- 5. Does the licensee perform any other onsite monitoring (e.g. soil sampling) to identify unexpected, radioactive releases?
No program exists specifically for this purpose. However, soil excavated inside the radiological restricted area is monitored prior to removal from the area for gamma emitters. Also once per 3 (three) years soil samples are analyzed for gamma emitters and Sr-89/ 9 0 at one environmental station in the owner-controlled area and two environmental stations at the owner-controlled area boundary.

Revision 40-09/30/04 NAPS UFSAR 9.2-35 scheduled basis to obtain even wear. Following installation of spare parts or piping modifications, visual inspections are conducted to confirm normal operation of the system.
9.2.2.8 Instrumentation Application The'Mystem is monitored from the main control room by indicators that display the following data:
- 1. Pump, discharge pressure.
2.' Temperature and flow in the supply headers from the component cooling heat exchangers.
- 3. Temperature in the return headers from the residual heat removal heat exchangers.
- 4. PlFiofrom the reactor coolant pump thermal barriers.
- 5. Temperature in the return headers at the pump suction.
- 6. Radioactivity in the component cooling water heat exchanger constant-flow vents.
LAIl indicators for pressure, temperature, level, and flow are provided on a general basis.
Certain selected temperatures are sensed by thermocouples whose output signals are fed into the comp*ter, ystem, thus providing full-time scanning and alarming.
Air1operated trip or motor-operated valves are installed on the outlet headers from those componelnts served in the reactor coitainment. A check valve or air-operated trip valve is installed in the inl6t header at the containment for the components served in the reactor containment.
9.2,3j: ater Supply and Treatment Systems 9.2.3.1' Domestic Water System The domestic water system consists of ground wells dug at various locations on site.
Periodic samples are collected at the discharge of each well pump to ensure that the wells provide a safe, 4& approved water supply to the station facilities.
Each well has its own structure, hydropneumatic tank, pump, and compressor. Pressure is sustained in the system by maintaining the proper water to air ratio in the individual hydropneumatic tank via pressure and level controllers. Well pumps are sized to provide adequate make-up to the system without excessive draw down to its respective well. As an added pm. ection, well level is ensured via level switches, to mitigate the chances of pumping a well dry and damaging the submersible pump. Water is supplied from each well to its respective hydropneumatic tank, which acts as a surge volume and pressure source for the header. Each hydropneumatic tank discharges to a common header. For maintenance evolutions, each hydropneumatic tank is isolable and bypassable to allow service directly from the well pump. The common underground piping is regionally isolable to allow for isolation of any well house from the system without isolating water supply to the facilities in that area.
