Ne is not only a clean source of energy, it is also the cheapest.

So, cold water needs to be cycled through to prevent the modulating water from boiling away. So, due to the malfunctioning valve, the cold water (cid:449)as(cid:374)(cid:859)t flo(cid:449)i(cid:374)g i(cid:374)to the (cid:396)ea(cid:272)to(cid:396) (cid:272)o(cid:396)e (cid:272)ausi(cid:374)g the (cid:373)ode(cid:396)ato(cid:396) (cid:449)ate(cid:396) to heat up to hotte(cid:396) than usual. As soon as this was caught, extra control rods were plunged in the reactor core where the fuel is.
