27.   He said the leak came from a heater used to remove moisture from the steam generated in the reactor core, but did not involve the core itself.

28.   It ignited an explosion, fire and partial meltdown of the reactor core.

29.   Khatami told plant directors Iran will sign a contract for a second reactor core once the first is delivered, ORT reported.

30.   The nozzles are vertical tubes that house the rods, which absorb excess neutrons in the reactor core.
