SUBJECT:
Reactor Containment I Applicability This specification applies to the building in which the reactor is located.
i j Objective 1
! The objective is to assure adequate restriction to the accidental release of radioactivity to the environment.
j Specification
- a. The reactor and fuel storage facilities shall be enclosed in a containment i
i building with a free volume of at least 225,000 cubic feet.
4 j b. Whenever containment integrity is required, the containment ventilation exhaust '
l
! shall be discharged at least 55 feet above containment building grade level.
1
{ c. The containment building leakage rate shall not exceed 16.3 f t /3 min. (STP)
I with an overpressure of one pound per square inch gauge or 10% of contained volume over a 24-hour period from an initial overpressure of two pounds per i f
i square inch gauge. The test shall be performed by the makeup flow, pressure !
decay, or reference volume techniques.
- d. The containment building shall contain a secured fuel' storage room with the I
j key or combination under the control of the Reactor Manager. ] !

SUBJECT:
Containhent System s
Applicability This specification applies to the surveillance requirements on the reactor conttinment system.
Objective ,
s The 'objeckive of this specification is to reasonably assure proper reactor con tainmen t. ' s
, i Specification ,
- a. Tb'e containment building leak rate shall be verified annually, plus or minus four months. No special maintenance shall be performed just prior to the test.
4 ,
- b. The containment isolation system including each of its radiation monitors shall be tested for operability at monthly intervals.
Bases ,
Annual measurement of the containment building leak rate has proven adequate to insure that the building leak rate will remain within the design limits outlined in specification'4.2.c. No special maintenance will be performed prior to the ]
test so that the test will verify the historic integrity of the containment. The reliability; of the isolation ' system has proven that monthly verification of-its proper operation is sufficient to assure operability.

SUBJECT:
Administration (continued)
The Reactor Advisory Committee and its subcommittees are to maintain minutes of meetings in which the items considered and the committees recommendations are recorded. Independent actions of the subcommittees are to be reviewed by the parent committee at the next regular meeting.
A quorum of the committee or the subcommittees consisting of at least fifty percent of the appointed members must be present at any meeting to conduct the business of the committee, or subcommittee.
The Reactor Advisory Committee shall meet at least once during each calendar quarter.
A meeting of a subcommittee shall not be deemed to satisfy the requirement of the parent committee meeti g quarterly.
- e. Any additions, modifications or maintenance to the systems described in these specifications shall be made and tested in accordance with specifi-cations approved by the U.S. Nuclear Regulatory Commission. ]
- f. Following a favorable review by.the U.S. Nuclear Regulatory Commission, ]
the keactor Advisory Committee, or the Reactor Facility Management as appropriate and prior to conducting any experiment, the Reactor Manager shall sign an authorizing form which contains the basis for the favorable review.

SUBJECT:
Administration (continued)
- g. In addition to those otherwise required under this license and W icable regulations, the following records will be maintained:
(1) Reactor operating records, including power levels and periods of operation at each power level.
(2) Records showing radioactivity released or discharged into the air or water beyond the effective control of the licensee as measured I
at or prior to the point of such release or discharge.
(3) Records of emergency shutdowns and inadvertent scrams, including reasons for emergency shutdowns.
J (4) Records of maintenance operations involving substitution or replace-ment of reactor equipment or components.
(5) Records of experiments installed including description, reactivity worths, locations, exposure time, total irradiation and any unusual events involved in their performance and in their handling.
(6) Records of tests and measurements performed pursuant to these specifications.
, h. The following reports shall be made in addition to those otherwise required under applicable regulations:
(1) The U.S. Nuclear Regulatory Commission shall be informed of any ]
incident or condition relating to the operation of the reactor which prevented or could have prevented the
