Direct ultimate disposal of spent fuel. Simulation of shaft transport. Proof of state-of-the-art of a conceptual design of a shaft hoisting equipment for a max. payload of 85 t (TA 2)

The reported conceptual design is the first of its kind worldwide for design payloads of this dimension, intended for the POLLUX containers. In order to prove the feasibility and thus the licensibility of the hoisting engineering concept, the first project task was to establish the design of the shaft hoisting equipment. The design of the essential components and sub-systems is based on the requirements of the existing safety guides and engineering codes determining the design quantities to be selected. According to a specific catalogue of criteria developed for this purpose, nine existing German hoisting facilities were selected as reference systems. The criteria are: establishment of a database allowing verification, site variance, payloads and rope loads, rope diameters, design type, number of ropes, performance conditions. The report explains the structural members, components and processes that could be tested and verified by existing reference facilities, and those which remained to be designed and verified in the completely new approach.
