Containers for storage and transportation of SNF
At present nuclear industry uses a developed family of containers "COCON-BLOK" for storage and transportation of spent nuclear fuel (SNF) and for storage of solid radioactive waste. The transport packaging assembly includes an SNF storage package and a damping device for protecting it. The assembly includes a metal-concrete container, a spacing grid for SNF placement, ampoules or SNF covers.
The use of double-purpose concrete containers provides:
- modularity and stage-by-stage organization of temporary storage facilities and the necessary set of containers as micro-storages;
- possibility of sending SNF without reloading from the territory of temporary storage facilities to processing or disposal sites;
- shortest terms for the construction of temporary solutions;
- identification of contents of the container which was stored and moved through the control and accounting, ease of keeping the accounting and storage systems;
- minimum degree of fuel degradation in dry conditions of storage and development of defects in spent or damaged fuel assemblies;
- passive removal of residual heat from stored fuel;
- low dose loads on personnel during SNF container loading / unloading operations and container operation;
- reliable protection from environmental pollution;
- absence of cooling water, which eliminates the leakage of radioactive water.
