Washington, D.C.

Dear Chairman Ahearne:

Yesterday, I received a copy of the report prepared by the Oak Ridge National Laboratories which further examined the timing schedule for the use of a Selective Absor'etien System to remove the Krypton-85 from Three '4ile Island Unit 2.

I have been informed that the Department of Energy is providing a copy of that report to you.

After reviewing this document, I believe that it reinferces my position that the time requirements proviously identified in the NRC Environmental Assessment for making this system operational at Three Mile Island were overstated.

The Oak Ridge report indicates that this process could be ready for operation at Unit 2 in 13 months.

While I am pleased that this estimate is a significant reduction from the pre-vicusly identified 18 month "best effort," I think that the Oak Ridge estimate, when reviewed in conjunction with the component availability report prepared by the Science and Technology Committee staff (which I provided to you yesterday), bears out my view that it is possible to have this system in place in about six months.

The Oak Ridge report indicates that about Si months would be needed to construct and test the Selective Absorbtion System at Oak Ridge, and then disassemble, transport, and reassemble the unit at Three Mile Island.

While it may be possible to reduce this time even

.further by doing the initial construction at Three Mile Island rather than at Oak Ridge, if we take that estimate and couple it with the procurement time estimate identified in the Science and Technology Committee staff report (a copy of which is enclosed) we again arrive at a total time requirement estimate of around six months.

I believe that the procurement estimate prepared by the committee staff is a better reflection of what is possible under an expedited procedure because that report looked at a very different way of obtaining the components than was used in the Oak Ridge procurement time estimate.

Oak Ridge assumed that all of the equipment would be purchased on the open market.

The Science and Technology Committee staff assumed that those parts which are already in the possession of the federal government would be transferred for use in this process.

Obviously, a transfer of components which the government already owns could be accomplished considerably more quickly than if everything had to be bought from vendors.

This is not to criticize the Oak Ridge approac ig g r.

Union Carbide is not in a position THIS STATioNCRY PRINTED oN PAPCR MADC WITH RECYCLCD FIDERS

Page 2 Hon. John F. Ahearne May 9, 1980 to inventory federal possessions and could not reasonably have been expected to address the possibility of transfers.

It does suggest, however, that we can still realize substantial reductions in time beyond the Oak. Ridge procurement time estimates.

Keeping this fact in mind, I believe that the Oak Ridge report further substantiates my conclusion that the original time requirements identified by the NRC staff were too long.

Six months is probably a more accurate " ball park" figure if you assume that we are expediting the installation of a Selective Absorbtion System.

I am pleased to hear that the Commission has contracted with a private firm to reevaluate the initial time estimates.

I am looking forward to continuing to work with you en this rest important issue.

Sincerely,

Subject:

TMI - Krypton Removal System

1. The Krypton removal system could be constructed in six months.

A schedule of activities is attached.

?P

2. The following conditions would be essential to meeting the 6-month schedule:

a) First, the NRC would have to concur with the project based on standard ASME codes for unfired pressure vessels.

b) There would be no time for the preparation of an Environmental Impact Statement in the usual sense; although an expedited effort could take place in parallel with design and constuc-tion af ter NRC concurrence, c) Metropolitan Edison would have to accept this alternate for Krypton removal.

d) Adequate funding would be required.

e) If Metropolitan Edison were to manage the project, procurement problems would be minimized.

If DOE managed the project,

" emergency" procurement measures would be essential to meeting schedules.

f) Interagency transfer or loan of property would have to be expedited on a priority basis.

g) The assembly work at Oak Ridge would have to be accomplished 2 shift per day basis.

The installation work at TMI on a would also have ~to be done on a 2 shift per 6ay basis.

3. One plan for accomplishing the work would be to pre assemble much of the system at Oak Ridge, on skids that could be trucked to TMI.

The molecular sieves and combination column would need to be in-stalled at TMI because of their hEi'ght.

Provision for road vibration dampening would be required.

w.

4.' Th3 projcet orgcnization should include a single project manager who has had considerable experience in managing construction pro-jects and who has effectively dealt with labor unions in such matters.

This manager should be accountable for the entire de procurement, fabrication and construction.

He should be supportee by Oak Ridge / Union Carbide process engineers and by design en-1 gineers and draftsmen.

The construction work would be principally supported by experiencG welders, pipefitters, iron workers, and electricians working on a 2 shift per~ day basis.

Independent of these persons, a separate quality assurance team should be made available to oversee the design and construction.

This team would begin work at Oak Ridge and move to TMI during installation and start up.

The third group of people would be four shifts of operators to be '

on hand during construction at Oak Ridge and to then move to TMI for operation.

Presumably they would be employees of Metropolitan Edison.

5.

available where possible.The process design would be made to accom designing an optimum system and then searching for equipme meet the design.

6. Recruitment of personnel should be from various organizations.

These might include: NRC, Metropolitan Edison, Bechtel, DOE, Union Carbide, NASA, other private firms.

persons for the task should be considered. Only the most qualified basis, this should be possible.

On a temporary loan

7. One of the first Possible sources of financing are: steps is to determine the method of fina Government.

Metropolitan Edison, Federal
