Title: Method for adjusting and confirming o/m ratio of mox fuel
Inventor: KATO MASATO
IPC: G21C3/62
Filed: 2000-08-25
Abstract: PROBLEM TO BE SOLVED: To provide a method allowing an arbitrary and easy adjustment of an O/M ratio important for handling MOX fuel and provide a method allowing accurate confirmation of the O/M ratio for the MOX fuel itself loaded into a nuclear reactor. SOLUTION: The O/M ratio of MOX fuel sintered pellet can be adjusted to an arbitrary value corresponding to a heat treatment temperature by performing the heat treating for the sintered pellet at a prescribed temperature within a range of 800 to 2000 deg.C in reducing gas and stopping the heat treatment after oxygen partial pressure of off-gas during the heat processing becomes constant. By performing a first heat treatment for adjusting the O/M ratio of the MOX fuel sintered pellet to 2.00 before the above heat treatment and performing the heat treatment (second heat treatment), the pellet of the arbitrary O/M ratio can be obtained. A difference of pellet weight after the first heat treatment and pellet weight after the second heat treatment is regarded as a change of oxygen weight and the O/M ratio of the pellet itself after the second heat treatment can be directly confirmed.

Title: Real time scheduling method for automatic control overhead crane and operation control apparatus for plural overhead cranes
Inventor: KURISU TSUTOMU
IPC: B66C15/04
Filed: 2000-08-25
Abstract: PROBLEM TO BE SOLVED: To prevent collision of automatic control overhead cranes existing on the same lane and to improve the rate of operation. SOLUTION: Before the original planned conveying schedule is instructed to the overhead crane, previous simulation is performed to verify whether it interferes with some other overhead crane or not. In the case of interference, simulation is again performed according to the conveying schedule having the same priority as that of the original planned conveying schedule to verify whether it interferes with some other overhead crane or not. In the case of causing interference in any conveying schedule with the same priority, within the necessary minimum range, retreat and standby schedule is created and instructed, and then the original conveying schedule is instructed.  After the start of operating the crane, the operating condition of the crane is monitored to monitor difference between simulation and the actual operation, and when the difference exceeds a fixed value, a standby command is output to correct the difference and prevent a collision, and the next simulation accuracy is heightened by coincidence between the simulation and the actual operation to improve the rate of operation.
