Failure of control rod support at magnet assembly
- Cornell University, Ithaca, NY (United States)
On October 2, 1975, the Cornell University TRIGA MARK II Pulsing Reactor experienced a failure of the Safety Control Rod Support Magnet Assembly. During routine steady-state operation at 100 kw the reactor was suddenly shut down by what was indicated as a linear power recorder scram. This was later verified to be caused by an electrical transient. After performing appropriate channel checks, attempts to restore magnet current were unsuccessful, even though all scram circuits were reset. The results of circuit tracing revealed a low-resistance-short across the magnet leads of the Safety Control Rod Drive System. Further investigation located the short circuit inside the magnet assembly. A brief account of locating the trouble and method of repair will be discussed. (author)
