' DESCRIPTION OF CHANGE l
j
. Indian Point Station Unit No. 1 Technical Specification 4.1.8.1.b and Indian l
Point Station Unit No. 2 Technical Specification 6.12.1.b state that doors to High Radiation Areas in which the intensity of radiation is greater than 1000 mrem /hr shall be locked to prevent unauthorized entry, and that the keys shall be maintained under the administrative control of the Senior Watch Supervisor on duty.
l It is proposed that the keys for the doors of High Radiation Areas in which j
the intensity of radiation is greater than 1000 mrem /hr be administratively controlled by the Radiation Protection Manager and/or the Senior Watch Supervisor on duty.
i In past practice, key control for. personnel other than watch personnel has been delegated to the Radiation Protection Manager by the Senior Watch j
Supervisor.
This proposed change would negate the need for the formal j
delegation. Control of High Radiation Area Keys by the Radiation Protection Manager and/or Senior Watch Supervisor is in accordance with Standard Technical Specification philosophy.
BASIS FOR NO SIGNTFTCANT HAZARDS CONSIDERATION DETERMINATION l
The proposed change does not involve a significant hazards consideration since:
1.
There is no significant increase in the probability or consequences of an accident.
i This is an administrative change being proposed by the the Company.
i The change clarifies current implementation of Technical Specifications, the same criteria for high radiation access as are l
currently in place and as previously evaluated would still be met under the proposed change.
2.
The possibility of a new or different kind of accident from any previously analyzed has not been created.
The proposed change is purely administrative in nature.
The change does not modify plant configuration or operation, and therefore, the identical postulated accidents as analyzed prior to this submittal are
[
the only ones that required analysis and resolution. Nothing would be added or removed that would conceivably introduce a new or different kind of accident mechanism or initiating circumstance than that previously evaluated.
l 3.
There has been no reduction in the margin of safety.
All safety criteria previously evaluated are still met at the same margins since the change is simply a
clarification of the l
administrative control of High Radiation Area keys. Both the Radiation Protecti 7 Manager and the Senior Watch Supervisor are qualified by training to control these keys.
l The proposed change has been reviewed by the Station Nuclear Safety l
Committee, which concurs that the change does not represent a significant hazards consideration.
