Dear Sir:

Three Mile Island Nuclear Station, Unit 1 (TMI-1)

Operating License No. DPR-50 Docket No. 50-289 Inspection Report 84-03 (Post Accident Sampling and Monitoring)

Our letter of March 8,1984 provided the list of actions GPUN is pursuing in regard to post accident sampling along with commitment dates targeted for completion of eacn item. Responses to certain of those items were shown to require additional sutnittals.

This letter transmits GPUN's response to several outstanding items and indicates those items which have been completed since our last submittal of May ll, 1984.

Attactraent 1 is an update to our list of outstanding items. Attachment 2 (GPUN Response) and Attachment 3 (TDR-529) provide responses to several of these items as indicated in Attachment 1.

~

Those items for which responses have been provided are not included in this sutnittal.

Sincerely,

. D. ukill Director, TMI-l attachments cc: R. Conte .. ; ! * .

OUTSTANDING ITEMS

  • 4 GPUN ACTION GPUN RESPONSE NO.

5.a.3 Boron would be analyzed in the post accident condition using the manitol method (procedure N1904 - Baron by Titration) for concentrations between 500 to 6000 ppm boron using a 1:100 dilution.

If the boron concentration is less than 500 ppm, procedure N1904.1 (Boron by Fluoroborate Specific Ion Electrode) will be used as a backup.

5.c.2 GPUN will be incorporating the use of stripped gas activity into the

. procedure for estimating core damage following an accident. This procedure is required to be upgraded by August 31, 1984 in accordance with the NRC Safety Evaluation Report for NUREG-0737, action item II.B.3, dated March 22, 1984. Procedures for analysis of stripped gas activity will be completed by August 31, 1984.
