Contracts
CRDMs
Curtiss-Wright Corporation
an-
nounced that its Flow Control segment’s
Electro-Mechanical Division (EMD)
business unit has signed a contract with
NuScale Power to design control rod
drive mechanisms (CRDMs) for NuS-
cale’s small modular reactor (SMR).
Curtiss-Wright will design the CRDMs,
which control the insertion and removal
of control rod assemblies, at its facility in
Mt. Pleasant, Pa. The initial contract cov-
ers the design phase of the program.
Curtiss-Wright is a designer and
manufacturer of CRDMs, having supplied
over 5,000 units worldwide for nuclear
power plants, including the first-ever
installation on a reactor head in the U.S.
NuScale is pursuing U.S. Nuclear
Regulatory Commission (NRC) approval
for its SMR design, which is an integral
pressurized-water reactor (iPWR). The
design is a natural circulation light
water reactor with the reactor core and
helical coil steam generator located in a
common reactor vessel in a cylindrical
steel containment. The reactor vessel/
containment module is submerged in
water in the reactor building safety
related pool. The reactor building, which
is located below grade, is designed to
hold 12 SMRs. Each NuScale SMR has
a rated thermal output of 160 MWt and
electrical output of 45 MWe, yielding a
total capacity of 540 MWe for 12 SMRs.

Instrumentation &
Control
Rolls-Royce
has been awarded a
contract by China Guangdong Nuclear
Power Corporation (CGNPC) to supply its
Spinline
TM
digital safety instrumentation
and control (I&C) technology for the
modernization program of the Ling Ao
nuclear power plant.
The contract covers the modern-
ization of the Neutron Instrumentation
Systems for reactor units 1 and 2 of the
Ling Ao Power Plant. The original ana-
logue platforms will be replaced with the
latest digital safety technology that was
installed in the plant’s newer phase II re-
actor units 3 and 4.
The
Neutron
Instrumentation
System is a safety-critical I&C system
that ensures the integrity of the nuclear
reactor. Compliant with international
nuclear safety I&C requirements, it uses
Rolls-Royce Spinline
TM
technology to
enable utilities to optimize the safety,
availability and maintenance of nuclear
power plants.

Reactor Coolant Pumps
ClydeUnion Pumps, an
SPX
Brand,
was awarded a design engineering
contract from Babcock & Wilcox
mPower for the Reactor Coolant Pumps
(RCP’s) on their Generation mPower
TM
Small Modular Reactor (SMR). The
contract is for an external canned motor
pump design for the RCPs to support the
mPower
TM
reactor. The pumps are ASME
Class 1 with the detail design and proven
technology coming from the ClydeUnion
Pumps facility in Annecy, France.
The reactor design is a scalable,
modular, Advanced Light Water Reactor
(ALWR) system in which the nuclear
core and steam generators are contained
within a single vessel. The Generation
mPower
TM
electric generation plant has
the capacity to match customer demand in
nominal 180 MWe increments for a four-
year operating cycle without refueling,
using standard pressurized water reactor
(PWR) fuel.

Heat Exchanger
Treatment
Studsvik
has signed a contract with
LLW Repository Ltd (LLWR) for the
transport and treatment of the remaining
10 redundant heat exchangers from the
MagnoxBerkeleySite, inGloucestershire,
England. The total contract value is
approximately £15M ($23M).
The heat exchangers (boilers) each
weigh over 300 tonnes andwere used as an
integral part of the electricity production
process of the nuclear power station
before it ceased operation in 1989. There
were 15 heat exchangers remaining at the
site of which the first 5 were successfully
removed in March 2012. These are now
being treated by Studsvik. This contract
is for the transport and treatment of
the remaining 10 heat exchangers, and
will complete an important step in the
decommissioning program at Berkeley
Site.
LLWR is acting on behalf of Magnox
Ltd for the procurement and contract
management of the project, which is
scheduled to take place in 2013.
Early in 2013 Studsvik will transport
the heat exchangers by road and sea to its
processing facility at the Studsvik site,
close to Nyköping in Sweden. Treatment
of the first heat exchanger will start in
2013 with the last heat exchanger planned
for treatment during 2014.

Safety Systems
Westinghouse Electric Company
has received two contracts from
Nuklearna Elektrarna Krško (NEK)
to provide a passive containment dry-
filter method (DFM) venting system
and a passive autocatalytic recombiner
hydrogen-control system at the Krško
Nuclear Power Plant in Slovenia. The
two systems enhance safety in the area of
severe accident management.
Designed to provide additional mea-
sures for ensuring containment integrity,
the two systems are part of the range of
products and services Westinghouse of-
fers to the global fleet of nuclear power
plants that further enhance plant safety
and help to mitigate events like that which
occurred at Japan’s Fukushima Daiichi
Nuclear Power Plant from occurring. The
engineering, design, supply and installa-
tion of the two passive safety systems, in-
cluding aerosol and iodine filter units, is
scheduled to be complete by April 2015.
The Westinghouse passive autocata-
lytic recombiner solution helps to control
and mitigate the effects of hydrogen gen-
eration under severe accident conditions
and includes completely passive equip-
ment, little-to-zero maintenance costs,
easy installation, and robustness with
respect to atmospheric conditions or seis-
mic loads.
