April 13, 1988 Ms. Frances Skolnick 2079 New Danville Pike Lancaster, Pennsylvania 17603 In the Matter of GPU Nuclear Corporation (Three Mile Island Nuclear Station, Unit 2)
Docket No. 50-320-OLA (Disposal of Accident-Generated Water)
Dear Ms. Skolnick:
In its Memorandum and Order (Granting Joint Intervenors' Mo-tion to compel), April 6, 1988, the Atomic Safety and Licensing Board ordered Licensee to "produce for the Joint Intervenors' inspection and copying the pertinent portions of any contract entered into with a disposal systems vendor which details the technical specifications for the disposal of the accident-generr.ted water."
I remain uncertain that I am adequately communicating Licensee's position on your document request.
In its Memorandum 4-and Order, the Board describes our position (reflected in

Ms. Frances Skolnick April 13, 1988 l
Page 2 Licensee's Answer to Intervenors' Motion to Compel Discovery, April 1, 1988) as hinging upon the circumstance that technical specifications for accident-generated water disposal have not yet been approved by NRC and included in the TMI-2 operating license.
The Board stated We do not understand the Licenses to argue that there are no extant technical specifica-r tions which, even if they are not deemed to l
be included in and thus currently do not form a part of the operating license, address the proposed method for the disposal of the accident-generated water.
Memorandum and Order at 3.
To the contrary, Licensee does not l
3 have draft or proposed technical specificatioris which, if ap-i i
proved, will become a part of the TMI-2 license.
As stated in answer to your motion to compel, we have a procurement specifica-tion which was issued to potential bidders for the disposal sys-tem contract.
So that there is no further misunderstanding on this score, t
I am enclosing for the entire Service List a copy of the perti-nent contract provisions which incorporate the procurement tech-l nical specifications, and the procurement document itself.
This complies with the Board's Order.
To repeat, these are commercial contract documents prepared for private parties.
They do not represent regulatory requirements, draft proposed technical spec-(
ifications, or eventual license conditions.
They have nothing whatsoever to do with license technical specifications, now or in the future.
Sincerely, h 4.

4.2 SOLIDIFICATION / PACKAGING Based on the evaporation of an anticipated 2.1 million 4.2.1 U
gallons of water included in the scope of this technical bid specification, is the stabilization of an estimated 150-200 tons of waste chemicals. These chemicals are currently in solution in various tanks, sumps and other isolated areas throughout the THI-2 Reactor, Fuel The Handling and Auxiliary Buildings (See Article 7).
chemicals will be collected as evaporator bottoms and 16308 5 l l
t
c transferred to a collection point. Evaporator bottoms will be concentrated to the maximum extent possible to provide a maximum volume reduction factor.
4.2.1.1 Immobilization or packaging of the evaporator bottoms will be accomplished using contractor services. This If process may or may not use an immobilization binder.
a binder is required, it is not necessary for the binder to meet the stability requirements of the NRC Branch Technical Position on Waste Form since the binder is merely to immobilize the free-standing liquids and create a free-standing monolith. The solidification binder, however, will have to be one that is approved for use per the burial ground license. It will be noted here that the bituminization processes, included with some transportable evaporator systems, is not acceptable for immobilization of the evaporator bottoms because of regulatory uncertainties regarding the ust.of asphalt as a solldification binder.
4.2.2 Upon award of contract the contractor will provide to 1
GPUNC the following information:
4.2.2.1 Written procedures covering their solidification and operation program e

4.2.3 The evaporator bottoms may be ready for solidification as early as July 1987, although the exact time period cannot, as yet, be determined. GPUNC will provide 30 days notice as a minimum prior to the start of,
solidification. Contractor will supply the following:
4.2.3.1 Containers for transfer of the waste to be solidified or packaged, in the quantitles specified by the contra'ctor and agreed to by GPUNC. At GPUNC's option, all evaporator bottoms may be transferred in batches to containers and solidification may be accomplished as each container is filled.
4.2.3.2 Mobile equipment required to solidify or package the waste.

ARTICLE 7 WATER CHEMISTRY AND VOLUMES 7.1 The plant currently has approximately 400,000 gallons of processed water ready for disposal. However, it is expected that the evaporator will process an approximate total of 2,100,000 gallons of water over a period of approx. 2 years. Much of this water will be affluent w;*+- from the plants ton exchange water processing systems. (This water is known as "Processed Water").
Estimates of water volumes by source locations, radionuclide 7.2 analyses and chemical concentrations of this processed water are provided as Tables to this Article. This data must be recognized as typical information only and is subject to change depending on plant conditions. However, the estimated 150-200 tons of sediments resulting as a product of the evaporation process, noted in Section 4.2, is accurate within the scope of this specification.
The use of these Tables is quallfled as follows:
The radionuclide analyses presented in Tables 7-1 and 7-2 7.2.1 are the actual scurce term calculations performed on each g'.ven sample during the dates noted for each of the Measured concentration values for all source locations.
radionuclides with positive (i.e., greater than LLD) values are presented in Table 7-1, while Table 7-2 presents the total activity present in each source volume. The data in these two tables represents the actual liquid source terms present at THI-2 in March 1986.
1630B SE 42 -
7.2.2 The radionuclide analyses presented in Tables 7-3 and 7-4 are the projected source terms as estimated after approximately 407. of the source water is processed by plant systems prior to evaporation. The water sources requiring processing prior to evaporation are identified with an asterisk in Table 7-3.
Tables 7-3 and 7-4 present the radionuclide concentrations and total activity, respectively, projected to exist on 10/01/86 after processing approximately 407. of the processed water.
7.2.3 The water chemistry data presented in Table 7-5 is from the actual chemistry analyses performed on each given sample on the data noted for each source location.

7.6 Reprocessina Considerations Prior to evaporation it is likely that a considerable percentage of the processed water at THI-2 will require further processing by plant systems to alnimize radioactive contaminants. The major purpose for this processing (reprocessing for some of the water) is to further reduce the radionuclide levels, thereby alnimizing the total release of activity to the environment. Of particular concern is the need to reduce the total quantity of $r-90 present in processed water.
7.6.1 The volume of water requiring processing prior to ultimate disposition is dependent upon the final method selected by GPUN for disposal of processed water.
Because of the concentrating effects of the evaporation process, it is estimated that 40% of the total water volume will require plant radwaste processing to reduce the activity levels influent to the evaporator.
Additional water processing will be performed as needed.

l e o 7.7 Chemical Concentrations 7.7.1 For each of the sources of processed water, chemical analyses were performed to characterize the non-radioactive nature of the water. Of particular interest is the boron concentration in each source since boron will directly influence any concentrates from evaporation requiring solidification, or the necessity to add stabilizing agents to ensure proper solidification.
The results of the characterization are presented in 7.7.2 Table 7-5.
It has been assumed that the chemical nature of sources recutrino processino before evaporation will not chance durino processino, and that additional water added to the inventory will not contain appreciable, quantities of boron. Several tanks reflect assumed chemistry parameters, which are bated on the best current information available.
From Table 7-5, it can be seen that most of the processed i
7.7.3 f
water has a near-neutral pH, with varying levels of I
1 I
conductivity and sootum. Boron ranges from less than 100 ppm for contaminated drains and new water, to over 5,000 ppm for RCS and BHST water. The average concentration is approximately 3,050 ppm, and is equivalent to 1
approximately 150 tons of boric acid which will be the primary constituents of the concentrates to be solidified or packaged for disposal.
