|
Term
| STATE the advantage of maintaining excess hydrogen in reactor water. |
|
Definition
Excess hydrogen is added to suppress the decomposition of reactor water.
To prevent the formation of oxygen in reactor coolant, hydrogen is added. |
|
|
Term
| STATE the four sources of radioactivity in reactor water and each one’s decay product. |
|
Definition
|
|
Term
| STATE the parameters controlled for reactor water chemistry and the reason and method for controlling each parameter. |
|
Definition
|
|
Term
| STATE the possible effects of Fuel element failure on core chemistry conditions. |
|
Definition
| Fuel element failure causes Fission products release path to reactor coolant, and lower ion exchange efficiency. |
|
|
Term
| STATE the possible effects of introduction of air on core chemistry conditions. |
|
Definition
Introduction of air:
Hydrogen Depleted => Lowering pH, Loosens Corrosion Film (Leading to a Crud Burst), Higher Radiation Levels, and raising Conductivity. |
