Reactor Water Chemistry
The important information in this chapter is summarized below.
Chemistry Parameters Summary
Table 1 provides a summary of the parameters, why they are controlled, and the
methods of control.
The following abnormal chemistry conditions are discussed:
Injection of air will cause the hydrogen inventory to become depleted, which
in turn can lead to a pH swing towards the acidic end. This reduced pH
leads to a loosened corrosion film hence a crud burst. The crud burst causes
higher radiation levels and an increase in conductivity.
Fuel element failure allows large amounts of fission products a possible
release path to the reactor coolant. This could lead to a lowered ion
Resin overheating results in the decomposition of the resin. The products
of the decomposition can seep into the reactor coolant and affect the
chemistry in several ways. A few of the common products and their
resulting influence on the chemistry is discussed.
