Germany:
The unused mixed-oxide (MOX) fuel fabrication facility at
Hanau will be decommissioned, Siemens Power Generation confirmed,
November 2001. The company had planned to export equipment
from the plant for use in a new MOX plant in Russia, but has
decided the project is 'no longer feasible' in the 'current
political situation'.
In June
2001, RWE Power filed an application to dismantle the Mulheim-Karlich
nuclear power plant, in light of Germany's gradual phase-out
programme. Dismantling is planned to commence 2003 with the
project excpected to take about 10 years.
5.2
Japan: Plans to dismantle Tokai-1 - the country's first
commercial nuclear power reactor - were submitted by Japan
Atomic Power Co (JAPC) with the Ministry of Economy, Trade
and Industry (METI) in October 2001. JAPC estimates the decommissioning
project will last about 17 years, starting this fiscal year.
The proposed plan includes 10 years of preparatory work and
removal of auxiliary facilities, followed by the start of
full-scale dismantling and removal of the 159 MWe, gas-cooled
reactor (GCR) in 2011. The 3-phase project is summarised as
follows:
- Phase
1 (2001-2005): Preparatory work, draining of the spent fuel
cooling pools and removal of turbines. This commenced in
December 2001
- Phase
2 (2006-2010): Removal of auxiliary facilities such as heat
exchangers.
- Phase
3 (2011-2017): Dismantling and removal of the reactor building
and core.
JAPC plans
to develop a suitable disposal site to take the waste produced
prior to the commencement of phase 3 decommissioning. The
project is expected to cost a total 93 billion yen (some US$7.6
million).
5.3
Kazakhstan: December 2001, the DOE reported on progress
made to provide for the safe shutdown of BN-350 Aktau. Successful
achievements include the installation of extensive fire-safety
equipment, design and fabrication of "cesium traps"
to decontaminate the reactor's radioactive sodium coolant
and the commencement of procedures for sodium coolant draining
and processing. The spent fuel was removed and placed in wet
storage during summer 2001.
5.4
US: July 2001, British Nuclear Fuels Inc. asked the US
Nuclear Regulatory Commission (NRC) to license the Big Rock
Point reactor vessel as a type B transport package under 10
CFR Part 71. The certification would allow a one-time shipment
of the reactor vessel to the Barnwell low-level waste disposal
facility operated by Chem-Nuclear Systems.
The NRC
announced in October 2001 that it was seeking public opinion
on entombment as a decommissioning option for nuclear power
plants. Currently NRC regulations require that a facility
be decommissioned within 60 years after operations have finished
at the plant. The Entombment option would allow for facilities
to be maintained in a specially engineered structure beyond
60 years to enable the decay of radioactivity to a level that
permits release of the site for unrestricted use. Entombment
can offer reduced worker exposure to radioactivity and reduced
transportation of radioactively contaminated material from
the plant to a disposal site.
5.5
Ukraine: In June 2001, a new, modern, state-of-the-art
replacement heat plant was officially opened at the Chernobyl
industrial site. The heat plant will provide energy for the
site and other pre-decommissioning facilities.
In October 2001 the International
Chernobyl Centre highlighted the progress being made on
two decommissioning projects. The liquid radwaste treatment
plant (LRTP) is currently under construction (a turn-key contract
for the project was signed between ChNPP and a consortium
led by Belgatom in August 1999). Completion of the project
is expected by mid-2003. The interim spent fuel storage facility
(ISF-2) is scheduled for completion late 2003. A draft governmental
decree approving the spent fuel storage facility project to
store spent nuclear fuel at the Chernobyl nuclear power plant
site was approved by the government's committee on industrial
policy and the fuel and energy complex in July 2001. This
facility will have the capacity to store about 22,000 RBMK
fuel assemblies and 3000 absorber rods from units 1-3 for
up to 100 years. (ChNPP and a consortium led by Framatome
signed a contract for the construction of ISF-2 in June 1999)
