Darrell G. Eisenhut, Director Division of Licensing FROM:
Richard H. Vollmer, Director Division of Engineering
SUBJECT:
DEFINITION OF ISSUES T0 BE PROVIDED TO PG&E FOR FORTHCOMING MEETING As we discussed today, the following issues should be provided to PG&E for their consideration and discussion at a forthcoming meeting:
1.
PG&E should provide a detailed technical justification for 3

[elP i
their evaluation and shimming of closely-spaced rigid-to-rigid j
restraints and anchors. As part of this evaluation PG&E I
should erarine criteria different than those used for Diablo O[,h M44 g Canyon and justify the criteria used for Diablo Canyon.
In a J
similar manner, demonstrate the analysis for functionability f, Q (
of snubbers that were installed next to rigid supports,
/[
Demonstrate that the criteria used on Diablo Canyon will not L
g provide excessive piping loads.
h, f1 p
2.
with respect to the Independent Design verification Program, c
reevaluate the IDVP's assessment of work done by various internal and contract groups in assessment of piping and kn support loads.
In particular, focus on the rationale used by IDVP in not taking a larger sample of piping problems when IDVP uncovered deficiencies in a high proportion of the sample taken.
3.
Provide those measures that are currently in place or are to be instituted on current and future work activities performed by any and all onsite engineering groups in the following areas:
a.
Personnel indoctrination and training to assure effective implementation of all QA and technical program requirements; b.
An upgrading of site procedures and avoidance of use of unauthorized documents to perform work functions; N N' n/
