Organic coolant

Robinson and Lurie (1962) reported several other empirical correlations for CHF in organic coolants. These correlations are... 

There are no well-documented studies showing the effects of terphenyls on humans. Clinical studies of an exposed group of workers showed no ill effects from prolonged exposure to 0.1-0.9mg/m. Workers have experienced eye and respiratory irritation at levels above lOmg/m. As a class of compounds, organic coolants (including terphenyls) have caused transient headache and sore throat. In addition, there have been cases of dermatitis attributed to skin contact with organic coolant compounds. ...

Removal of the primary reactor heads revealed warpage over approximately one-half of the upper tube sheet and showed evidence of leakage at a number of points on the bottom tube sheet. Many tubes in the area of the upper tube sheet warpage were burned through while the space between these tubes was solidly blocked with carbon from thermal decomposition of the organic coolant. Review of the reactor design indicated that cooling of the reactor should have been more than...

All of the aspects of organic coolant technology—decomposition, purification, physical properties, fouling, heat transfer, materials performance, and fiammability—were summarized in 1975 (74).

Transfer of undamaged spent fuel cooled in organic coolant to Russia was finished in 1990. It was necessary to develop new technology for the damaged fuel preparation for transport. 

The use of certain organic coolants, such as terphenyls, has been studied in some detail. These have the advantage of permitting operation at lower pressures, on account of their lower vapor pressure as compared with water. They have the additional advantage of being less corrosive than water at reactor temperatures. Their main disadvantage is a tendency to decompose under irradiation and high temperature. 

Cooling by a liquid metal, such as sodium, has been universally adopted for fast breeder reactors. The main reason is that so many potential coolants are unsuitable because of the need to minimize moderation of the fast neutron spectrum in the core. Water (light or heavy) and organic coolants are therefore eliminated. Consideration has been given to the use of steam or helium as fast reactor coolants, but the heat transfer characteristics of a liquid metal are so much more favorable, particularly for a reactor of high power density, that neither steam nor gas cooling has been adopted for current fast breeder designs. 

The use of organic coolant (terphenyl mixtures) in a D20-moderated system has been investigated in the Canadian WR-1 research reactor at Whiteshell, Manitoba. Experience has confirmed that zirconium-based alloys are suitable for extended operation in organic coolant provided there is careful control of the coolant chemistry to prevent excessive hydrogen uptake and fuel tube fouling. 

Zirconium and its alloys also find applications in other nuclear reactor systems, such as gas-cooled or organic coolant-cooled reactors.
