Auxiliary Board Project

Auxiliary Board Operation

1.
Plant Operators control the gathering, treatment, and discharge of
hazardous waste products created during operation of the DCPP U1 and U2
power plants.

2.
Liquid Radwaste System (LRW) collects and processes the radioactive liquid
wastes generated during plant operation.

3.
Gaseous Radwaste System (GRW) collects and processes the radioactive
gaseous wastes generated during plant operation.

4.
Chemical and Volume Control System (CVCS) collects and processes borated
radioactive effluents from the Reactor Coolant System.

5.
Reduces the activity to levels acceptable for discharge to the environment.
