throughout the project. These reports are subject to
approval by the commission.
The CNSC has already agreed there would be no
significant adverse environmental effects, given
available mitigation actions, as a result of the
refurbishment and continued operation of the
reactors.
Darlington’s Integrated Safety Review confirmed the
plant met modern codes and standards, and that it
has been using industry best practices.
A Global Assessment Report, which is an overall risk
judgment on the acceptability of continued plant
operations, deemed the plant safe and reliable.
Two independent oversight organizations have also
been established for the project. One reports to the
10
project executive and the OPG board of directors,
and the other reports to the Ontario Ministry of
Energy, Northern Development and Mines.
The team behind the refurbishment is comprised
of OPG’s partners, industry experts, energy
professionals, and tradespeople. Participating
organizations include power generation technology
builder GE Power; builder and fabricator ES Fox
Construction; contractor Black & McDonald; fuel
and fuel bundle provider BWTX Canada; and
CanAtom Power Group, which is focused on the
refurbishment’s retube and feeder replacement
program.
During the refurbishment, each reactor will be taken
out of service for about three years so the team can
replace fuel channels, feeder pipes, calandria tubes
and end fittings; rehabilitate steam generators,
