The problem of design of power-reactor vessels for safely and durability requires careful application of existing industrial experience and engineering fundamentals to assure adequate consideration of the new problems which arise. Internal heat generation in structural materials, radiation-induced changes in mechanical properties, thermal shock and strain cycling, and coolant-dissociation effects on corrosion and embrittlement all present problems which require close attention. The hazards of mechanical failure and the cost and difficulty of repair place a high value on safety and reliability and justify comprehensive structural-design criteria and evaluation coupled with close control of material and fabrication quality. An uncommon problem associated with the pressure-vessel design is analysis of the consequences of conceivable accidents due to reactor runaway, or in some cases due to a nondetonating chemical reaction. In some cases a pressure-tight building is provided to prevent spread of radioactivity. The problem of penetration of the enclosure building by missiles from the pressure vessel then requires careful evaluation (auth)
