Subject: Powernet: Environmental monitoring systems question
San Onofre would appreciate information on any sites that have environmental
monitoring stations that have been or are established for access to the data by
their external stakeholders (cities, counties, state, etc). In particular:
1. what kind of environmental monitoring system is it? eg. PICs, air
samplers, NaI rad monitors, GeLi or equivalent rad monitors
PICs (Pressurized Ion Chambers, Reuter Stokes model RSS-131)
1. was the monitoring system installed in response to stakeholder request?
Yes, within E-Plan
1. How many monitoring stations?
13 (plus 2 spares)
1. what was the basis for selecting the location of the monitoring stations?
(a) distance from the plant or (b) receptor locations or (c) site boundary
Yes (a, b, and c) including X/Q sectors
1. who maintains the system? (calibration, sample change out)
Our TCOM group. We send a "standard" back to the vendor
annually for calibration and then do a verification comparison cal in the field
(using sources) for the remaining 13 units.
1. are the data available to stakeholders in real time? If so, are the data
reviewed for QA/QC checks before it becomes available externally?
Yes, at our Emergency Operations Facility. No.
