Dear Mr. Schwencer:
The purpose of this letter is to provide an updated response to our letter in Reference (a).
In our meeting in your of fices on November 20, 1981, members o f y our staf f requested Commonwealth Edison provide an updated response addressing the
~
concerns in Reference (b).
Accordingly, the following clarifi-cations and updated status are provided:
1.
The Radwaste Ventilation Preoperational Test (P'-VW-101) has been completed.
Commonwealth Edison no longer requires deferral of this test.
This item should be deleted from our Attachment A to Reference (a).
However in response to your concern, it was not intended that contaminated material would be stored in the area until the test was completed.
2.
The column titled " Proposed Completion" on the Attachment to Reference (a) should be amended to read " Required Completion".
The intent was to require completion prior to entry into the condition listed.

The discussion of the primary containment leak rate test identified no specific concern.
It is our understanding that this item does not require Cnmmonwealth Edison action.
Furthermore, we believe all open primary containment leak test issues were resolved with the submittal of Reference (c) which addressed the increase in primary containment accident pressure (Pa) and the high pressure bypass leakage test.
The only possible exception to this would be two proposed changes to containment boundry as documented in Amendment 59 to the LaSalle County Station FSAR.
These issues are being discussed with Mr.
A.
Bournia and Mr. F.
Eltawila and should not require any 10 CFR 50 Appendix J exemptions.
4.
While we understand the concern related to plant staffing, we do not share this concern.
As stated in Reference (a),
it is expected that the majority of these tests will be completed prior to fuel load.
Deferral is necessary to allow additional time for thorough evaluation and review of test results.
Since staffing on LaSalle County Station for two unit operation is essentially complete, additional operations and test personnel are available on site to augment shif t personnel as need arises.
Su f ficient options, such as postponement o f Unit 2 preoperational testing or Unit I startup activities, are available to assure that these tests are accomplished in an orderly manner.
It in judged that the above information provides the necessary clarification and update information to allow your staf f to complete their review.
If there are any questions on this matter, please contact this office.
Very truly yours, b
