BWR Operational Chemistry

(Class Sessions: ~28 Hours)

Course Description

The BWR Operational Chemistry course was developed by NWT to assist plant and corporate chemistry personnel in the following areas:

  1. Understanding the basis of the selected chemistry control program approach.
  2. Identifying the presence of, or trends toward, abnormal chemistry conditions.
  3. Diagnosing problem causes.
  4. Developing timely and cost effective corrective actions.

The course has been developed by senior NWT personnel who have been involved in BWR and PWR water chemistry, corrosion, water treatment, and activity transport control for 30 or more years. Their experience base has been complemented by consideration of the underlying chemistry and engineering principles in each area of instruction.

The course is intended for BWR chemistry personnel involved in evaluating options for BWR chemistry control, assessing operational chemistry and radiochemistry data, identifying and diagnosing chemistry related problems and developing corrective actions.
