Former US Nuclear Regulatory Commission chairman Gregory Jaczko yesterday said that nuclear energy is playing an increasingly insignificant role in electricity generation worldwide, and that, contrary to popular belief, it is actually more expensive than a range of methods of energy generation.
At a news conference in Taipei, Jaczko said that the future for nuclear power generation in the US and worldwide is one of “decreasing use and eventual phase-out.”
Referencing data generated by the US commission, Jaczko said that even if all US nuclear power plants were able to renew their operational licenses, the use of the energy source in the nation would come to an end by about 2055.
Diminishing use of nuclear power is a global trend, with just about 70 reactors under construction worldwide — a small fraction of operational reactors worldwide, he said, adding that the majority being built are in China.
The number of new plants is much lower than the number of facilities scheduled to be decommissioned, he said.
“The countries that have nuclear power plants are not building anywhere close to the amount of plants they need to replace existing plants,” Jaczko said. “Given the long lead time to build the plants, the cost and other factors, it is unlikely that nuclear energy will play a significant role in electricity generation in the next several decades.”
There is more than enough time for governments to look into alternative technologies without compromising their carbon reduction goals, he said, adding that global energy use is expected to grow significantly over the next 30 years.
He said that energy from nuclear power plants is not as inexpensive as advocates claim.
Referring to a chart compiled by the US Energy Information Administration in 2013, Jaczko said that the “total system levelized cost” for power plants utilizing advanced nuclear energy stood at US$108.40 per megawatt-hour (mWh), while for plants generating power from natural gas with carbon sequestration technology or from geothermal sources, costs were US$93.40 and US$89.60 per mWh.
The estimates skip the money required for nuclear waste disposal and site decommissioning, which constitute the most expensive part of such plants, he added.
Asked to comment on a plan by the state-run Taiwan Power Co to ship nuclear waste to France to be reprocessed, which has been proposed based on an agreement for cooperation between Taiwan and the US, Jaczko said that nuclear waste of US origin must gain US approval before it can be exported.
“Just because it is in the agreement does not mean it has to be done,” he said, adding that Taipower’s plan “does not make any sense.”
LOUD AND PROUD Taiwan might have taken a drubbing against Australia and Japan, but you might not know it from the enthusiasm and numbers of the fans Taiwan might not be expected to win the World Baseball Classic (WBC) but their fans are making their presence felt in Tokyo, with tens of thousands decked out in the team’s blue, blowing horns and singing songs. Taiwanese fans have packed out the Tokyo Dome for all three of their games so far and even threatened to drown out home team supporters when their team played Japan on Friday. They blew trumpets, chanted for their favorite players and had their own cheerleading squad who dance on a stage during the game. The team struggled to match that exuberance on the field, with
Taiwanese paleontologists have discovered fossil evidence that pythons up to 4m long inhabited Taiwan during the Pleistocene epoch, reporting their findings in the international scientific journal Historical Biology. National Taiwan University (NTU) Institute of Ecology and Evolutionary Biology associate professor Tsai Cheng-hsiu (蔡政修) led the team that discovered the largest snake fossil ever found in Taiwan. The single trunk vertebra was discovered in Tainan at the Chiting Formation, dated to between 400,000 and 800,000 years ago in the Middle Pleistocene, the paper said. The area also produced Taiwan’s first avian fossil, as well as crocodile, mammoth, saber-toothed cat and rhinoceros fossils, it said. Discoveries

Whether Japan would help defend Taiwan in case of a cross-strait conflict would depend on the US and the extent to which Japan would be allowed to act under the US-Japan Security Treaty, former Japanese minister of defense Satoshi Morimoto said. As China has not given up on the idea of invading Taiwan by force, to what extent Japan could support US military action would hinge on Washington’s intention and its negotiation with Tokyo, Morimoto said in an interview with the Liberty Times (sister paper of the Taipei Times) yesterday. There has to be sufficient mutual recognition of how Japan could provide
