Re: [cdn-nucl-l] NRU restarted
Well done indeed. It shows just what the engineers,
scientists and management from AECL and associated companies CAN DO, and
HAVE DONE many times in the past, with focus, resources and a sense of
quality (which includes safety culture, sane project management and a
host of other attributes of professionalism in my book). But
it is a product, not a sum. Screw one thing up and you can lose the
game.
Off topic but related to NRU: Hope someone puts a megaphone to Harper's
ear and sings a song of praise! I don't know of any successful
nuclear enterprise anywhere in the world that does not have solid
government backing. Not to say that AECL has been blameless but the
federal and provincial waffling over the years has been a major
contributor to our current nuclear woes, IMHO. The Feds and Ontario
need to come to grips with the hard reality that wind, solar and
conservation will not provide what we need for a solid industrial base
which, despite its negatives, is needed for sustaining our quality of
life.

UNRESTRICTED | ILLIMITÉ
As announced on the AECL web site
http://www.aecl.ca/, NRU is back in operation at full power,
for
producing
medical radioisotopes and neutrons for the
National Research Council neutron scattering facility.
NRU was tested at low power over the past
weekend.
An enormous amount of effort was expended by
the dedicated
restart team, to determine the cause of the
leak (external corrosion on the calandria vessel),
develop techniques to
repair it (requiring tool development) with
weld overlay (thanks to the additional
welding expertise of
Liburdi Engineering of Dundas, Ontario), make
modifications to some systems to reduce the corrosion rate in the
“J-rod” annulus,
reassemble the core internals
(instrumentation, control, fuel), and recommission many systems (many of
which were also refurbished/repaired/upgraded).
My hat’s off to the restart team - a job well
done!
cheers
