The international community has stopped the practice of shipping nuclear waste overseas for reprocessing, and state-run Taiwan Power Co’s (Taipower) plan to do so is just delaying nuclear waste management, French nuclear safety expert Yves Marignac said yesterday.
Speaking at a news conference in Taipei, the director of French non-profit nuclear energy consultancy World Information Service on Energy (WISE-Paris) said that Taiwan’s spent fuel pools reaching capacity and Taipower’s plan to reprocess highly radioactive nuclear waste are two separate issues that should not be discussed in the same context.
Taipower in February issued an online call for bids to solicit overseas contractors to reprocess about 1,200 bundles of spent fuel rods from the Jinshan and Guoshan nuclear power plants in New Taipei City, for which the company has requested a budget of NT$11.25 billion (US$362.9 million).

Taipower officials have said that the project is a “contingency plan” to resolve storage problems arising from the New Taipei City Government’s rejection of the company’s dry-cask storage project because of safety concerns.
Marignac said it is wrong to consider nuclear waste reprocessing or any interim waste management options, as any nuclear waste management plan should be viewed from a long-term perspective, instead of seeking expedient, short-term solutions.
He said that most countries that used to provide nuclear waste reprocessing, such as the UK and Russia, are either phasing out or have abandoned the technology.
Furthermore, countries that used to ship nuclear waste abroad for reprocessing — such as Germany, Belgium, Italy, Japan and Switzerland — have abandoned the practice, he said.
They ended the practice because 30 to 40 years after nuclear waste is reprocessed, they still have to deal with the remaining radioactive materials, such as plutonium, Marignac said.
With only one nuclear reactor of a Dutch firm still relying on overseas nuclear waste reprocessing, he said that Taipower’s plan is one aimed at “raising the dead.”
As for Taipower Department of Nuclear Back-end Management director Wu Tsai-ji’s (吳才基) comment that the overseas reprocessing plan was “experimental” and would involve only a small batch of spent fuel rods, Marignac said that the “experiment” would require at least 20 years before coming to any conclusions, and the time would be better spent exploring other ways to address the problem.
Taipower’s proposal would only complicate nuclear waste management, as Taiwan would have to put energy into the reprocessing project and would still face the possibility of radioactive materials being shipped back when the contract expires, he said.
As to news that AREVA has won the Taipower bid, Marignac said that the French nuclear waste reprocessing firm is mired in financial problems and warned of a scenario wherein AREVA demands more fees for its service after the contract is executed.
In response, Wu said that AREVA is not the only company being considered by Taipower.
He said that no radioactive materials would be shipped back to the nation according to a clause in a contract.
“Any remaining materials will be the contractor’s responsibility to deal with, in its own country,” he said.
The contract also contains a clause that says Taipower reserves the right terminate cooperation prematurely if problems should occur, he said.
HIGH STAKES: An attack on Taiwan could prompt a joint response from the US and Japan, and trigger a global conflict that could bring down the CCP, Liu Tai-ying said The Chinese People’s Liberation Army (PLA) would not be able to launch an invasion of Taiwan for at least another 10 years, Taiwan Research Institute founder Liu Tai-ying (劉泰英) said on Friday. To occupy Taiwan, China needs to transport at least 300,000 to 400,000 troops across the Taiwan Strait during battle, but it would lack the ability to do so for at least another decade, said Liu, a former Chinese Nationalist Party (KMT) treasurer and a close aide to former president Lee Teng-hui (李登輝). The challenges that China would face during an attempted invasion of Taiwan would be even greater than those
CHINA CRITIC: Prime ministerial candidate Giorgia Meloni, the front-runner in today’s election, said that she would not renew a Belt and Road Initiative deal with Beijing Italian lawmaker Giorgia Meloni, the front-runner to become the country’s next prime minister, is expected to reverse course on Italy’s support for China’s Belt and Road Initiative and strengthen ties with Taiwan if a coalition headed by her party wins the country’s general election today. “Without any doubt, if there is a center-right government, it is sure that Taiwan will be an essential concern for Italy,” Meloni told the Central News Agency in an interview. Italians are to vote in a snap election triggered by the resignation of Italian Prime Minister Mario Draghi following a failed attempt to get his coalition partners
HAWAII MODEL: While Hawaii held a referendum on becoming the 50th US state, Taiwan has never applied to join the People’s Republic of China, Miles Yu said China comparing Taiwanese independence to Hawaii seeking independence from the US is illogical, as Taiwan has never applied to be a part of the People’s Republic of China (PRC), Hudson Institute senior fellow Miles Yu (余茂春) said over the weekend. Chinese Minister of Foreign Affairs Wang Yi (王毅), who is in New York for the UN General Assembly, has given multiple talks asserting Chinese sovereignty over Taiwan. In a speech to the Asia Society on Thursday, Wang likened Taiwan to Hawaii. “Just as the US would not allow Hawaii to break away,” Beijing “reserves the right” to seek unification, Wang told the gathering.

Taiwanese on average first use pornographic material at the age of 14, an international survey found on Wednesday. Researchers at National Cheng Kung University, who conducted the survey in the nation, said 50.2 percent of Taiwanese respondents said they used pornographic material two to three times per month over the past year. Lin Chung-ying (林宗瑩), an associate professor at the university’s Institute of Allied Health Sciences, said the results indicate that Taiwanese are less sexually active than people in other countries, especially in the West. Taiwanese on average masturbate 10 percent less often than respondents from other nations in the survey, Lin said. The
