Department of Nuclear Chemistry

Synopsis:

The course deals with the principles of water technology and chemistry of nuclear power plants (NPP). The main attention is paid to the individual technological operations used to the purification of feeding waters and cooling circuits’ waters and of all liquid and gaseous radioactive media encountered in NPP. The technological operations used for the treatment of wastes and the corrosion problems of the construction materials are discussed in detail, too. Students will be able to evaluate and to assess the effect of technological parameters on the processes of water treatment and decontamination.

Requirements:

Syllabus of lectures:

1.Mechanical processes for the treatment of waters (filtration, sedimentation, and centrifugation). The principles of physical-chemical and chemical processes for the treatment of waters, sludge and gases (water clarification, ion exchange, evaporation, solidification of radioactive wastes, and purification of gases).

2.Ion exchangers (structure, the basic types and properties, application for the water treatment, the types of apparatus and the realization of working cycle).

3.The radiochemical specialty of some operations of NPP (contamination of primary circuit water by fission and corrosion products and by the products of important radiochemical reactions).4.The review of treatment processes used in NPP (the simplified technological diagrams).

5.The treatment of non-radioactive waters and sludge (supplementary and cooling water, condensate from secondary circuit, neutralization, dewatering of sludge, etc.).

6.The treatment processes of the primary circuit cooling water

7.The purification of water from the storage pools with irradiated fuel.

8.The purification of sludge from steam generator

9.The purification of liquid wastes from theregeneration and washing of ion exchangers, of the leakages from primary circuit, etc

10.The purification and the storage of boric concentrate. The purification of radioactive gaseous wastes

11.The treatment and deposition of radioactive wastes (liquid and solid wastes)

12.The issuesof corrosion (the fundamentals of corrosion, the types of corrosion and anti-corrosion measures;the corrosion problems in primary and secondary circuits; experimental methods for the study of corrosion).
