Application of a Fuel-Element Energy Release Restoration Module in the ATHLET/BIPR-VVER Complex in Modeling a Control-Rod Ejection Accident in VVER-1000

The results of modeling VVER-1000 fuel elements, performed using a fuel-element energy release restoration module integrated into the ATHLET/BIPR-VVER software system, are presented. The results are presented for the example of the calculation of a reactivity accident with the ejection of a control rod from the reactor core.
