Synopsis:

Subject makes students familiar with safety analyses carried out during radioactive wastes (RAW) handling and spent nuclear fuel (SNF) handling. More specifically, safety analyses aim at transport, storage casks and disposal canisters for RAW and SNF and further at storages and deep geological repositories (DGR) of RAW and SNF. In the frame of lectures, students get overview about analyses aimed at determination of radioactive inventory of RAW or SNF, assurance of subcriticality, shielding, retention system, and heat transfer (thermo-physical characteristics) from assembly packages, storages, and DGR of the RAW or the SNF, searching of transport paths and mechanisms of radioactive isotopes releases into environment, releases of radionuclides at normal or abnormal and accident conditions during handling with RAW and SNF.

Requirements:

Syllabus of lectures:

1. Legislative requirements applied onto safety analyses in frame of handling with RAW and SNF. (1 lecture)

2. Determination of radionuclide inventories of RAW and SNF. (2 lectures)

3. Analyses of the package assemblies (transport and storage casks, disposal canisters): criticality analyses, shielding, activity retention system, thermo-physical analyses. (3 lectures)

4. Analyses of RAW and SNF storages and repositories (3 lectures): criticality analyses, shielding, activity retention system, thermo-physical analyses.

5. Analyses of transport paths and mechanisms of radionuclide releases into the environment. (2 lectures)

6. Releases of radionuclides at normal, abnormal and accidental operational conditions. (2 lectures)
