Title: Burnup degree credit introduction for spent fuel assembly
Inventor: KITANO TERUAKI
IPC: G21C17/06
Filed: 1992-08-12
Abstract: PURPOSE:To make a critical safety plan in consideration of burnup degree of a nuclear fuel storage fecility by finding effective neutron multiplication constant in a storage system by correlation between the effective neutron multiplication constant and equivalent initial enrichment established by new fuel. CONSTITUTION:Correlation of equivalent enrichment of each new fuel of a single system and a plural system and effective neutron multiplication constant (hereinafter abbreviated as multiplication constant) is found. Multiplication constant Ko of the single system of a used fuel assembly 1 is measured, and equivalent initial enrichment eo is acquired. Additionally, multiplication constant Kc against the equivalent initial enrichment eo of the plural system is acquired. By using corelation of burnup in the single system and multiplication constant Keff, burnup bo is acquired from the multiplication constant Ko and the equivalent initial enrichment eo of a parameter. In the same way, multiplication constant Kb of the plural system requiring critical safety estimation is finally acquired from the burnup bo and initial enrichment of the parameter. It is confirmed that the multiplication constant Kb is smaller than the multiplication constant Kc found by equivalent initial enrichment conversion. Consequently, it is possible to make multiplication constant estimation value of the plural system requiring safety estimation as Kc.

Title: Rotary retort furnace
Inventor: AKAMI SHOICHI
IPC: F27B5/00
Filed: 1987-08-31
Abstract: PURPOSE: To achieve a simplification of the structure and a facilitation of the assembling by a method wherein a protrusion is formed on one end face of a shaft tube and a recess part on the other end face to get the protrusion fitted thereinto while adjacent blade pieces are so arranged to let them link to each other for preventing the breakage of a beater member. CONSTITUTION: With the rotation of a core tube 3, a beater member 9 rotates. In this process, even if a resistance differently acts on each of beater unit bodies 10, the beater unit bodies rotate together as the adjacent blade pieces 12 are interlinked by a link member 32. Therefore, a torsion moment and a shearing stress reduce working on a protrusion 13 fitted into a recess part 14 formed in the shaft tube 11 to make the beater unit bodies 10 hard to break. As the link means 32 is so arranged to get the blade pieces 12 welded together with half sides of two grasping plates 33 protruding at one end thereof, the structure is simple and the assembling and the removal of each beater unit body 10 is easy. The number of the protrusions 13 formed in the shaft tube 11 may be two or more, not limited to one and the shape thereof may be a square shaft.  In this case, the recess part 14 is also formed corresponding to the number and the shape of the protrusion 13.
