It's a sure thing.

Coal and Heavy oil fill the oceans with heavy metals like mercury and
release large amounts of radioactiviy. Mercury poisoning is causing
stillbirths and birth defects right now.

Nuclear reactors do no such thing. For the same amounte of energy
nuclear power releases a negligable miniscule fraction as much
radioactiviy and essentialy no heavy metals.

The HTGR or molten metal reactors do not expose the water they are
thermochenicaly spliting to the nuclear core. In the HTGR the heat
is carried away by Helium gas running in tubes through the reactor and
then the chemicals are heated by the gas through metal walls in a heat
exchanger well away from the reactor. The fuel in a HTGR consists of
a sand sized grain core of uranium oxide that is then sourounded by
six layers of silicon carbide and graphite and then assembled into
golf balls. The fuel is secure in the grains themselves even if a
pellet were smashed open.
