Mr. Cordell Reed Vice President Post Office Box 767 Chicago, IL 60690 Gentlemen:
This will confirm the telephone conversation of July 24, 1980, between Mr. R. Janecek and Mr. L. Spessard of my staff, that a meeting vill be held between the NRC, Commonwealth Edison Company representatives, and other operating BWR licensees at the Region III office, Glen Ellyn, Illinois on July 30 and 31, 1980.
The objective of the meeting will be to obtain an in-depth understanding of the as-built scram discharge volume (SDV) and its piping including the vent and drain valve arrangements and also including the instru-ment volume (s) in order to be in a position to review licensee recom-mendations for changes to the scram system to improve its operability and reliability.
'Ihis will be a working level meeting whose primary purpose will be to gather knowledge and materials regarding the present as-installed con-figuration of the SDV system at each plant. No broad policy decisions will be reached, and no decisions will be made at the meeting regarding acceptability of any licensees' SDV system or of proposed changes to that system.
Your attention is directed to the enclosure to this correspondence which provides a schedule for each licensee's presentation.
To obtain the desired in-depth understanding, we will want to meet separately with each operating BWR licensee to discuss the as-built valve arrangement, scram discharge volume, piping, and instrument volume (including pneumatic, hydraulic and electrical subsystems). Each session is scheduled for approximately 1 hours1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />.

Cmamonwealth Edison Company.
In order for the objective to be attainable in the time allotted, each licensee must be prepared to discuss in detail the as-built conditions in the system. Knowledgeable engineering and design licensee personnel should be available. tipecifically each licensee should bring:
1.
Marked up drawings showing as-built conditions which have been verified by a walk-thru of the system (including pneumatic, hydraulic and electrical drawings).
2.
A system description including logic diagrams as necessary to show the operation of the system.
3.
Preliminary recommendations for proposed changes to the syster.
4.
Engineering bases for the changes.
3.
Interface requirements imposed on the AE for the system designs.
6.
Interfaces with other systems.
A copy of all information (including marked up drawings) presented by the licensee should be given to the staff prior to the close of the meeting.
We realize IEB 80-17 asked for this information formally documented, by August 7.
That requirement still holds; however, the licensees should present as complete a story as possible in an informal manner on their respective meeting dates.
NRR representatives at each meeting will be V. Panciera, M. Mendonca, D. Thatcher and J. Hannon. The IE Headquarters representative will be W. Mills. Regional representatives will also be present.
Representatives of the LaSalle County Station staff are invited to attend this meeting for information purposes, and will not be required to make a presentation.
j Please refer any questions you may have to Mr. F. Reimann of my staff.
