Docket 50-223 i License . R-125 United States Nuclear Regulatory, Commission  !

Ilarold Denton, Director Division of Reactor Licensing Washington, D.C. 20555 Re: 10CFR50.33 and 10CFR50.75 Decommissioning Funds Gentlemen:-

.The Code of Federal Regulations,10CFR50.33(k)(2), requires that all -j operating reactors' comply as follows:

"On or before ' July- 26, 1990, each holder of an operating license for a production or utilization facility.:in effect on July 27,1990, shall submit information in a form of a report as described in paragraph '

50.75 indicating .how reasonable assurance will be provided that funds will be available to decommission the facility."

The section of.10CFR50.75 that applies to the University of Lowell Reactor is 10CFR50.75 (e)(2)(iv) which reads as follows:

In the case of federal, state, or local government licensees, a  !

statement of intent containing a cost estimate for decommissioning, '

and indicating that funds for decommissioning will be obtained when necessary."

- . 4 This letter. serves as a statement of intent required by 10CFR50.75 (e)(2)(iv). The cost estimate for decommissioning the University of Lowell Reactor in 1990 dollars is $1,450,000. The reactor is sup-ported by the University of Lowell,' which is a state University, '!

Funds for decommissioning the University of Lowell Reactor will be requested of the General Court of the' Commonwealth ~ of i Massachusetts when necessary._ ,

University of Lowell Reactor Decommissioning Plan July, 1990 University of Lowell Reactor Decommissioning Plan  ;

The goal in decommissioning the University of Lowell Reactor is to return the reactor building to a normal condition. The following criteria applies:

1. . No radioactive material.

2. No contaminated material.

3. No reactor parts or equipment.

To realize the above, the walls, roof, and rooms can remain but all movable parts and equipment as well as the reactor pool must be ,

completely removed.

I. Iligh level Radioactive Material The following would be shipped to proper facilities .(in order of intensity)

A. Used fuel elements. ,

32 elements - 2 BMI-1 shipments B. Graphite Reflectors.

1 BMI-l shipment C Grid plate.

D. Cobalt-60 source.

4 shipments using appropriate cask.

E Beamport ends.

F. Lower bridge structure components.

G Holders - plugs - misc. experiment pieces.

H. Misc. Iow level parts and pieces.-

University of Lowell Reactor- Decommissioning Plan J uly, 1990 J. Fork truck K Misc. parts and pieces.

The items above would require significant assistance from outside contractors as well as health physics surveillance for monitoring and shipping, ,

i Decommissioning the University of Lowell Reactor does not in- l clude removal of radioactive and contaminated material from the i Radiation Laboratory. Should that be desired, the following major items would have to be removed.

A. Cobalt-60 irradiator.. I C Five waste retention tanks, piping, and concrete floor in area.

E Exhaust hoods.  !

F. Numerous radioactive sources.- ,

Coll We have used NUREG CR1756 to estimate the cost of decom-missioning.

1. NUREG CR 1756 - Technology, Safety and Costs of Decommissioning Reference Nuclear Research and Test Reactors.

The NRC method, called DECON, calls for immediate removal of i all radioactive material and release of the prope.ty for i unrestricted use, it does not include fuel and waste shipment Costs. I Cost = $850,000 in 1981 or '

$850,000 +(1.05) 9 = $1.32x106 in -1990 dollars When one includes shipment of fuel,1 Cobalt-60 and waste that were not included, it would appear that a reasonable cost estimate is $1.45x106. This includes ~ a 25% contingency.

-. July, 1990 Time Frame 4 NUREG CR 1756 estimates one year pre planning and nine months to decommission.  !

It would appear that because of our limited staffing a reasonable time estimate would be two and one half to three years.
