[1F05] Seismic Evaluation of Control Rod for JRR-3

*Masanobu Kikuchi1, Sho Kawamura1, Masaaki Araki1 (1. JAEA)

Keywords:JRR-3, New regulatory standard, Seismic Evaluation

We carried out seismic evaluation and showed suitability in the new regulatory standard of JRR-3. CRDM and insertion property of control rod carried out more detailed approach because the past results had gotten the serious results of seismic safety margin. As a result, it was confirmed that CRDM and insertion property of control rod have sufficient seismic safety margin.
