refers to 2BVS-224, Rev. 2,12/9/80. The copy of 2BVS-224 furnished us is Rev. 3,8/27/82, with Addendas 1-4, Addenda 4, dated 2/17/83 Please describe the procedure used to assure that Seismic Reports are appro-priate for current Specifications Motor Operated Butterfly Valves (4) The " Seismic Analysis" refers to " Spec. No. 2BVS-76A". We find no further ref-erence,to that specification in the Seismic Analysis; in particular; it is not included in the references. Please identify the particular 2BVS-76A revision /
addende that you think was used in the Seismic Analysis and explain why you think so.

.l' (5) We have fond no obvious timin between h Seismic Analysis and h valve identifications given in 2BVS-764. The Stone & Webster cover sheet appears to have a timin by the S&W Equip. I.D. Code; 2SWSaMOV107. This would seem to imply that Spec. pages 1-12 and 2-6 are applicable to the particular valve cov-ered by the Seismic Analysis. In this particular case, the tie-in indicated by the S&W cover sheet appears to be appropriate. However, in general, how ;
1 do you make sure that a Seismic Analysis is applicable to a specific valve (s) identified in the valve specification?
(6) The Seimic Analysis, p.11, shows a valve torque of 21068 in-lb. How does this torque correlate with the torques shown on p. 2-6 of 2BVS-76A7 (7) The Stress Analysis, p.17, appears to ignore the stem shear stress due to the specified (2BVS-76A, p.1-12) differential pressure of 153 psi. If this is true, why was it ignored?

nish the appropriate drawings that will provide assurance that the analytical change was incorporated into the valve construction.
(11) The Seismic Analysis does not cover the analysis of the bolted-flanged joint connecting the valve to the piping. This is acceptable provided the adequacy of the joint is checked as some part of the evaluation. To oceplete our audit on this aspect, please provide the docuentation (perhaps a Pipe Stress Calcu,-
lation package) which includes evaluation of the flanged joint for the valve covered by the Seismic Analysis.

but also in the piping to which the support parts are attached *.

(15) 2sys 939A, Pipe Classes This document is deemed to be significant because it appears to be the major and, in many cases, the g pathway through dich the compliance of Beaver Valley piping with the very important requirements of Code N#NC/D3640 are checked.
(a) As a coment (no response needed), the " Memo describing how anzimus D sign conditions are determined for Pipe Classes" would be clearer if the relative simple equations used to detemine P bye a quation (4) of h3641' were written out. Eq. (4) of W3641 depends upon which Code Editioq/
Addenda is being used and there is a minor ambiguity in the Code defini-tion of "da. (Are diameter tolerances to be included?)

l 5 of 7 (c)543641.2 is on straight pipe under external pressure. How is this Code requirement checked? For example, 2BVS-76&, p.1-26, indicates a posai-bility of a 45 poi pressure existing inside contaissent, which implies a Possibility of a 45 psi external pressure on piping inside cont =1=ent. ;
2BV.M39A, for Class 151, includes pipe up to 42-inch size with 3/% inch wall. The Code allowable external pressure for that pipu is about 15 psi.
We do not find any restriction or warning that this pipe may not be suit-able for use inside containment.
(d) Tab 3es for Pipe Classes 302 and 601 do not invoke the use of B16.9 for butt veld and fittings. Accordingly, fittings purchased to meet the re-quirements of these two Tables would not provide fittings in accordance with NC-3649. While most of the Pipe Class Tabl,es include a heading "Not applicable for ASME III", Pipe Class Tables 302 and 602 do not have that heading. Your explanation as to why B16.9 is not invoked in Tables 302 and 602 is requested.
(16) Conformance to ANSI B16.9, Your Piping Date Iten 7 involves a purchase order for elbows; Item 8 involves a purw chase order for a tee. Keither of these purchase orders invoke 316.9. For Item 7, the inclusion of 'I/R' appears to provide sufficient assurance that
!!O-3649 has been not. However, it is not apparent that the too in Iten 8 neotn the requirements of !!C-3649.
l The center-to-end dinension of the 10!TS no is Ei ven as 8-9/32". The centor-to end dimension of a B16.9 10NPS toe is b1/2". Accordingly, the too has non-standard dimensions. From the standpoint of meeting the pressure-design re-quirements of NO-3649, this is not necessarily a trivial deviation because it controls the space available to provide reinforcement of the opening.
SA-403 says: " Fittings different from these standards (e.g., D16.9) may be
l 6 of 7 9
furnished in accordance with 39.8 39 says that, if so furnished, they must be marked with 39. We see no evidence that 39 was invoked in the P.O. or the tee is so marked.
However, even if the tee were marked S9 in formal compliance with SA403, the While B16.9 also perw requirements of No-3649 would not necessarily be met.
mits non-standard dimensions (with the WP marking deleted), it does not waive the requirement of Par. 9, Design Proof Test. Ris is the significant differ-ence between B16.9 and SA403 (or SA234) from the standpoint of adequacy of pree.-
sure design. Note that the Code Dimensional Standard Table invokes ANSI B16.9; no,t,SA403 or SA234.
In view of the preceding, we requires (a) A list of butt welding end teos used, or to be used, in Beaver Valley Code

(19) The f-faster we note that 25 6 45, p. 12, discusses the dependones of f on am ber of se eles. Your Stress Aanlysis Data Paekage IB6-100A lists a number of system oon-ditions but we find no indication that any consideration was given to this Code requirement. For example, P. 6 of W 100A describes "a large tempern-ture sving" with no indication of how masy times this might occur. Please identify that portion of your specifications which provides the basis for the 30,!1 including the staber of times the "large temperature swing" occurs.

j "At points 41, 45, 56 and 35, (Pt. of intersection with amm11 bore piping), '
the stress intensification factor for the rssa pipe is assumed to be 1.5.
This is conservative. " ,
) On p. 36 of I99E, the SIF for point 6 is appropriately calculated by the Code equation:
SIFz09(R/T) c0.9(1.25/0.375)2/3=2.009 ,
For points 41, 45, 56 and 35, the code equation gives:
SIF = 0.9(1.6/0.300)2/3 s 2.747 Noting that the Code SIF is 1.8 times as high as your assumed 1.5, what is the basis for your 'This is conservative 87
