START-UP OF A CARBON STEEL LOOP
The construction, testing, operational shakedown experiences, and techniques of carbon steel reactor coolant loop startup are described. Normal fabrication techniques were used in loop construction; however, the carbon content was limited to 0.35%. The loop was used intermittently between 1956 and 1958 when it was operated at 270 C and 13O0 psi at pH 10 as a part of the 1706- Ker Coolant Testing Semiworks. Radiation from the loop wag low. Since completion, some of the piping surfaces were covered with a layer of black friable material which is thought to have caused valve failures, although it has caused no trouble in strainers. It is pointed out that the data are based on a relatively short term, generally at non-equilibrium conditions, and that any extrapolations must be made with reservations.
