From second European conference of TRIGA reactor users; Pavia, Italy (13 Sep 1972). In TRIGA Owners' Conference. A 250 kW cooling system was designed and installed to cool the demineralized water of the IPR-R1 reactor (Triga Mark I). The primary circuit is made of 304 stainless steel. The secondary circuit is made of carbon steel, and the cooling tower of fiberglass. The heat exchanger is of the shell-and-tube type with four tube passes. The demineralized water (primary side) flows through the shell and the ordinary water flows inside the tubes. This arrangement allows cleaning of the tubes (straight tubes) by simply disassembling the top of the heat exchanger. The cooling system was designed to operate at a pool temperature of 40.7 deg C. Cold water returns to the reactor tank in summer days at a maximum temperature of 33.1 deg C. The water flow in the primary side can be varied from 25 m/sup 3//h to 32 m/sup 3//h. Interlocks and prtotection devices coupled to pressure gauges, temperature and water level meters provide a very safe and reliable performance to the cooling system. (4 references) (auth)
