日方无视国际社会的强烈质疑和反对，于2023年8月单方面强行启动福岛第一核电站核污染水排海。截 至2025年12月22日第17次排放结束，福岛第一核电站核污染水累计排放量已达约13.3万吨。 （文章来源：新华网） 日本东京电力公司22日公布福岛第一核电站2026财年（2026年4月至2027年3月）核污染水排放计划草 案，该公司计划在2026财年共排放核污染水8次。 根据这份排放计划草案，2026财年计划排放核污染水次数比2025财年多一次，预计8次排放总量约6.24 万吨，含放射性氚总量约11万亿贝克勒尔。2026财年的首次排放计划于4月进行。 ...

Group 1 - A strong earthquake with a preliminary magnitude of 7.6, later revised to 7.5, struck the eastern waters of Aomori Prefecture, Japan, on December 8, causing over 40 injuries and damage to 14 buildings [1][4] - As of December 9, 36 injuries were confirmed in Aomori Prefecture and 11 in Hokkaido, with 7 of the damaged buildings being residential [2][4] - The Japan Meteorological Agency issued a "seismic alert" for the Hokkaido and Sanriku coastal areas, indicating a higher probability of significant aftershocks in the coming week [4] Group 2 - Tokyo Electric Power Company temporarily suspended the discharge of contaminated water from the Fukushima Daiichi Nuclear Power Plant due to the earthquake and tsunami warnings, but resumed operations on December 9 at 14:30 [5] - The current discharge plan, which began on December 4, aims to release approximately 7,800 tons of contaminated water by December 22 [5] - Following the earthquake, a leak of about 450 liters of water occurred at a spent fuel pool in a nuclear fuel reprocessing facility in Aomori Prefecture, although it did not reach outside the building [5]

Core Viewpoint - The planned discharge of nuclear contaminated water from the Fukushima Daiichi Nuclear Power Plant has been halted due to a tsunami warning and seismic activity in the region [1]. Group 1: Incident Overview - A strong earthquake occurred off the eastern coast of Honshu, Japan, on December 8, leading to a maximum seismic intensity of 4 in the surrounding areas of the Fukushima Daiichi Nuclear Power Plant [1]. - Tokyo Electric Power Company (TEPCO) reported that there were no abnormalities detected at the Fukushima Daiichi and Daini Nuclear Power Plants following the earthquake [1]. Group 2: Nuclear Water Discharge Operations - TEPCO had initiated the 17th round of nuclear contaminated water discharge on December 4, which was expected to last until December 22, with an estimated discharge of approximately 7,800 tons of contaminated water [1]. - As of the 16th discharge, the cumulative amount of discharged contaminated water has exceeded 125,000 tons [1]. - The 18th discharge is anticipated to take place around March 2026 [1].

Core Viewpoint - China has suspended the import of Japanese seafood due to Japan's failure to provide promised technical materials regarding product safety, which has led to a significant decline in Japanese seafood exports to China [1][3]. Group 1: Impact on Japanese Seafood Exports - Japan's agricultural and seafood exports are projected to decline for the first time in four years, with a year-on-year decrease of 1.8% in the first half of 2024, totaling 701.3 billion yen (approximately 70.13 billion yuan) [3]. - Exports to mainland China have plummeted by 43.8%, amounting to only 78.4 billion yen, with seafood exports experiencing a dramatic drop of 92.3%, reduced to just 3.5 billion yen [3]. Group 2: Domestic Market Response - Japanese seafood's market share in China is already low, and many restaurants have alternative sources for ingredients, indicating minimal impact on local dining establishments [3]. - Major retail chains have largely ceased importing Japanese seafood since the nuclear wastewater discharge incident, with a shift towards sourcing local seafood products instead [1][3]. Group 3: Market Reaction - Following the announcement of the import suspension, the seafood sector saw a collective surge, with several key stocks hitting the daily limit up, including Guolian Aquatic (300094.SZ) and others [3].
