By recollection, the San Onofre procedure required traceability to NIST or "major industrial nations". We did not keep a report on file for defense. Roger Schanzenbach, CHP From: Martinson, Tim [mailto:[email protected]] Sent: Tuesday, December 5, 2017 1:00 PM To: Lamons, John <[email protected]>; [email protected] Subject: [powernet] RE: The use of equivalent Primary Calibration Standard for sources Hello John, Regarding equivalency of calibration standards; NIST, the German PTB and many other nations standards institutes are signatories to the CIPM Mutual Recognition Arrangement (CIPM MRA). This includes radiation standards. You can go to the CIPM website: https://www.bipm.org/en/cipm-mra/ to see the members and specifics. All participate in extensive intercomparison programs to verify equivalence. This was brought up years ago when I was in HP at the Kewaunee Nuclear Power Plant. The NRC accepted our use of standards produced by the German, French and Czech's. Employing them correctly has, at least to me, always seemed to be where people made their mistakes......

If so, do you have an evaluation that was performed prior to accepting said standard?
