Dear Dr. Kuo:

On December 21, 1982, a meeting between NRC, PG8E, TES and BNL representatives was held at BNL.

During the meeting, BNL representatives made a number of requests for additional information to expedite the BNL verification ef forts.

These requests are summarized in the attachment.

Please formally transmit these requests to the Diablo Canyon Project Office.

sincerely b

ATTACHMENT

-Information Requests 1)

Please provide the "as built" Young's Modulus of the concrete in the-crane wall.and interior concrete..

2)

Please provide marked up annular steel " Design Change Sketches" to indicate what is new.

3)

Referring to the drawing list presented on ~pages 16-17 of NUREG/CR

-2834, please confirm that listed drawings are the latest revisions.

~

Please transmit a copy of the latest revision for those drawings found to be out dated.

4)

It is understood that the DCP is making changes to the annular steel.

Please transmit a notification and description of such changes as soon as they become available.

5)

Please provide reinforcement details for the connection between the annular slab at elevation 140' and the crane wall.

6)

.Please provide,a description of the weight distribution of the steam

(..

generators along their vertical axis.

If available, also provide stick models of the steam generators showing mass, stiffness and ge omet ry.

7)

It is anticipated that BNL may need information regarding the specific manner in which Class 1 and Class 2/3 evaluations are implemented in the ME101 and West Dyn computer codes and in.the interpretation of computer input-output li stings.

BNL will formalize these requests at a later date.

8)

Please provide the support excitation spectra for each support and each piping problem selected for BNL verification.

9)

Please provide the seismic anchor movements for each support and each piping termination point for'each piping problem selected for BNL veri fication.

10) Please provide notification of any changes that will affect the piping verification ef fort as soon as possible.
