Near-surface long term storage facility for storing heat-generating radioactive waste with passive heat dispersion and method for storing in a long term storage facility

摘要

The near-surface long-run intermediate storage (20) has a base plate (4), a side wall (3) and a covering (1), which limits a storage area, where a fluid conveying device (5) is arranged in the storage area with a chimney section (6) having a fluid inlet end (6a) and a fluid outlet end (6b). A base section (7) partial surrounds heat-generating radio active waste arranged in a container (10). The fluid conveying device defines a flow path (A) for heated fluid and another flow path (B) for cooled fluid, and supplies heated fluid to the covering through the fluid outlet end. An independent claim is included for a method for near-the-surface storage of heat-generating radio-active waste.
