, a nuclear plant No. 1, Shimen District, Shimen District, Taiwan, has expired today (5th) and has entered the shutdown stage according to law. It has officially entered the retirement period from the 6th. It has unloaded the 40-year power generation task since 1978 (cumulative power generation is about 162.5 billion kWh), and is also the first nuclear power unit in Taiwan to be retired.
Taiwan said that nuclear plant is one of the top ten construction projects in Taiwan. In addition to assisting the economic impact caused by the oil crisis in the 1970s, has also improved Taiwan's investment environment in the long run and became the basis for industrial transformation. . TAIwan also thanked the New Taipei City Government and Shimen villagers for providing valuable land and resources. The retirement plan for the No. 1 aircraft of the
nuclear plant was approved by the original energy association review on June 28 last year. It is now waiting for the environmental assessment review of the Environmental Protection Agency. After obtaining the original energy association retirement license, a 25-year retirement operation will be officially launched. The regulations stipulate that the retirement of nuclear power plants will be carried out in a "immediate demolition" manner, and the retirement work will be planned in the future for four phases of procurement.
However, Taiwan Power is still increasing its budget for retirement.
Taipec Company originally estimated in 2010 that the total number of NT$335.3 billion is required for nuclear power plants to be decommissioned, nuclear waste disposal, disposal and transported. However, the cost was added to 470 billion yuan at the beginning of this year. Media reports also pointed out that the latest assessment of the retirement of each nuclear power plant of NT$140 billion. With the final disposal of nuclear waste , the total cost of retirement of NT$3 nuclear power plants is as high as NT$620 billion, but the spokesperson of NT$1 spokesman was unwilling to confirm this figure in an interview, and only stated that it is still under approval by the Ministry of Economic Affairs.
In order to deal with nuclear waste, the six nuclear energy units of Taiwan Power Nuclear Corporation's 1, 2 and 3 have been allocated 0.14-0.18 yuan from an average of 1 kilowatt-hour of electricity to be issued as the "nuclear back-end fund" as the future retirement of nuclear power plants, such as nuclear waste disposal, storage, disposal and transportation. The accumulated nuclear back-end funds of the three nuclear power plants have a balance of 317.489 million yuan in October this year. However, as nuclear power plants will be retired one after another, nuclear back-end funds will inevitably continue to decrease in the future, but compared with the 470 billion yuan retirement expenses recognized by Taiwan Power, it is currently 152.6 billion yuan less.
fuel rod cannot be moved out, and 700 million more burned every year
Why is the exact number of retirement so difficult to calculate? In addition to the possibility of postponing service in the future, the main reason is that the Nuclear Plant 1 is currently "unable to retire" due to the subsequent storage operations of the fuel rods, and the related costs will also increase.
electric power said that the current cost of decommissioning of nuclear plant 1 is about 30 billion yuan, but the fuel used in nuclear plant 1 is currently placed in the furnace core and used fuel pool respectively. The reactors of machines 1 and 2 each have 408 fuel rods, and a total of 816 fuel rods must be removed from the reactor before decommissioning can be implemented.
power units were originally planned to move the used fuel rods to outdoor dry storage facilities on January 1, 2019. The first phase of dry storage facilities was also built in 2013, but the New Taipei City Government has not issued a "soil and water conservation completion certificate" so far and determined that the entire case has expired.
has no outdoor dry storage to store, and the fuel rod will continue to be placed in the reactor. Even if the reactor does not generate electricity, it still needs to maintain a certain temperature and pressure. All cooling water systems, emergency power systems, and safety systems must be maintained. Fuel pools, reactors, reactor plants and other related facilities will not be decommissioned. Although Taiwan Power plans to build the indoor dry storage facilities of the first phase of the nuclear plant, it will take about 10 years and will be completed by the end of 2028, which will not keep up with the retirement time of the first nuclear plant.
electric power pointed out that if the fuel rod removal is delayed until the second phase of indoor dry storage is completed, the reactor core fuel will begin to be removed in December 2028. The original planned 25-year retirement progress will be delayed for 6 years, and the additional maintenance cost will be 11.4 billion yuan. If the final site is required by the New Taipei City Government, dry storage will be agreed to be enabled (Taiwan Power Plant’s final disposal site selected by used fuel rods in 2038), and it is estimated that the retirement will be completed in 2063, and the completion date will be 19 years slower than the original plan.
power stations also pointed out that if the retirement operation cannot be completed within 25 years, the delay time will be unestimated.
However, the New Taipei City Government, which has become a target of archery because it does not emit water, responded again today.
What is New Taipei City "dissatisfied with"?
In the face of the accusations from Taiwan Power and the Ministry of Economic Affairs, New Taipei City spokesman Zhang Qiqiang said that the most important key to nuclear power is safety. Whether the location of the dry storage site or the geological conditions are appropriate, some experts have even suggested that TAI should refer to European countries for indoor dry storage, but unfortunately TAI is completely deaf.
Agriculture Director Coco Lee said that the first phase of nuclear power plant was built outdoors in nuclear power plant. Taiwan Power applied for completion in 2012, but "when my colleagues went to the scene at that time, it was really hard to believe that this was the situation when a nuclear power plant was completed."
Coco Lee said that Taiwan Electric applied for water protection, but did not construct according to the drawings. The dry storage yard was in an unsafe and illegal construction situation. At that time, Taiwan Electric had been fined 60,000 yuan in accordance with the Water Protection Law and asked for another change. However, until the construction deadline in September 2013, although TAI power had 12 changes to the plan, it did not make any specific corrections in the main direction. "It was just that it had been sending the unapproved water conservation plan to be approved by New Taipei ." Coco Lee said that as he saw that the legal completion deadline had arrived, he had to make a decision not to approve it.
Zhang Qiqiang further explained that there is Ganhua River near the dry storage site, and the upper reaches of Ganhua River are the potential area for earth and rock flows. Taiwan Power only serves as a test area within 1 kilometer of Qianhua River, which does not comply with the regulations. In addition, the groundwater level involves designs such as earth walls and drainage. Taiwan Electric only reported the groundwater level by 5 meters, which is more than 60% short-term than the 7.7 meters measured by New Taipei City.
Cai Yaying, a lawyer who continues to pay attention to the retirement process of Nuclear Factory 1, also pointed out in an interview that open-air storage has always been suspected of falling earth and rocks and falling earth and rocks, and various risks nearby. Although the construction passed the environmental impact assessment, the dry storage location is close to the mountain. "I planned to be an outdoor dry storage site. Many years ago, everyone talked about whether to directly do indoor dry storage. Nuclear Factory 1 is close to the sea, and the sea breeze is corroded, and the wind blows and sun is exposed to rain. There is a risk of soil and rocks falling next to the mountain." She also It pointed out that a severe rain disaster occurred on June 2, 2017. After more than a week, I went to the site to inspect it and saw that the soil and rocks collapsed in the dry storage plant. Although the soil and rocks did not cover the dry storage plant, she said "I am still a little worried."
This is the first time Taiwan has dealt with the retired project of a nuclear power plant. Nuclear No. 1 Director Cai Zhengyi said in an exclusive interview with the media recently that the nuclear power unit is the first retired nuclear power unit in Taiwan, "there is no fixed model to follow." Although the statutory license has expired, the environmental impact assessment of the retirement of Nuclear Plant 1 is still under review. The Environmental Protection Agency plans to hold a second preliminary review meeting of the project team. requires TaiPhone to explain the waste treatment and retirement planning schedule.
