US 5,848,112 A · Method of transporting nuclear fuel substance

Abstract

There is provided a method of transporting a nuclear fuel substance capable of increasing an amount of storing the nuclear fuel substance of a transport vessel by lowering the neutron effective multiplication factor by arranging neutron absorber plates among a plurality of nuclear fuel storing drums for storing the nuclear fuel substance, or at the inside of the respective nuclear fuel storing drums in transporting the nuclear fuel substance. According to the present invention, in transporting the nuclear fuel substance by containing a pile of the plurality of nuclear fuel storing drums in series for storing the nuclear fuel substance in the transport container along the vertical central axis of the transport container having substantially the bottomed cylinder shape, the neutron absorber plates each including a component for absorbing neutrons are interposed among the respective nuclear fuel storing drums on planes orthogonal to a vertical central axis of the transport container.

A method of packing drums containing nuclear fuel in a generally cylindrical, insulated transport container, each of said drums including a lid and said transport container including a main body formed by a bottom wall and a side wall, and a cover, said main body defining a central axis, said method comprising the steps of:

(a) placing a first drum containing nuclear fuel in the main body of said transport container above the bottom wall thereof,
(b) placing a first neutron absorber plate in the main body of said transport container above said first drum so as to extend generally transversely to said central axis,
(c) placing a second drum in the main body of said transport container above said first neutron absorber plate,
(d) placing a second neutron absorber plate in the main body of said transport container above said second drum so as to extend generally transversely to said central axis, and
(e) positioning the cover of said transport contain on said main body to enclose said first and second drums and said first and second neutron absorber plates in said transport container.
