CHEMISTRY Module 3 Reactor Water Chemistry

EFFECTS OF RADIATION

ON WATER CHEMISTRY (SYNTHESIS)

Radiation synthesis is a process that takes place in the reactor coolant system. This phenomenon is limited to the reactor coolant system because of the high flux (radiation) levels that exist in the core region and further complicate chemistry control of the reactor plant.

EO 1.1DESCRIBE the process of radiolytic decomposition and recombination of water.

EO 1.2DESCRIBE the process of radiolytic decomposition and recombination of nitric acid and ammonia.

EO 1.3STATE the advantage of maintaining excess hydrogen in reactor water.

EO 1.4STATE the three sources of radioactivity in reactor water and each one's decay product.
