4 · The 10 MW high temperature gas-cooled reactor (HTR-10) is the first pebble-bed gas-cooled test reactor in China. A sampling system for the measurement of carbon-14 ( 14 C) was established in the helium purification system of the HTR-10 primary loop, which could sample 14 C from the coolant at three locations.
High-temperature superconductors refer to materials that exhibit superconducting properties at temperatures above 77 K (-196°C). This is significant because 77 K is the boiling point of liquid nitrogen, which is more affordable and easier to handle compared to liquid helium used for cooling many conventional superconductors.

This reveals a fundamental aspect of cooling of such high temperature, partially molten rocks—high-temperature cooling is not necessarily concurrent with exhumation. Indeed, the overall cooling history of a rock consists of contributions from several sources that may be summed up as (Philpotts and Ague 2009 ):
Radiant asymmetry is the difference between the plane radiant temperature of the two opposite sides of a small plane element, and there is a limit of radiant asymmetry in a radiant wall, floor and ceilings.Fanger et al.

Normal engine start, fixed pitch propeller. A minimum engine jacket water temperature of 50°C is recommended before starting the engine and gradually running it up to 80-90% SMCR speed (SMCR rpm) during a 30 minute period. To run up the engine to 90-100% SMCR rpm, it is recommended increasing the speed slowly during a period of 60 minutes.
