- 1. Introduction ,
Where applicable, these Technical Specifications follow the format of the American National Standard ANSI /ANS-15.1-1990.
4 1.1 Scope
, These Technical Specifications apply to all portions of the Plum Brook i
Reactor Facility (PBRF), with the exception of the Mock-Up Reactor (MUR) which is separately licensed. The PBRF contains a non-operable test reactor, its support facilities, and its inventory of radioactive materials generated as a res' ult of previous operations. The reactor was shut down in 1973 after 98,000 megawatt days of operation.
l The radioactive inventory, with the exception of distributed radioactive material existing as contamination within process systems and laboratories, is stored in four locations. These are located inside of the Containment Vessel, in the Reactor Building Canal G, in the Hot Laboratory, and in the Waste l Handling Building. The PBRF contains no fuel and no special nuclear material. ,
4 1.2 Application These Technical Specifications govern the condition of the National l
! Aeronautics and Space Administration's PBRF in the Possession-Only status.
l The PBRF is described in the Design Manual and Hazard Analysis submitted for the original PBRF license and now contained in Docket No. 50-30. The l PBRF systems which are radioactive, contaminated, or required to maintain a protected safe storage condition, are covered in these Technical Specifications. These systems are listed in the Table of Contents for these I
Technical Specifications under the Requirements Section (Items 2.2 through 2.14 and 2.21 through 2.23).

- 1. Introduction l l
1.1 Scope These Technical Specifications apply to portions of the facility which contain a nonoperable research reactor, its support facilities, l and its inventory of radioactive material generated as a result of previous operations. The Mock-Up Reactor (MUR) was shut down in 1973 after approximately 200 kilowatt-days of operation. The MUR contains no fuel and no special nuclear material. Therefore, j these Technical Specifications apply only to systems, components, or areas which are radioactive, contaminated, or are needed to maintain a protected safe storage condition.
1 I
I 1.2 Definitions 1.2.1 General !
l Authorized Entry - Entry by people authorized by management l with a legitimate need to enter the PBRF who have knowledge of
! the conditions, the hazards, and proce'dures of the facility or who are accompanied by someone with this knowledge. i Kept Dry - The condition of an area which is normally dry, or ,, i drained and mopped dry as soon as practical when becoming inadvertently wet.
Nonocerable - The condition of a component or system which has been intentionally disabled to prevent it from performing its intended function.
Protected Safe Storage - The custodial state of undefined duration characterized by physical and procedural access control and periodic monitoring, maintenance and inspection.
Shall- The word "shall" is used to denote a requirement.
1
r 1 l j 1
Surveillance Frequency - Unless otherwise stated in these specifications, periodic surveillance tests, checks, calibrations, and examinations shall be performed within the specified surveillance intervals. In cases where the elapsed interval has exceeded 100% of the specified interval, the next surveillance interval shall conunence I at the end of the original specified interval. Allowable surveillance intervals, as defined in ANSI /ANS 15.1 (1990) shall not exceed the following:
l 1. Annual (interval not to exceed 15 months)
