Modular Nuclear Reactors
Published in Yatish T. Shah, Modular Systems for Energy and Fuel Recovery and Conversion, 2019
Three HTR designs in particular—PBMR, GT-MHR, and Areva’s SC-HTGR—were contenders for the NGNP project in the United States. In 2012, Areva’s HTR was chosen. However, the only HTR project currently proceeding is the Chinese high-temperature gas-cooled reactor plant (HTR-PM).

HTR-PM: The first commercial version of the HTGR will be China’s HTR-PM. This reactor is being built in China and will consist of two 105-MWe modules. The reactor will have an outlet temperature of 750°C. This will be a demonstration system for a complete 18-module power station.

The HTR-PM is a pebble-bed-type, high-temperature, gas-cooled reactor for commercial power generation that is being constructed at the Shidao Bay Nuclear Power Plant in China. The main design normal parameters of the HTR-PM are listed in Table II, and the outline is presented in Fig. 4. The helium gas enters the reactor core from the inlet plenum and flows upward in the helium flow channels and downward through the pebble bed before leaving the reactor from the outlet plenum. More details are available in Ref. 1. A 2-D TINTE calculation model has been established according to the HTR-PM reactor structure, as given in Fig. 5.

An HTR-PM unit is under construction at Shidaowan in China’s Shandong province. The China Huaneng Group is the leading organization in the consortium building the Shidaowan HTR-PM demonstration plant, along with the China Nuclear Engineering & Construction Group and Tsinghua University’s INET, which is a research and development leader.15 The HTR-PM is a 458-MW thermal-power, helium-cooled, graphite-moderated reactor with a thermal neutron spectrum. Its primary system operates at 7 MPa, with core inlet and outlet temperatures of 250°C and 750°C, respectively.16
Two-dimensional simulation and experiments of helium discharge between parallel-plate electrodes in short gaps at atmospheric pressure

In High Temperature Reactor-Pebble-bed Module (HTR-PM) now under construction in Shandong province, China, helium gas is the working medium for the main helium blower. The Active Magnetic Bearings (AMBs) and some other electrical equipment also work in helium atmosphere. In the main helium blower of HTR-PM, working temperature of the motor chamber can reach up to 150 °C and the pressure may range from 0.1 to 7 MPa. Because the breakdown voltage of helium is much smaller than that of air in such conditions [1], its discharge should be considered carefully in previous insulation design work.
