1500 cubic meters

Did you really pick the figure from the RBMK reactor type?

For PWRs, 250 m³ of LILW per GW annum is 28.5 m³ of LILW per TWh.

2.5 million turkeys in a 2.4 kW oven for 3.5 hours uses 0.021 TWh.

So 2.5 million turkeys and 0.6 m³ total low and intermediate wastes generated. Most of this can be released after ~300 years with negligible activity over natural background. That is a long time but not “basically forever”.
