SECTION II i
Additional Subjects Inspected, Not Identifie in Section I, Where No Deficiencies or Unresolved Items Were Found l.
General I
a.
Essentially all of the valves on this contract had already been shipped. Valves remaining at the plant included one lot of seven valves which had been rejected (for final cleaning) by the purchaser, and one lot of five completed valves which had been final inspected, except for a re-test of seat Icakage.
b.
The purpose of this audit was to observe the vendor inspection of the Crane Company's Chapman Division, conducted by MPR Associates for the Metropolitan Edison Company, i
2.
Organization The Crane Company, Chapman Division quality assurance organization pertaining to the applicant's valves was examined.

Details of Subjects Discussed in Section I*
5.
The Crane Standard Operating Instruction (SOI) for the valves on the subject order specifies ASME B&PV Code,Section VIII acceptance I
criteria as required by Code Case N-10.
The purchase order re-quirements (B31.1) are more restrictive in defining linear indi-cations.
~~
I 6.
The Crane Sol requires PT of all cast surfaces and the weld prepara-tion surfaces, but does not require PT of all machined surfaces as required by the purchase order.
~
7.
The MSS-SP-61 requires backseat hydrotest at the shell hydrotest pressure. Crane performs backseat hydrotests at the seat test pressures. The 2-1/2 inch gate valve (RO-179) Data Sheet did not record that a backsea' pressure test had been performed, although an entry space had been provided on the Data Sheet for this purpose.
8.
Some of the ca_ stings on the subject order had been stamped with sharp-edged high-stress stamping tools. USAS B31.7 requires the use of low-stress or interrupted dot stamping tools.
(')
9.
The well thickness on the nozzle portion of three valves was less than the bill of materials (USAS B16.5) required:
Valve B16.5 Recuirement As Measured R0-75X7995 1.718" 1.65" RD-76X7968 0.750' O.52" i
R0-75X7994 1.718" 1.60" 10.
The weld preps on valves RO-76 and R0-78 did not conform to the requirements of Drawing PE143701, Figure 4 (GAI approved).
11.
Examination of the data package for 2-1/2 inch check valve R0-78 MUZ863 showed the following:
i a.
Shell hydrotest tLee is three minutes.
Specification is 30
- minutes, b.
Seat hydrotest time is 1/2 minute.
Specification is three minutes.
c.
No PT on weld prep or other =achined surfaces.
