Description

Spent fuel hand-operated tipping machine maintenance back test device

Technical Field

The invention relates to spent fuel conveying, in particular to a test device for a spent fuel hand-operated tipper after maintenance.

Background

The two heavy water reactor nuclear power units of the Qinshan nuclear power are only two heavy water reactor units in China at present, the advantage of the heavy water reactor is that materials are changed without stopping the reactor, but as the storage capacity of a material changing pool is limited, spent fuel must be built for temporary dry storage so as to meet the requirement of stable operation of the heavy water reactor nuclear power station. The method mainly comprises the steps of horizontally storing the spent fuel under water, turning the spent fuel to 90 degrees through a tipper, then grabbing the spent fuel, and after the tipper is subjected to water outlet maintenance, the spent fuel cannot be connected with a driving mechanism, so that related tests (balance, balance weight, in-place lifting and the like) cannot be performed, and in order to ensure the maintenance quality, all parameters meet requirements, a set of hand-operated driving test device must be developed to ensure that all parameter indexes meet the requirements after the tipper is maintained.
