4 FAQs about [Micro modular reactors North Korea]

What is micro modular reactor design?

The Micro Modular Reactor design proposed in this paper has 3 meter diameter core ( 2 meter active core) which is suitable for “factory manufactured” and has few tens year of service life for remote deployment.

What is the core power density of a 40 MW reactor?

The core power density for 40 MW design is 6.37MW/m3, and the average heat transfer rate at coolant channel surface is 19 W/cm2. Considering typical heat transfer coefficient of helium, 1,800 W/m2/K, the graphite to coolant temperature drop is 106 K which is quite acceptable value for a high temperature reactor.

What is the core temperature of a gas cooled reactor?

The core temperature is fixed to 800 K which is the typical core average temperature of a gas cooled reactor. The core power density for 40 MW design is 6.37MW/m3, and the average heat transfer rate at coolant channel surface is 19 W/cm2.

What material is used to control a nuclear reactor?

In System 1, the reactor is controlled by absorbing neutrons in the reflector and preventing them form re-entering the core. In System 2, the reactor is controlled by absorbing core neutrons. Control rod material is likely to be a SiC-based or C-based ceramic with boron or a rare earth absorbing material or beryllium (reflector) material.
