Reactor spent fuel water basins for spent nuclear fuel

摘要

The invention relates to nuclear engineering, in particular to the storage of spent nuclear fuel, having slotted beams of the ceiling and can be used in nuclear reactor spent fuel pools. Object of the proposed technical solution is to increase the efficiency of use of the pool volume by increasing SNF storage density by partial transition to bespenalnoe storage of SNF. The essence of the claimed technical solutions consists in the fact that in the reactor spent fuel water pool for spent nuclear fuel, comprising a beam overlap, removable supports with bearing seat for the suspension with the spent nuclear fuel arranged in mezhbalochnyh slits parallel rows suggested planting nest in adjacent rows to shift the relative each other, and the distance between the centers of the landing slots determined from the relation: H L≥D where L - distance between centers of landing jacks [cm], n - mezhbalochnoy slit width, [ cm] D - outside diameter of the spent fuel assembly taking into account the possible curvature height [cm].
