Mr. B. J. Youngblood October 5, 1983 EF2 - 65,898 Page 2 The following is submitted in response to Generic Letter 83-24 (Reference 7) dealing with TMI Action Plan I.G.1, Special Low Power Testing and Training.

Detroit Edison has confirmed an earlier statement (Reference 5) that the station blackout test would pose c risk to drywell equipment. Calculations indicate that the non-safety related equipment in the drywell would reach a limiting temperature (185 degrees F) within approximately three (3) minutes. Therefore, since the test would provide little if any meaningful data but has a high potential of damaging equipment, Detroit Edison will comply with the BWR Owners' Group recommendation to constitute compliance with Item I.G.l.

This position has been confirmed in analysis performed for the Susquehannah and LaSalle plants.

As noted on page 20 of Reference 6, Detroit Edison has supported the BWR Owners' Group position as being necessary and sufficient to meet the requirement of Item I.G.l. Detroit Edison reaffirms this position and commits to comply with the Owners' Group position detailed in Reference 6. The special tests so defined will be incorporated into our present programs for preoperational and startup testing and will be handled in the same manner as the other tests and test procedures within this programming in accordance with the requirements of Regulatory Guide 1.68.

It is the position of Detroit Edison that the above commitment supersedes previous commitments made in References 2, 3, 4, and 5. Section H.I.G.1 in appendix H of our FSAR will be revised to replace all l

previous commitments related to the Station Blackout test with a commitment to comply with the BWR Owners' Group position.

If you have any questions, please contact Mr. O. Keener Earle (313) 586-4211.

Sincerely, cc: Mr. P. Byron Mr. M. D. Lynch
