Cold-state physical characteristics of ÉGP-6 reactors after upgrading
- 26 Downloads
Measurements and calculations important to safety are reported for ÉGP-6 reactors in the cold state. These data give the sufficient number of manual control rods to be fitted with upgraded RS-AZ drives, and it is shown that the reactor subcriticality can be determined. Measurements have been made on the temperature coefficients of reactivity, the reactivity change when the coolant is lost from the new cooling channels for the control rods, and the reactivity increment caused by using these new channels.
