Calculating the Neutron Radiation in the Spent Nuclear Fuel of VVER-1200 Reactors

Results are presented from calculating the neutron radiation of spent nuclear fuel (SNF) from stationary campaigns of VVER-1000 and VVER-1200 reactors due to spontaneous fission and (α, n ) reactions. An analytical dependence is obtained for the average number of neutrons produced in spent nuclear f...

Zusammenfassung:Results are presented from calculating the neutron radiation of spent nuclear fuel (SNF) from stationary campaigns of VVER-1000 and VVER-1200 reactors due to spontaneous fission and (α, n ) reactions. An analytical dependence is obtained for the average number of neutrons produced in spent nuclear fuel per α-particle on the particle’s energy. The neutron radiation of VVER-1200 spent nuclear fuel is several times higher than that of a VVER-1000 reactor, due primarily to the increased number of 244 Cm isotopes produced in high-burnup fuel.
