They keep trying to make this Chernobyl revisited.  Does the former
Chair of the NRC really have any actual knowledge or is he just
politician?  This is beginning to look like more of the Gundersen or
Michio Kaku doomsday scenario approach.  It would seem like you could
filter out the radioactive elements from the cooling water and
concentrate them; is that feasible or would the result be too hot to

Japan Expert: Cancel plans for trying to remove Fukushima melted fuel
— Cover buildings with concrete instead(VIDEO)

Tetsuro Tsutsui, Member of Nuclear Regulation Subcommittee, Citizens’
Commission on Nuclear Energy (CCNE) Nuclear Power Plant Technical
Experts’ Group:

Plans for removal of debris should be cancelled. The current METI and
Tepco road map says that the removal of the [melted fuel] debris will
begin 8.5 years after the accident and be completed 20 to 25 years
after the accident.

We propose the following alternative: The contaminated water problem
should be resolved. Spent fuel in the spent fuel pools should be
removed as planned. Then we propose that the water cooling of the
damaged reactor cores should be continued until the decay heat is
reduced sufficiently for natural air circulation. Subsequently, the
equipment and building areas [slated?] for isolation should be covered
with concrete.

Gregory Jaczko: The Ongoing Fukushima Daiichi Crisis 9/24/2013

This proposed method could avoid many uncertain difficulties which
would arise in the METI/Tepco plan, including: Plugging an uncertain
number of cracks in the pressure and containment vessels; The need to
develop missiles to break up the blocks of debris and remove the
pieces of debris; The extensive radioactive dose to workers; The huge
financial expenses.
