What actions has KHNP carried out in response to the
Fukushima accident and what can be done at existing nuclear plants
to ensure their safety in response to learning from
Fukushima?
Right after the Fukushima accident, KHNP carried out self-safety
reviews of all 21 units in operation and received a special safety
review by a government-organized team of experts outside the
company. The results of the reviews showed that Korean nuclear
power plants were safe from natural disasters such as earthquakes
and tsunamis.
Also, the IAEA's IRRS (Integrated Regulatory Review Service) on
Korean regulatory bodies found that Korea's response to the
Fukushima accident was timely and effective, and that Korean
nuclear power plants maintained the best possible safety.
Nevertheless, KHNP has established 56 short and long-term
improvement plans to enhance the safety of nuclear power plants
currently in operation against serious natural disasters. These
plans are being broadly implemented not only in the operating
plants but also in the plants under construction and will be
completed by 2015.
Has your company been involved in the recovery operations
at Fukushima?
After a month from the Fukushima accident, I visited TEPCO and met
its executive members and key figures of the Japanese nuclear
industry. We discussed measures to help restoration work of the
Fukushima nuclear power plant site. KHNP gave full support both in
material and technical ways by sending protective face masks,
filters and boric acid. As technical assistance, we dispatched 2
experts on severe accident and disaster measure to WANO Tokyo
Center to follow up the progress of the accident and to actively
support restoration work on the spot.
In light of the lessons learned from the Fukushima
accident, what does the world nuclear industry as a whole need to
do?
A nuclear power plant accident is not a problem of the sole country
where the accident happens but a common issue that neighboring
countries and the entire international community should work
together to cope with. What's most important is the transparent
disclosure and sharing of information when an accident occurs. It
is relieving to see that an international cooperation system for
nuclear safety is being reinforced in light of the lessons learned
from the Fukushima accident.
Has Fukushima changed your opinion of nuclear power and
what do you see as the future for nuclear power?
The global demand for energy is continuously on the rise and
greenhouse gases generated from burning fossil fuels is still
troubling the earth. Alternative energy should be
environment-friendly; ensuring a sustainable supply of low-cost and
high-efficiency energy. Thus, I think nuclear energy is still the
most viable alternative.
It is true that the nuclear industry is having difficulties in
expanding its business after the Fukushima accident. A nuclear
power plant is truly a concentration of advanced technologies and
the key point is how safely we take advantage of it. Technologies
have been developed in a way that nuclear energy has become much
safer and improvements will be continuously made as we keep doing
our best for the further advancement of nuclear technologies.
If we enhance safety to the level that nuclear power plants are
safe even against the worst possible natural disasters, nuclear
power will be able to serve as a useful tool to contribute to
economic development and prosperity of our lives.
What features do new reactor designs offer to address the
issues faced at Fukushima?
The Advanced Power Reactor 1400(APR 1400) is an evolutionary
pressurized water reactor with an electric output of 1,400MW
developed in Korea based on 40 years operation experiences and
technology advancements. APR1400 is under construction in Korea and
UAE. Advanced design features, such as direct vessel injection,
passive fluidic device, Passive Auto-catalytic Recombiners(PARs)
and Emergency Containment Spray Backup System(ECSBS) are adopted in
APR1400 in order to enhance safety. Among them, passive fluidic
device and PARs are passive safety devices operable without
electricity.
In order to make inroads into the various nuclear power plant
markets like Europe, KHNP has made design improvements against
air-craft crash and earthquakes to fundamentally prevent any
possibility of serious accidents like the Fukushima accident. The
newly upgraded reactor is designed with Passive Auxiliary Feedwater
System(PAFS) which can provide cooling water through natural
circulation without any external power source when an extremely
severe accident takes place and all power sources are
lost.
