China Huaneng Group currently operates HTR-PM, a 250 MW HTGR power plant in Shandong province, China. The high operating temperatures of HTGR reactors potentially enable applications such as process heat or hydrogen production via …

HTR-Module安全概念的特点是，即使在极端的假设的事故条件下，也可以通过被动系统特性对环境进行全面的保护。 HTR的安全功能特征是根据这样的设计条件：即使在所有主动冷却系统失效和冷却剂完全丧失的情况下，最大的燃料元件温度仍将低于1600℃限值，以 ...

The HTR-PM (Chinese: 球床模块式高温气冷堆核电站) is a Chinese small modular nuclear reactor. It is a high-temperature gas-cooled (HTGR) pebble-bed generation IV reactor evolved from the HTR-10 prototype. The technology is intended to replace coal-fired power plants in China's interior, in line with the country's plan to reach carbon neutrality by 2060. [1]

High-temperature gas-cooled reactors (HTGRs), also known as very-high-temperature reactors (VHTR) are Generation IV reactors that can operate at very high temperatures and use a graphite-moderated gas-cooled nuclear reactor with a once-through uranium fuel cycle.

高温气冷堆（High Temperature Gas Cooled Reactor/HTGR）, 是一种石墨慢化氦气冷却的反应堆设计。现在国内在建的HTR-PM实际是高温气冷堆中的一种，球床堆（Pebble bed reactor）。

2021年4月2日 · 高温气冷堆 (HTGR)和超高温气冷堆 (HTGR/VHTGR)是最具发展潜力的先进堆型之一，被国际核能界列为第四代核能系统重点研发的6种堆型之一。 高温气冷堆的突出特点是采用耐高温的陶瓷型包覆颗粒燃料元件。 包覆颗粒燃料的核芯是直径约为500 μ m的二氧化铀燃料颗粒，核芯外围是多层包覆层。目前, 国际上比较先进的技术是四层包覆技术，称之为TRISO (tristructural-isotropic)包覆燃料颗粒。 多层包覆构成了非常可靠的小压力壳，将裂变产物阻留 …

HTRGs are modular in construction and are coupled to a heat transportation system which extracts the heat from the helium and make it available for several applications. HTGRs are inherently safe because the fuel pellets have a negative temperature coefficient in that the rate of nuclear reactions goes down with rising temperature.

2006年3月1日 · In the “HTR-N” project of the European Union Fifth Framework Program, analyses have been performed on a number of conceptual HTGR designs, derived from reference pebble-bed and hexagonal block-type HTGR types. It is shown that several HTGR concepts are quite promising as systems for the incineration of plutonium and possibly minor actinides.

2006年3月1日 · Aimed at future usage of an HTR, research and development of hydrogen production using high temperature from an HTR is under research. Parallel to the development of reactor design, work to improve the fuel element manufacture technology and to expand its production capacity is also carried out.

1986年，高温气冷堆项目被列入 “863” 国家高技术研究发展计划，目标是在核研院建设一座功率为10兆瓦的高温气冷实验堆（HTR-10）。 经过了大量研究、验证和一系列关键技术突破，HTR-10于1995年6月在清华大学核研院动工兴建，2000年12月建成临界；2003年1月完成满功率并网发电及系列运行试验和安全试验。...
