CHAPTER 7 - DECOMMISSIONING PLAN 7.1 General Provision for decommissioning will be made should UNC decide to terminate this license. The facilities and site shall be decontaminated so that release for unrestricted use may be made in compliance with Tabre 7.1.
We have hay prior experience in decommissioning a similar, but mere extensive facility in 1975-1976 with no unexpected problems.
7.2 plan Only a small' portion of the plant facilities (approx. 10%) is operated with any contamination present that would require cleanup upon,
decommissioning. The contamination is alpha type from non-irradiated enriched uranium.
Present sa:pling of the sanitary field shows that the requirenon:c of Table 7.1.9 Cptien 1 are met. Reference letter W. F. Kirk to W.
T.

SUMMARY
OF SOIL DISPOSAL OPTIONS 1.
Disposal of acceptably low concentrations (which meet EPA cleanup standards) of natural uranium, depleted or enriched uranium, and uranium ores with no restriction on burial method.
The concentrations specified for this option are acceptably 1cw withoUt restricting the method of burial. It is expected, however, that currently licensed operations will be conducted in such a manner as to minimize the possibility of soil contamination and when or if such occurs the contamination will be reduced to levels as low as reasonably achievable.
2.
Disposal of certain low concentrations of natural uranium 2nd depleted or enriched uranium (with no daughters present) when buried under prescribed conditions with no land use restrictions and no continuing NRC licensing of the material.
~
Under this cptien, burial will be permittcd enly if it can be
(
denenstrated that the buried materials will be stabilized ir place and not be transported away from the site. Acceptability cf the site for disposal will depend on tcpographical, geolegit-1, hydrolegical and meteoroicgical characteristics cf the site. At a ninimum, burial depth will be at least fcur feet belew the surface.

7.3 Cost Estimate UNC has experience in decommissicning and decontamination for unrestricted use of a similar facility. Its former care manufacturing shcps in New Haven, Conne :icut, were decontaminated i: 1975-1976 and released for unrestricted use by the U.S.
Nuclear Regulat:ry Cenmission en April 22, 1976.
Based en this recent actual experience, UNC estimates the cest, measured in current dollars, will not exceed $1,150,:00.
The New Haven decontamination w:rk included 9 truc}.1:2ds cf piping, Obsclete equipment, concreto, earth and ducting. In zur est'=ato f:r the M:n:ville program, we have provided for 18 truckl: ads, thcugh we expe:: it to be less than 6 truckloads.

UNC's decontamination experience.
2.
The fact that the New Haven operation had included processes no longer used and which created more severe contamination in the floor areas.
3.
The fact that the Montville Plant was designed for its purpose initially, with design features intended to minimize spread of contamination and facilitate cleanup on both a routine basis and final decommissioning. The New Haven buildings pre-existed and at were adapted to nuclear material manufacture.
The New Haven decontamination was performed by UNC employees under UNC supervisien.
7.4 Financial Assurances UNC considers that its depreciaticn policy, initiated in 1972 at tinc of its decision to consclidate Civision cperations in Men:ville.
provides full security f:r cost cf decc missioning.
Oopreciation for the facility is en an accelera cd basis, with the main buildings to be depreciated to a 201 residual value in 20 years under the terms of UNC's supplemental agreement with the Department of Energy of April 6,
1972. At the expiratien of the 20 year pericd.
straight line depreciatien will be charged until the boek value ;2 reduced to zero.
The facility is of =cdcrn, ene-s:Ory ccnstruction with excellent rail and highway access. Ecplacement ccst for the Montville bu;1 dings 1:
March 31, 1978 was $25,314,000 and net bcok value was $5,509,000. *NC considers that the excess of replacement cost cvor bco? "ilte pr:vides an ample suroty for the S1,180,000 decommissioning ccst, and that the accelerated depreciation =ethod, with book value to be reduced ::
zero, will provide continuing assurance of assets well in excess f
the small decommissicning cost.
