UNIVERSIT/ OF VIRGINIA DOCKET NO. 50-62 AMENDMENT TO AMENDED FACILITY OPERATING LICENSE Amendment No. 24 License No. R-66

1. The U.S. Nuclear Regulatory Commission (the Commission) has found that i A. The application for an amendment to Amended Facility Operating License No. R-66 filed by the University of Virginia (the licensee) on December 3,1998, as supplemented on December 10,1998, conforms to the standards and requirements of the Atomic Energy Act of 1954, as amended (the Act), and the regulations of the Commission as stated in Chapter I of Title 10 of the Code of Federal Regulations (10 CFR);

B. The facility will be operated in conformity with the application, the provisions of the Act, and the rules and regulations of the Commission; C. There is reasonable assurance that (i) the activities authorized by this amendment can be conducted without endangering the health and safety of the public and (ii) such activities will be conducted in compliance with the regulations of the Commission; D. The issuance of this amendment will not be inimical to the common defense and  !

security or to the health and safety of the public; E. This amendment is issued in accordance with the regulations of the Commission as i stated in 10 CFR Part 51, and all applicable requirements have been satisfied; and F. Prior notice of this amendment was not required by 10 CFR 2.105, and publication of  ;

notice for this amendment is not required by 10 CFR 2.106. l 1

2. Accordingly, the license is amended by changes to the Technical Specifications as indicated in the enclosure to this license amendment, and paragraph II.C.(2) of Amended Facility Operating License No. R-66 is hereby amended to read as follows:

(2) Technical Snecifications The Technical Specifications contained in Appendix A, as revised through Amendment No. 24, are hereby incorporated in the license. The University of Virginia shall operate the facility in accordance with the Technical Specifications.

3. This license amendment is effective as of the date of issuance.

i l

Obiectives: The objectives are to ensure that the shim rods are capable of performing their function and to establish that no significant physical degradation in the rods has occurred.

Snecifications:

4.1.1. Dron time Measurements i

4.1.2. Reactivitv Measurements l

l The shim rod reactivity worth shall be measured whenever the rods are installed l in a new core configuration.

i 4.1.3. Visual Insnections The shim rods shall be visually inspected annustly and when rod drop times exceed the limiting conditions for operation (Section 3.9 of these specifications).

Bases: The reactivity worth of the shim rods is measured to assure that the required shutdown margin is available and to provide means for determining the reactivity ,

worth of experiments inserted in the core. The visual inspection of the shim rods and  !

measurement of their drop times are made to determine whether the shim rods are capable of performing properly.

4.2. Reactor Safett Svste,m Applicability: These specifications apply to the surveillance requirements for the

reactor safety system of the reactor.

Obiective: The objective is to en:;ure that the reactor safety system is operable as required by Specification 3.2 by specifying frequency of tests, checks and calibrations. ,

I i

Specifications 4.2.1. Channel Tests i A channel test of each of the reactor safety system measuring channels shall be performed before each day's operation or before each operation extending more than one day.

4.2.2. Channel Checks A channel check of each of the reactor safety system measuring channels shall be i performed daily when the reactor is in operation, 4.2.3. Channel Calibration <

A channel calibration of the reactor safety r.ieasuring channels shall be performed serniannually.

Heat Balance 4.2.4.

The power range channels 1 and 2 shall be checked against a primary system heat balance at least once each week the reactor is in operation above 100 kW in the '

forced convection mode.

4.2.5. Reactor Safetv Channels Checks The above specifications (4.2.1 through 4.2.4) do not apply to the following reactor safety channels: power to primary coolant pump, manual button, header air pressure, pool water level monitor, and primary coolant flow, operation of these safety channels will be checked before each day's operation or before each operation extending more than one day.

Bases: The daily channel tests and channel checks will ensure that the safety channels are operable. The semiannual calibration will permit long term drift of the channels to be corrected. The weekly calibration of the power measuring channels will correct for drift and ensure operation within the requirements of the license.
