Dear Mr. Arnold:

WTravers A ,

(*

JFouchard /16 By letter (LL2-81-007) dated March 11, 1981, Metropolitan Edison Company forwarded the revised Technical Evaluation Report on the Submerged Demineralizer System for NRC review and approval to operate the system as an effective means of decontaminating the containment sump water and reactor coolant. That report left unanswered many issues basic to our eview of your proposal. In order

.to expedite the NRC review of your propo ul, the Three Mile Island Program Office staff promptly reviewed your submittel and provided a list of topics for discussion with Met-Ed regarding the SDS and its use. NRC subsequently arranged a meeting for a face-to-face discussion of the health and safety related SDS issues, in lieu of the time consuming process of sending you a formal list of questions which would require a formal response.

As you know, the SDS review meeting was held over a two day period on March 31 and April 1,1981. The outcome of that meeting was a mutually agreed upon list of commitments for information required from the licensee to enable the staff to complete its safety review and take appropriate action on your proposal (Enclosure 1). NRC staff indicated at this meeting that this informa- .

tion was both necessary and sufficient for us to complete our review. By memorandum (LM2-81-0072) dated April 3 Met-Ed provided a firm schedule (Enclosure 2)

, for meeting each commitment. However by memorandum (LM2-81-0064 dated April 21, shortly after many of the items were due, Met-Ed forwarded a revised schedule (Enclosure 3) for submittal of the committed information, slipping the dates for 8 of the 23 items. Further, by memorandum (LM2-81-0091) dated April 30, 1981, Met-Ed provided a status (Enclosure 4) of the list of 23 commitments and again indicated additional slippage for your submittal from the dates provided in the April 21 memorandum.

As of May 6,1981, only 10 of the 23 committed items (Items 3, 7, 11, 12, 13, 15,16,17, 21 and 23) have been submitted in final form for review and there j

Mr. R. C. Arnold .is little ~1ikelihood that even the latest schedule. (see Enclosure 4) will be met for all items. I am.particularly disappointed that the basic processing strategy originally due on April 24. . has not. .at this late date, been formally transmitted to us. in spite of the fundamental nature of this information.

I am very concerned that, despite our best efforts to expedite the safety review i of the SDS, Met-Ed is not supporting this review with high priority, as esidenced ,

by continual slippages in transmitting information as agreed. Obviously, NRC approval will not be forthcoming until we have all required information from you, and.we can be assured of the safety of this system. You should note in this regard ,

that, in the NRC Statement of Policy of April 28, 1981 on the Final Programmatic Environmental Impact Statement (PEIS) on the cleanup at Three Mile Island, issued March 9,1981, the Comission stated that Med-Ed "...should accelerate the pace of the cleanup to complete. expeditiously all decontamination activities consistent with ensuring protection of public health and safety and the environment."

Consistent with that policy the NRC's Three Mile Island Program Office has been staffed to act expeditiously on your proposals. Compliance with this Comission request'will not be possible unless Met-Ed places the highest priority on supporting the staff safety review of the SDS.

The NRC staff has comitted to finalizing its safety evaluation report on the SDS and taking action on your proposal promptly following receipt from you of all the required information, in complete and final form. Met-Ed should support this effort at its highest priority. .I am convinced that expeditious cleanup is -in the best interests of the public. Your company, in my view, is now on the critical path. for cleanup of the containment building water.

~

I look forward to hearing from you.

Sincerely, Harold R. Denton, Director Office of Nuclear Reactor Regulation
