Abstract

Modular high-temperature gas-cooled reactor (MHTGR) has distinct advantages in the sense of the inherent safety, economy property, high electricity efficiency, potential usage for hydrogen production, and etc. Chinese design of MHTGR, named as High Temperature Gas-Cooled Reactor-Pebble bed Module (HTR-PM), based on the technology and experiences of the HTR-10, is under the standard design phase. And the HTR-PM demonstration plant is planned to finish the construction in 2010. The main philosophy of HTR-PM project is safety, standard, economy, and proven technology. The works in the categories of market, organization, project and technology is done in predefined order. And the biggest challenge for the HTR-PM is to ensure the economical competition while maintaining the inherent safety. As a result of optimization and compromise, a design of 450MWth annular pebble bed core is presented in this paper.
