[ RadSafe ] Chinese fast reactor starts supplying electricity 21July 11

Wed Jul 27 12:57:14 CDT 2011

Holes were drilled through the reactor vessel to make sure that no one
could later decide to restart the reactor.

The Hanford sodium cooled reactor is the Fast Flux Test Facility (FFTF).
The sodium has been removed and the building is waiting for DOE to fund
demolition.

I was a MARFette, the rodless wonder, back in 83/84.

Don't we still have the sodium reactor at Hanford?  I know it's been
shut down forever, but did they disassemble the unit?

I was a student and a staff ELT instructor at the D1G NPTU prototype in
Ballston Spa, NY back in the 1980's. The first core in this prototype
was a sodium cooled reactor core. Perhaps there is someone out there who
remembers working at that facility.

Yes - all that sodium submerged in the huge water environment doesn't 
seem to make much sense - at least on first blush.

I encountered the SeaWolf as a shipyard RadCon HP and got to see them 
cut her in half and add a 30 ft section.  An interesting experience of 
seeing brute force applied with finesse.  Or course she was a PWR by 
then - distinguished from the new plants in that you could traverse the 
length of the ship by walking through a section above the reactor 
compartment - between the CRDM's - called I am told - "Sherwood Forest".
