1 1983 NOTE T0: Hans Schierling FROM:
James P. Knight, A/D CSE, DE Attached is a specific list of the information that we will need in order to conduct a meaningful audit on October 25-27, 1983, regarding the various allegations received in the course of the Diablo Canyon review. Also included under Item B on this list is a list of information to be audited in relation to open items.in SSER Nos. 18 and 19.
It is our intent that these lists be telefaxed to PG&E so that the first package of information (Item A) will be on the table ready for us to proceed at 9:00 a.m. Tuesday, October 25.
