sensors shall be qualified
,in accordance with
, Regulatory Guide 1.89 (NUREG-0588).
Seismic Qualification in accordance with Regulatory Guide 1.100 shall be provided when the instrumentation is part of a
safety related system.
(Reference Independent Design Review of the PVNGS Instrumentation and Controls
- Systems, June 17-18,
The components qualified seismic 2
are given in the reference.
This complies with the Regulatory Guide.
(2)
Vent flow calculations are performed using the design flow of
- heating, ventilation, and air conditioning fans versus measured flow.
(3)
Heat removal by containment fan heat removal system indication is accomplished using the containment atmospheric temperature monitors listed with R.G. 1.97.

RESPONSE
TO REGULATORY GUIDE 1.97 REQUIREMENTS NOTES PVNGS utilizes two ranges of vertical temperature difference (delta temperature).
One range is
-6o to
+6oF with the portion from
-5 to
+5 F
being calibrated.
The range
- from,
-6 to
+18 F, is for extended range indication beyond
+6 F.
Tnus PVNGS meets the ranges required by R.G.1.23 (normalized for the PVNGS tower height) for the Pasquill Categories indicated that are used for the atmospheric stability class calculations.
The PVNGS delta temperature range has also proven to be adequate and reliable; evidenced by historical data at the location.
