pairs, " Eskom said. The unit, a CP1 model
built by Framatome in 1984, had been
slated to begin a maintenance and refueling
outage in February. In September,
Eskom received the first of six replacement
steam generators for the Koeberg
units as part of a $1.2 billion program to
extend the plant's operating life by 20
years. The generators were designed by
Orano and are being manufactured under
a subcontract by Shanghai Electric
Power Equipment Co. The first three
steam generators were scheduled to
be installed at Unit 1 between February
and June this year, and between January
2022 and May 2022 for Unit 2. As
Eskom announced yet another round of
load shedding in January, Unit 1's early
outage adds to 13.2 GW of capacity of
unplanned outages and another 6.4 GW
that is out for planned maintenance. The
utility also said a second wave of COVID-19
cases is affecting its operations.
Ringhals 1 Permanently Closed.
Ringhals 1, a 1976-commissioned 881MW
boiling water reactor (BWR) owned
jointly by Vattenfall and E.ON at the
four-unit plant in Sweden's Väröhalvön
peninsula area, powered down permanently
on Dec. 31, making it the fourth
reactor to close in Sweden in the last
seven years. The closure follows Ringhals
2, a Westinghouse pressurized water
reactor (PWR) that Vattenfall shut
down in December 2019. The company,
however plans to continue operating
Ringhals 3 and 4, also both Westinghouse
PWRs, for at least 60 years, until
the beginning of the 2040s. Vattenfall
built Ringhals 1 as a BWR and Ringhals
2 as a PWR because, though the company
owned 100% by Sweden set out
to model Ringhals on U.S.-based Westinghouse's
design in the late 1960s,
the state sought to merge its nuclear
entity, AB Atomenergi with Swedish
industrial company ASEA's nuclear department.
" In order to make Asea accept
the merger, the state offered to
bulid an Asea reactor in Ringhals. This
is why Ringhals started with two reactors
Ringhals 1 (Asea-Atom) and Ringhals
2 (Westinghouse), " Vattenfall said.
However, Asea-Atom's reactor was delayed,
which is why Ringhals 2 was put
into operation first. " The final cost was
almost twice as much as estimated.
Despite this, Ringhals proved to be a
highly profitable investment, " it said.

agreement with UK firm Rolls-Royce
to acquire its civil nuclear instrumentation
and control (I&C) business, which
operates mainly in France and China.
If it garners the required regulatory
approvals, the transaction, expected
to close in the second half of 2021,
will allow Framatome to absorb RollsRoyce's
products and technologies in
I&C systems, which are installed in
150 operating nuclear reactors worldwide.
Rolls-Royce has designed, manufactured,
installed, and renovated
analog and digital safety I&C systems
for nuclear reactors all over the world.
It was the original equipment supplier
of process controls and safety I&C
systems of France's 58 reactors, and it
designed and installed the first digital
protection system in the world at the
Paluel nuclear plant in France in 1984.
According to Rolls-Royce CEO Warren
East, the transaction will mark a
simplification of the technology company's
portfolio, and it will contribute
toward an August 2020-announced
target to generate more than £2 billion
from business division disposals.
In 2019, Rolls-Royce's I&C business
had 550 employees and reported revenues
of $113.5 million, which were
consolidated within results reported
by its Power Systems business. In an
investor update on Dec. 11, company
executives said the Power Systems
business " experienced a significant fall
in demand in most non-governmental
end markets " over 2020. Other assets
the company is considering divesting
include its ITP Aero aeronautical and
industrial engine business, and its
medium-speed gas and diesel engines
business, Bergen Engines.
1.2-GW Turkish Hydropower Project
on Tigris Fully Operational.
The 1.2-GW Ilisu Dam & Hydroelectric
Power Plant on the Tigris river in
southeastern Turkey's Madrin District
was declared fully operational on Dec.
24. Approved in 1997, the $2.4 billion
state-owned project suffered several
setbacks and delays during its 11-year
construction period, but as officials
have noted, it required considerable
planning, including to resettle local residents
and protect historic and cultural
assets. The area was home to a Byzantine
fortress and the 12,000-year-old
town of Hasankeyf, which has thousands
of neolithic caves and hundreds
