FEPC Chairman Tsunehisa Katsumata, April 18, 2008:
Today, I would like to comment on two topics. The first is the joint meeting of APP task forces; the second is the interim reports on the seismic back-check project.
1. Joint Meeting of APP Task Forces
From March 31 to April 2, two of the eight task forces of the Asia-Pacific
Partnership on Clean Development and Climate (APP), namely, the Power
Generation and Transmission Task Force and the Cleaner Fossil Energy Task
Force, held a joint meeting in Melbourne, Australia.
As I commented earlier on several occasions, APP activities are established
through the participation of both the government and private sectors of seven
countries in the Asia-Pacific region as partnerships for addressing issues such
as growing energy demand, energy security and climate change.
The Power Generation and Transmission Task Force places particular
importance on peer review activities proposed by Japan. These activities consist
in cross-national programs for engineers in various countries to exchange visits
to one another’s coal-fired power plants with the aim of sustaining or improving
the thermal efficiency at those plants by suggesting improvements in plant
operation and maintenance.
The task forces conducted a peer review project in India in February in which we
made such suggestions to the Indian stakeholders having difficulties coping with
power shortages, indicating specific examples of the large extent to which the
improvement of thermal efficiency at their power plants would contribute to the
mitigation of environmental impacts and the saving of fuel.
Our activities were highly appreciated by the Indian stakeholders, who made the
following comment: “The efforts to improve the thermal efficiency of our existing
power plants—and thus enabling lower electricity prices—are highly significant
for us. Considering the additional benefit of reducing CO2 emissions, we wish to
spread such efforts all over India.”
This recent meeting of the task forces, convened in recognition of these
achievements, was attended by about one hundred representatives from the
governments and electric power sectors of all APP countries except China (the
United States, India, Australia, Canada, South Korea and Japan), where various
achievements were reported and new projects were proposed.
In these discussions, we proposed that each country should use a common
model to quantify the CO2 abatement that would be possible through efficiency
improvements and similar efforts. Such quantification would enable us to present
in visible terms how effectively our peer review activities, which are the core of
the sectoral approach by the power sector, may reduce CO2 emissions.
Our proposal was highly appreciated by the United States and Australia, and the
participating countries agreed to start developing concrete programs following
the establishment of a contact group for negotiations on details.
As for peer review activities in the future, the third project will take place in the
United States at the end of this month (April 28 to May 2) followed by the fourth
project planned in Australia in late June.
The Third Peer Review Project will address two coal-fired power plants in
Wisconsin, United States. In this project, while pursuing the sharing of past best
practices, we will use a checklist prepared by us to estimate in a quantitative
manner the reduction in CO2 emissions achievable by improving the thermal
efficiency.
2. Interim Reports on the Seismic Back-Check Project
Next, I will comment on the interim reports issued by respective electric power
companies in Japan at the end of last month on the Seismic Back-Check Project.
Electric power companies in Japan have always designed their nuclear power
plants with sufficient safety margins for seismic engineering, and reviewed the
seismic safety of their plants from time to time in reference to the latest findings.
In these interim reports, each electric company reported how the company
reestablished the design basis ground motion for each plant in reference to the
Seismic Design Review Guidelines revised in September 2006, and how the
company evaluated the seismic safety of major installations with critical safety
functions at some representative plants.
Applying the new guidelines that incorporate the latest findings from seismology,
the maximum acceleration as a characteristic of the design basis ground motion
was greatly increased. Moreover, based on information such as findings from the
Niigata Chuetsu Offshore Earthquake, the period of historical active fault
movements to be reckoned was extended from the last 50 thousand years to the
last 120-130 thousand years. Other new factors include investigations focusing
on topographical details such as the bending of ridges and rivers, and the
consideration of at least the presence of active faults that remained
uncharacterized even after elaborate studies. Thus, the evaluations incorporated
broader factors with a more proactive, safety-oriented approach.
The electric power companies in Japan confirmed in these evaluations that the
functions of safety-significant major installations such as shutdown, cooling and
containment would remain intact even under the action of the newly-defined
design basis ground motion.
The validity of these interim reports will be assessed by governmental
committees and by the Nuclear Safety Commission.
We will continue with the back-check project and the systematic employment of
additional measures for increasing seismic safety margins.
3. Change of Vice Chairman
Finally, I would like to mention that Mr. Kondo has retired from the president post
at Hokkaido Electric Power and also from the vice chairmanship at FEPC.
