20555 Attention:
Mr. Robert W. Reid, Chief Operating Reactor Branch #4 Re:
License No. R-66, Docket No. 50-62
Dear Sir:
This letter provides additional information in support of our March 9, 1977 request for approval of an amencment to extend the expiration date of license R-66 covering the University of Virginia Reactor (UVAR).
This in-formation provides a partial response to the license renewal items identified in the enclosure to your 1ctter of October 16, 1978.
Specifically, this letter provides additional general information concerning the University of Virginia and information concerning environmental aspects related to the operation of the UVAR as requested by sections A.1 and A.2 of your letter.
This additional information is provided in the following sections:
A. Additional Information Concerning Financial Consideration Related to the UVAR as Delineated in 10 CFR 50.30(f). and Requested in Review Item A.1(f)
A.1.(f)(1) The most recently published annual statement of operations of the University of Virginia.
The most recent annual financial report for the University is included as Attachment A.
The State supported budget for the Nuclear Reactor is shown in Attachment B.
Additional inform-ation which shows that the Reactor Facility budget is about 0.2%
4 of the University budget for educational purposes is provided in Attachment C.
A.I.(f)(2) Estimated annual costs to operate the reactor for the license renewal period.
The State funded budget for operating the reactor for 1978-79 is $126,304.
An annual increase of 7% has been used to estimate the budget figures below:

$125,000 1987
$232,000 1978 126,000 1988 248,000 1979 135,000 1989 265,000 1980 144,000 1990 284,000 1981 154,000 1991 304,000 1982 165,000 1992 325,000 1983 177,000 1993 348,000 1984 189,000 1994 372,000 1985 202,000 1995 398,000 1986 216,000 1996 426,000 Total for 20 years $4,835,000.
This budget represents less than 1" of the State supported budget for the University.
The University has supported the reactor facility since its inception in 1958.
There is every expectation that the State will continue to support the reactor at this level.
This intent is cicarly shown in the letters from the Dean of the School of Engineering and Applied Science and from the University Comptroller enclosed as Attachment C.
A. I. (f). (3)
Estimated costs of permanently shutting down the reactor.
Total 1)(a) Remove, package, ship and reprocess 85 fuel elements.
Reprocessing charge 0 $1000/
element.
$85,000 Shi.pping charge $10,000/ shipment, 20 elements / shipment 40,000 (b) Labor. I month 8,000

and sources 2 drums 140 Labor, 2 days 800 940

- 6) Disposal of demineralizers and enarcoal 10 drums 700 Labor, 2 days 800 1,500
- 7) Cican pool, decontaminate and paint Labor, 1 month 8,000 8,000 Total
$159,800 (a) Includes the cost of removing all fuel presently at the reactor.
In the past, reprocessine and shipping costs have been partially supported by DOE (AEC) through the reactor sharing program.
We anticipate partial relief from these costs in the future.
(b) Labor costs are based on a State supported budget for personnel of $100,000 in 1978.
Labor times represent in-volvement of the entire State supported reactor staff.
(c) Waste materials packed in 55 gallon drums and disposed as dry waste.
The type of permanent shutdown contemplated is the decommis-sioning of the UVAR and the CAVALIER reactors to the point that the space they now occupy can be released for unrestricted use.
The funds required to permanently decommission the reactors will be provided for in the regularly budgeted State appropriations or by University overhead funds when necessary.
A.1. (f). (4) An estimate of the annual cost to maintain the shut down facility in a safe condition.
It is anticipated that the facility will be decontaminated so that it can be released for unrestricted use.
In that event the building would probably be used for other research activities of the University so the question of annual maintenance costs is not relevent.
B. Additional Information Concerning Environmental Considerations Related to the UVAR as Requested in Review Item A.2. (f).
A. 2 ( f) (la)
Information concerning the reactor coolant system pressures.
The pressure of the primary and secondary coolant at the inlet and outlet of the heat exchanger was recently measured and is tabulated in the tabic provided below.
These data show that the pressure on the secondary side is higher than the pressure on the primary side

Information concerning secondary cooling system discharge.
The only loss of water from the secondary cooling system during normal operation is due to evaporation to the atmosphere.
Any excess water resulting from overflow or draining of the secondary side for maintenance will go to the pond located near the reactor facility, as discussed in sections 4.5 and 4.8 of UVAR-18 Part I which is the UVAR Safety Analysis Report.
A.2.(f)(2)
Information concerning radioactivo effluents.
The direct radiation IcVel of liquid effluents, which are pre-dominantJy liquid effluents from demineralizer regeneration is less than 1 mr/hr en contact.
Effluents are stored in underground hold-up tanks and eventually released with water from a hold-up pond as a dilutant.
Releases over the last several years are as follows:
Activity Total Volume Average Specific Year (microcuries)
(gallons)
Activity (uci/ml) 1974 320.0 10,050,500 8.4 x 10~
1975 259.8 12,818,000 5.4 x 10~
1976 324.4 10,516,000 8.6 x 10
-8 1977 474.0 5,511,000 2.3 x 10 A.2.(f)(3)
Information concerning the disposal of samples.
Disposal of radioactive waste, including samples, is discussed in sections 7.6 and 7.7 of UVAR-18, Part 1, the Safety Analysis Report.
Presently, solid waste disposal is contracted to Tcledyne, Inc.
A. 2. (f)(4)
Information concerning release of radioactive materials to unrestricted areas.
All solid spent activated samples are co11ceted as waste and shipped to a burial site, therefore no activity is released to
Letter to Director of Reactor Licensing December 18, 1978 Page 5 A. 2. (f) (4)
(Continued) unrestricted areas from these sampics.
The concentration and activity of radioactive liquids is provided in Item 2, above.
Total Argon-41 releases during the past several years have been as follows:
Ar from Ar from Year Reactor Operation Sampic Activation 1974 314 millicuries 175 millicuries 1975 230 millicuries 220 millicuries.
1976 277 millicuries 165 millicuries 1977 705 millicuries 0.5 millicuries C. General Information Concerning the University as Delineated in 10 CFR 50.33 as Requested in Review ltems A.1. (c) through A.1. (e).
The requested information which relates to the purpose and officers of the University of Virginia and a list of other NRC licenses held by the University of Virginia is included as Attachment D.
It should be noted that the University of Virginia does not own or oper-ate a criticai experimental facility at Lynchburg, Virginia and therefore al1 licenses held by the University of Virginia are related to activities in Charlottesville, Virginia.
Nineteen copies of Attachment D, which includes our original request to extend the license expiration date, have been included as requested by 10 CFR 50.30(c)(1)(ii) and review item A.2. (c)(1)(ii).
In addition, this information responds to review item A.2. (d) which specified the information to be contained in applications for reactor operating license as delineated in 10 CFR 50.30 (d).
This letter provides our response to all of the review items in Section A.I and A.2 in the enclosure to your October 16, 1978 letter.
As previously agreed, we will provide our response to the remaining items by January 19, 1978.
Sincerely, Attachments
