Leakage of water in the primary cooling system of AERE Reasearch Centre

On the morning of 14 July 1997 during the pre-start-up surveillance, it was found that the reactor pool water level had dropped by about 7.5 cm. The loss rate was increasing. On subsequent investigation it was detected that a portion of N-16 decay tank had got corroded/perforated. the leakage rate has presently been contained to 50 gallons per day. Total loss of primary water till to date (24.7.97) is estimated to be about 650 gallons. No fission but the only activated product Co-58 of about 27 Bq/litre so far has been found in the leaked water.

FUEL ELEMENT DROP

A fuel element from F-ring, during routine inspection, was dropped at 12.00 on 30 July 1992 from a height of about 4.25 metres under water to the bottom of the reactor tank. The incident was duly reported to the national nuclear safety committee and was subsequently investigated. Neither any radioactive release to the atmosphere nor any contamination in the tank water was detected. Both the tank bottom and the fuel element appeared to be ok. Operation was restored with a new fuel element in the vacant location.

CAPSULE BREAKAGE IN CENTRAL THIMBLE

This refers to the event reported through the INES Information Service on 24 February, 1993. Investigations have been completed. Lapse/violation in following the prescriptions of the Safety Analysis report is the principal reason of failure. The event, which should be rated level 1, is placed 1 level higher because of this lapse. Necessary administrative steps have already been suggested and are being materialized to prevent repetitions. The CT has been decontaminated and cleaned and the reactor resumed unrestircted operation on 14 March.
