T
HE OFFICIAL REASON FOR THE
accident that killed 75 people at
RusHydro’s Sayano-Shushenskaya
hydro power plant in Siberia is still
unknown as IWP&DC goes to press,
as Russian state accident investigators
delayed releasing their findings into the
partial destruction until late September.
However, state-owned media
reported that the first generating
unit at the 6.4GW plant could well be
operational again in the first quarter
of 2010. It is also understood that
the rebuild could take up to five years,
where RusHydro previously said the
work might take up to three years.
Three of the plants 10 units were
destroyed during the fatal accident at
the plant on 17 August, while six suf-
fered varying degrees of damage and
one flood damage only.
Initial findings into the disaster
were to have been released in early
September, then mid-month, but have
now been re-scheduled again.
The state accident investigators have
postponed the release of their findings
following a meeting with government
ministers, who want to also establish a
parliamentary investigation committee.
The agency said that ministers believed
recommendations for future operations
should have ongoing involvement of
equipment manufacturers.
While talks are underway to get
loans to support the plant rebuild, it is
understood that the utility also plans to
issue shares to help raise funds. The
government still holds a stake in the
utility, and is also hearing an applica-
tion from the Ministry of Energy for part
of next year’s budget to be earmarked
to support the rebuild.
RusHydro has been planning
to replace six units, possibly with
turbine-generators of larger capacity
than the original 640MW, and partial
rebuild of four units.
The plant was fitted out over 1978-
85, and is located on the Yenisei river
at the foot of a 242m high concrete
gravity arch dam.
As we went to press, RusHydro
announced that more than 400
people from the village of nearby
village of Cheryomushki and the
Sayano-Shushenskaya project have
received psychological assistance at
it’s Psychological Support Center, as
a result of the accident.
The company said 367 adults and
82 children have visited the centre,
which was established by JSC RusHydro
with the goal of normalizing the socio-
psychological climate in the village
of Cheryomushki. The Center has a
staff of 25 specialists from Abakan,
Sayanogorsk and Cheryomushki.
All search and rescue work at the
Sayano-Shushenskaya project has
now been completed, and active res-
toration work has started.

US DoE awards funding for hydro tech projects
A
TOTAL OF UP TO US$14.6M OF
funding has been awarded by
the US Department of Energy
(DoE) to help fund commercialisation
of hydro power technologies, espe-
cially marine and hydrokinetic.
There are 22 proposed awards
being negotiated, and the funding
ranges in size from US$500,00 to
US$1.5M, the majority being at the
lower end. The selected projects suc-
cessfully address five topic areas:

Niagara build pushes ahead despite rock fall
P
LANNED MAINTENANCE WORK
has been brought forward
for tunnelling equipment on
Ontario Power Generation’s (OPG)
Niagara Tunnel project while a small
rock fall at the temporary lining is
investigated and repaired.
Select work resumed quickly after
the incident, which happened more
than 3km along the tunnel but well
behind the tunnel boring machine, “Big
Becky”. Both rock and the lining fell in
the accident but no-one was injured.
The TBM has excavated more than
half of the 10.2km long tunnel, which
is a key part of a scheme to expand
production at the Sir Adam Beck
Complex. The utility plans to add
1600GWh of output per year.
The incident happened in a stretch
of tunnel than previously suffered over-
break problems. The difficulties with the
Queenston shale led to the remainder
of the dig having to be realigned and a
major contract renegotiation between
OPG and contractor Strabag.
Strabag has brought forward a six-
week planned maintenance outage for
excavation equipment, due for the end
of the month, to minimise programme
impacts.
While repairs to the temporary
lining proceed and work continues to
install the permanent lining, OPG said
no impact on project cost and sched-
ule was expected.
At the half year, 30 June, almost
4570m of the tunnel, or 45%, had
been excavated by the TBM. The client
noted in its H1-’09 report that realign-
ment of the tunnel had enabled the
machine to improve progress, reduc-
ing rock overbreak to minimise exca-
vation in the Queenston shale.
By then, tunnel lining was ahead
of the revised schedule, which was
negotiated along with the cost by
OPG and the contractor, Strabag. Due
to the poor ground and tunnelling dif-
ficulties, the project completion was
re-negotiated from mid-2010 to the
end of 2013.
