- 1 Reason and Basis for Chance NUREG-0737, Item II.F.'l-1 required the installation of noble gas monitors with an extended range designed to function during nortaal operation and~ accident conditions.
l This requirement was met by modifying = existing sampling arrangements as'well as by installing new equipment.
1.
The noble gas effluent monitoring system, including the high range PVS noble gas monitor, and four main steam line l
monitors.has been evaluated by the Staff for conformance with NRC~ criteria and determined to meet the requirements
- contained in the NUREG.
A description of the installed equipment and the Staff's evaluation is provided in Reference (c).
I Safety Consideration This change is requested in order to add requirements for.the noble gas effluent monitoring equipment installed.to meet the requirements of NUREG-0737, Item II.F.1-1.
-This-change incorporates the operability and surveillance requirements for the approved equipment in accordance with model Technical Specifications provided by the Staff in i
As such this proposed change would not
.l.
Involve a significant increase in the probability or consequences of an accident previously evaluated.
This change incorporates equipment used to-assess plant conditions and designed to function during accident conditions.
The installed equipment has been determined' l
to conform to Staff criteria.
This change will not I
increase the probability or. consequences of an accident previously evaluated.
2.
Create the possibility of a new or different kind of accident.from any previously evaluated.
This change is administrative in nature and incorporates limitations and i
surveillance modeled from Staff guidance, the implementation of which will not create the possibility j
of a new or different kind of accident.
The installed l
equipment is in response to the requirements of NUREG-0737.
3.
Involve a significant reduction i n a margin of safety.
As a new Technical Specification there is no reduction in a margin of safety.
The noble gas monitors are utilized to assess plant conditions, during and following an accident.
These monitors are operable in Modes 1-4, but are not required for safe shutdown of the plant.
In case of failure of the monitor, appropriate actions to be taken in a reasonable period of time have been delineated in accordance with Staff criteria.
