Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Numerical simulation and optimal design of fissure karst type high-temperature thermal storage and development
裂隙岩溶型 高温储热开发 数值模拟 优化设计
2023/11/6
我国中低温地热直接利用世界第1，包括温泉洗浴、空间供暖等；高温地热资源储量虽然丰富，但其发电仅排世界第18，利用率不高。裂隙岩溶型地热资源作为主要高温地热资源类型，我国隐伏碳酸盐岩面积达250万平方公里以上，初步估算0-3km深度区间的热能量相当于5000-50000亿吨标煤，雄安是典型地区；同时，我国油气伴生缝洞型地热资源丰富，具有埋藏深、温度高的特点。对此，基于离散缝洞网络模型，形成了考虑渗流...
The Authority for Nuclear Safety and Radiation Protection (ANVS) has granted the final permit to the Central Organisation for Radioactive Waste (Covra) for the construction of a new multi-functional s...
The first HI-STORM FW cask has been placed into the used fuel dry storage facility at the Kr?ko nuclear power plant in Slovenia, officially marking the facility's commissioning, Holtec International a...
Workers at Idaho National Laboratory (INL) have completed the transfer of all the used fuel from the Experimental Breeder Reactor-II (EBR-II) from wet to dry storage, a major milestone under a 1995 ag...
Slovenia's project to build a dry storage facility for used fuel is set to be completed later this year with the transfer of the first 592 used fuel elements.
The new facility is part of the plant's ...
Unlike in humans, when computer “brains” evolve, they get smaller and smaller. This is because the components that perform calculations and consolidate stored information work more efficiently when th...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Minimum storage cooperative regenerating codes for distributed storage
分布式存储 最小存储 协同再生码
