High transmutation rates of C and Si to form H, He, Mg, and Al continue to be a concern.
In certain radiation environments, such as the spallation neutron source (SNS) presently in design and construction, the high transmutation production rate for helium and hydrogen, concomitant with displacement damage, may affect the mechanical properties of structural materials.
TRU transmutation rate is 282 kg/yr.
The in-core transmutation constants, such as transmutation rate and nuclides inventories can be computed and evaluated by the code.
The 51V transmutation rate is proportional to and dominated by the thermal neutron fluence (E<0.414 eV).
The transmutation rate of minor actinides is approximately 250 kg/y at 80% load factor.
The total transmutation rate of MA is 328.8 kg per effective full power year.
A preliminary neutronics calculation based on ST transmutation blanket shows that the proposed system has a high transmutation capability for MA wastes.
The converter was optimized to maximize transmutation rate of 129I via two channels: 129I γ,n)128I and 129I(n,γ 130I.
