Once-through THWRs produce lower amounts of transuranics but not significantly lower radiotoxicities of the actinides than the natural uranium fueled HWR, although the radiotoxicity for the first 40,000 years is much lower for the THWRs with uranium topping.
The plutonium topped HWR systems will reduce plutonium at a much higher rate than with PWR-MOX systems. The radiotoxicity of the final waste form, however, is much higher than for the natural uranium fueled HWR.
