Dear Mr. Moseley:
3 Enclosed c.re two (2) copies each of pages 4, 4a, and Exhibit I which we -
submit as Addendum 1 to our Valve Wall Thickness Verification Program, j forwarded to you by our letter of December 7,1973. It is necessary to

indicated on the contour dravings. All the valves'were evaluated in accordance with the Codes and the required tm .
listed on the large valves list (Exhibit I). The results l I
of the measurements are shown on the ND Inspt tion Reports (Exhibit IV).
! l valves DH-14 A, B, and CF-1A, B have 12" bodies with reducers j
i welded on eithr* end to suit 14" diameter pipe. The connections for all Nucicar Class I valves and reducers wer. anal.=ed and the analysis shows that there connections rect theErequire- !
j monts of ANSI B31-7 Code.
J Valve body c n:.sur at weld ends is in accordance with ANSI B 16.5. The only thic, knees restriction relate.. to the 1-1/2 t (t n nominalpipewa'llthicknes7) distance used in describing the weld en'd geometry is that the wall thickncss of the valve should not be'less than 1.15 t at this point. ,
This is per letters from ANSI Standards Committee B16 to Velan Engineering ;
Ltd. dated June 30, 1971 and February 3, 1972. (See Exhibit VIII). The measured t'm (valve body wall at a distance of.
1-1/2 t from end of the valve) was therefore compared to,a ,
i
- value equal to 1.15 -(where t = nom. wall of connecting pipe) . , ,

,h The piping upstream of valves CV-2415 and CV-2419 has been J, designed at 700 psig and-300*F, whereas the downstrear side is' designed'to 2500 psig and 300*F. We have s'hown both I these conditions'and the required t ,on Exhibit I. ~,
