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
exchange efficiency.
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.
