Title: Tatsuya Iwamoto and Nuclear Reactor Fueling Plan Evaluation.

Introduction

Tatsuya Iwamoto is an inventor associated with Global Nuclear Fuel-Japan Co., Ltd. His patent work concerns evaluating nuclear reactor fueling plans and calculating reactor shutdown margins. The supplied information identifies him as based in Kanagawa, Japan, and credits him with 1 patent.

Latest Patents

Iwamoto’s listed patent is “System and Method for Evaluating Nuclear Reactor Fueling Plan.” The invention is designed to evaluate reactor shutdown margins quickly and accurately during the formulation of a fueling plan.

The system includes a fueling procedure formulating part and an input setting part with databases. It first uses a relatively simple physics model to calculate control rod worth for each fueling step, comparing the reactor core’s subcriticality with all control rods inserted against its subcriticality when one control rod is withdrawn. It then selects a set number of the control rod candidates with the greatest worth. A more detailed physics model is used to calculate the reactor shutdown margin for each selected candidate.

Career Highlights

The patent reflects work on improving the speed and accuracy of nuclear reactor fueling-plan evaluation. Its staged approach uses a simpler model to identify promising control rod candidates before applying a more detailed model to calculate shutdown margins.

Collaborations

The supplied information names Teppei Yamana and Hitoshi Sato as Iwamoto’s coworkers. It does not specify their roles in the patent or describe particular collaborations.

Conclusion

Tatsuya Iwamoto’s listed invention addresses an important technical task in nuclear reactor operations by combining candidate selection with detailed shutdown-margin calculations.
