Measuring control rod worth
Web2-3 Compensating CRs are three CRs located at 60° and 180° position from one of the measuring CRs, i.e., the three rods inserted upper than measuring CRs. 2-4 Compensating CRs are the same as in the case 2-3, but the reactivity measurement for three measuring CRs is carried out in succession. 3 Measuring CRs are six of R1, i.e. all R1 rods. WebControl rod worth can be measured in some methods that are the following methods: ・ Boron swap; ・ Rod swap; ・ Subcritical rod worth. There are two ways definite control rod worth that is integral rod worth and differential rod worth.
