Comparison of WG-MOX and UOX decay heat from 0 to 10,000 days after discharge for BWR fuel. The decay heat during from 500 to 3000 days is plotted for WG-MOX and UOX in Fig. A6. Figure A6 shows that WG-MOX and UOX have similar decay heat during the time that the fuel would be held in a spent fuel pool.
