一 | TOKYO -- The operator of the Fukushima Daiichi nuclear power plant said the discharge of the second batch of treated radioactive wastewater into the sea ended as planned on Monday, and International Atomic Energy Agency officials in Japan for their first safety and monitoring mission since the release began two months ago said “no issues” were observed.Fukushima Daiichi started releasing treated and diluted radioactive wastewater into the sea on Aug. 24. The operator, Tokyo Electric Power Company Holdings, said the release of a second, 7,800-ton batch of treated wastewater was completed, with its daily seawater sampling results fully meeting safety standards.A magnitude 9.0 quake on March 11, 2011, triggered a massive tsunami that destroyed the plant’s power supply and cooling systems, causing three reactors to melt and spew large amounts of radiation. Highly contaminated cooling water applied to the damaged reactors has leaked continuously into building basements and mixed with groundwater.The release of treated wastewater is expected to continue for decades. It has been strongly opposed by fishing groups and neighboring countries including South Korea, where hundreds of people have protested. China banned all imports of Japanese seafood the day the release began, badly hurting Japanese seafood producers, processors and exporters. Russia recently joined China in the trade restrictions.“I would say that the first two batches of releases went well. No issues were observed," Lydie Evrard, IAEA deputy director general and head of the department of nuclear safety and security, told a Tokyo news conference. She said she visited Fukushima Daiichi on Friday for a firsthand look.Evrard's visit came on the heels of a marine sampling mission by another IAEA team that included scientists from China, South Korea and Canada. She said all participants in that mission said their activity went well. She did not say whether Chinese scientists acknowledged the safety of the release.She said China has been involved in the IAEA safety task force since the beginning of the review that began two years ago and has participated in corroboration activities. The IAEA is aware of China’s concern and engaged with its authorities, Evrard said.Japanese Prime Minister Fumio Kishida, in his policy speech Monday, renewed his call for China to immediately lift its ban on Japanese seafood imports.During the Oct. 16-23 visit, the IAEA sampling team collected seawater, sediment and fish from near the plant and visited a marine laboratory near Tokyo that makes fish specimens for radiation analysis by institutions in and outside Japan, including the IAEA.During Evrard's visit, IAEA task force and Japanese officials are expected to discuss the safety of the ongoing discharge and their future mission plans, with a report expected by the end of the year. She said the discharge plan would be updated with new findings and data collected over the past two months.The IAEA, based on its two-year review of TEPCO's wastewater release plan, concluded in July that if it is carried out as planned, it will have a negligible impact on the environment, marine life and human health.Japan’s government and TEPCO say the discharge is unavoidable because wastewater storage tanks at the plant will be full next year. They say the water produced by the damaged plant is treated to reduce radioactivity to safe levels, and then diluted with massive amounts of seawater to make it much safer than international standards.TEPCO has said it plans to release 31,200 tons of treated water by the end of March 2024, which would empty only 10 tanks out of 1,000 because of the continued production of wastewater at the plant.。 据龙芯中科官方消息，2022年9月初，UEFI官方组织在新发布的UEFI v2.10规范中，全面支持了龙芯处理器的LoongArch64架构，以及部分LoongArch32架构。近期，龙芯团队又完成了LoongArch基础代码与UEFI上游TianoCore EDK2的合并，从而进入其主分支，成为继x86、Arm、RISC-V之后，第四个官方支持的芯片指令系统架构。UEFI即统一可扩展固件接口，是传统BIOS的进化版，是一种PC系统规格，可扩展固件接口、负责加电自检(POST)、联系操作系统、提供连接操作系统与硬件的接口。TianoCore EDK2则是遵守UEFI规范的一个官方代码实现。代码合并有什么意义呢？一是开发者可以直接获取LA基础代码。合并后，开发者可以在开源社区直接获取LoongArch的基础支撑代码，从而直接编译LoongArch的外围驱动，无需再从龙芯获取开发环境。二是有助于LoongArch虚拟机开源。虚拟机代码开源以后，开发者或者用户可直接从EDK2社区拿到LoongArch虚拟机代码，编译成功后就可以在业界流行的通用处理器上直接运行LoongArch虚拟机固件，包括LoongArch、x86、x64、AARCH64等。SMBIOS支持LoongArch后，龙芯中科已与多家设备厂家展开联合攻关，打通底层技术链，构建自主创新链。
二 | 龙芯中科表示，未来将持续关注UEFI、EDK2动向，在TianoCore EDK2上持续贡献、优化LoongArch代码，使LoongArch在EDK2上的实现趋于完善。龙芯中科还计划将LoongArch部分物理机代码二进制化，更好地服务LoongArch生态开发和建设的公司和个人。
