-pG rn e J. P. O'Reilly, Chief, Reactor Inspection and Enforcement Branch Division of Compliance VENDOR INSPECTION REPORT - CRANE COMPANY, CHICAGO, ILLIN0IS The enclosed report of an inspection of the Crane Cotepany in Chicago, Illinois on October 14-15, 1969, is forwarded for information. Our purpose for conducting the inspection was to examine the vendor's capa-bilities for manufacturing nuclear quality valves. The inspection was arranged through the Duke Power Company whose purcht se of valves for the Oconee reactors was considered representative of current valve procure-
}
ment and manufacturing practices.
Our inspector selected for audit 18 Class I swing check valves which will be used in the core flooding systems.
It was determined that these valves were purchased to the new USAS B31.7 and the ASME Pump and Valve (draft July 1968) Code requirements. With respect to these requirements our inspectors found the following three items of nonconformance:
a.
Weld repair procedures and welders were qualified to NavShips 250-1500-1 instead of to the ASME Section IX code as required by paragraph 1-727.5.1 of USAS B31.7 and paragraph 512.5.1 of the Pump and Valve Code.
b.
Dye penetrant tests of all machined surfaces of cast pressure components could not be verified as required by paragraph 314.5 of the ASME Pump and Valve Code.
c.
Nondestructive testing personnel were not qualified ~ to SNT-TC-IA
~
as required by Appendix B, paragraph B-5-120 of USXS B31.7 and.
the same paragraph reference in the ASME Pump and Valve Code.
In considering the specific circumstances of this[ sihial tion, we believe that the valves supplied for the Oconee reactors are suitable for service.
We base that conclusion on the fact that the Duke Pcwer Company elected to impose higher than required standards (USAS b31.7 and ASME Pump and Valve Code) upon the supplier and that the NavShip standards to which the Crano personnel and procedures 'are qualified, are probably equivalent

c,.
J. P. O'Reilly DEC 11 N to the ASME Section IX and Siff-TC-IA rules.
However, because the non-qualification of welders and welding procedures is also in nonconfora-ance with current ASME Codes (ASA B31.1.0), we plan to notify the I f r.casee of these cons tructic.n deficiencies. A cccoadacy cbjective is to inform the Crane Company indirectly, through the licensee, that an vpdating of their manufacturing procedores to ASME Code rules is re-quired if they intend to continue to supply nuclear couponents to licensed facilities.
