Dear Comissioner Ahearne:
I am pleased to transmit to you the first report of the Advisory Panel for the Decontamination of Three Mil-Island, Unit Two.
As you know, the Advisory Panel was established by the Nuclear Regulatory Commission 1980, to consult with and provide advice to the Commission on October 28, The Commission requested on clean-up act!vities on Three Mile Island.
the Advisory Panel provide advice on the Draft Programmatic Environ-that mental Impact Statement (PEIS, NUREC-0683).
In your letter of November 1980, you requested that we address specifically the question of 7,
disposition of processed water.
During a later telephone conversation, 28, 1981.
you set the deadline on the water question as of February It has held several The Advisory Panel has reviewed the Draft PEIS.
meetings and heard testimony by representatives of Metropolitan Edison of Energy, the Advisory Cc,mpany/ General Public Utilities, the Department Committee on Reactor Safety and Safeguards, and members of the public.
Sefore I detail the reco.mendatiom of the Panel concerning t.he proces-sing of the contaminated water at ~M I, I have been asked to express a That concern is the very real concern of the panel members in general. low /high level radioactive inability te dispose of the as a result of processing the contaminated water.
The Panel's deep ccacern is that TMI is being converted into a storage area for this vaste, as a result of a lack of, or the inability of, the Regulatory agen:ies to allow disposal cf the vaste promptly and efficiently.
We, the Fanel, feel that dispesal ef the waste is a package item in the

It makes little sense to precess the water is te be renoved fr:r the Containment if the rerulting radicactive vaste I cannot Euilding te :ther areas en the Is:and fer indefinite stcrage.I would caphasize in: ugh the ccntern of the Fanel on this mattcr.

Following are the recommendations of the panel concerning the contami-nated water:
RECOMMENDATION #1.
That the radioactive contaminated water located in the Reactor Building be decontaminated a.
as rapidly as possible, using the licensees proposed Sub=crged Demineralizer System (SDS) currently being constructed.
This recommendation, specific to the SDS System, is contingent upon approval of that system by the Nucicar Regulatory Commission.
RECOMMENDATION #2.
That the approximately 1.6 million gallons of decontaminated water expected as a result of TMI-2 decontamination activities, be stored initially in on-site tanks, to permit accurate assessment of its residual radioactivity concent prior to a final decision regarding ultioste disposal of the water.
S RECOMMENDATION #3.
That the appropriateness of the con-tinued on-site storage of the decontaminated water be reyfewed annually by this Advisory Panel.
RECOMMENDATION #4.,That to the extent,practicabic, Metropolitan Edison Company should minimize additional on-site water requirements, by maximizing the use of recycled decontaminated water.
. RECCMMENDATION #5. That the radioactive contaminants (excepting tritium) in the unprocessed water at TMI-2 should be reconcentrated and immobilized as expeditiously as possible, consiste'nt with Regulatory requirei..ents.
RECOMMENDATION #6.
That the' design and operation of decontamination systems for processing radioactively contaminated water shoulo minimize, as f ar as practicable, the amounts of residual radioactivity in the resulting processed water.
The Panel believes the following curie-inventories for all processed water resulting f rom cican-up activities are achievable:
