Event Report: Minnesota nuke leaked condensate containing tritium following pump failure

Yesterday afternoon, a condensate return pump failed at the Prairie Island nuclear power plant in Minnesota, releasing 27 gallons water. Prairie Island released an unusually detailed report of what the water contained:

“The release contained the following chemicals:

1) 11.2 ppm of methoxy propylamine (MPA);
2) 8.1ppm of ammonia;
3) 11.2 ppb of hydrazine;
4) 1.50 E-5 microCi/mL (15,000 pCi/L) of tritium.”

Prairie Island has installed a catch basin to prevent more water from flowing onto the ground, and has closed the steam inlet valve.

Both of Prairie Island’s reactors continued to operate at 100 per cent output following the incident.
