Much of the recent research on stress-corrosion cracking of austenitic stainless steels has been stimulated by their use in nuclear reactor coolant circuits. The occurrence of stress-corrosion cracking in boiling water reactors (BWR) has been documented by Fox . A major cause for concern was the pipe cracking that occurred in the sensitised HAZ of the Type 304 pipework, which is reported to have been responsible for about 3% of all outages of more than 100 h from the period January 1971 to June 1977. 

Some hthium compounds are used as rocket propellants, nuclear reactor coolants, alloy hardeners, and deoxidizers and to make special ceramics. 

Dibenzothiophene is stable up to a limit of 425° under neutron bombardment and has therefore been evaluated as an alternative nuclear reactor coolant. Terphenyl, the normal coolant, is slowly polymerized under electron irradiation and the addition of dibenzothiophene partially stabilizes this polymerization process. ...

The most widely known use of lithium is the use of lithium carbonate in treating manic-depressive affective disorders the mechanism by which it alleviates depression in some people is not known. Industrially, lithium and its compounds are used in metal alloys, lubricants, nuclear reactor, coolant, ceramics, alkaline storage batteries, and electronic tubes. It is also used as a catalyst and as a reducing agent. 

OTHER COMMENTS terphenyls are important industrially as chemical intermediates in the manufacture of nonspreading lubricants, as heat transfer fluids, and as nuclear reactor coolants are also used as constituents of waxes and polishes, and as plasticizers for resin-bodied paints para-terphenyl has been used as a component of sunscreen lotion the terphenyls are considered a non-significant industrial hazard due to their low vapor pressure.
