Abstract
A shield for use with nuclear reactor systems to attenuate radiation resulting from reactor operation. The shield comprises a container preferably of a thin, flexible or elastic material, which may be in the form of a bag, a mattress, a toroidal segment or toroid or the like filled with radiation attenuating liquid. Means are provided in the container for filling and draining the container in place. Due to its flexibility, the shield readily conforms to irregularities in surfaces with which it may be in contact in a shielding position.
Claims14
In a nuclear reactor system comprising a reactor vessel, a biological shield surrounding said vessel and spaced therefrom, said vessel and said shield having adjacent upper surfaces defining an upper opening for the space between said vessel and said biological shield, the improvement comprising a radiation shield covering said upper opening, said radiation shield comprising a reusuable flexible container, and a liquid radiation attenuating material in said container.
A radiation shield for use in installations containing sources of radiation, comprising a reusable flexible container, a liquid radiation attenuating material in said container, and inlet and outlet means for filling and draining said container.
A method of shielding radiation comprising the steps of emplacing a reusable flexible container in the line-of-sight between a radiation source and an area to be shielded from radiation, and filling said flexible container with a liquid material which attenuates radiation.
