INES 1: Anomaly

Impact on Defence-in-Depth
  • Overexposure of a member of the public in excess of statutory ­annual limits.
  • Minor problems with safety components with significant defence-in-depth remaining.
  • Low activity lost or stolen radioactive source, device or transport package.
(Arrangements for reporting minor events to the public differ from country to country. Also, it is difficult to ensure precise consistency in rating events between INES Level-1 and Below scale/Level-0)

Loss of a device containing radioactive sources

On the 25th of August 2016 the lack of two density gauges containing a category 5 radioactive source each (Am-241 activities 240 MBq and 185 MBq) was discovered at a former barite mining facility. The gauges were not in use and were to be disposed of. The gauges were supposedly stolen but the exact date of the theft is not known due to the licensee’s lack of proper documentation. There is no evidence of possible exposure of individuals.

A sealed radioactive Cs-137 source contaminated the premises of waste management company

Event Abstract:
A sealed radioactive Cs-137 source contaminated the premises of waste management company and also the neighboring rooms used by Finnish Radiation and Nuclear Safety Authority (STUK). The event was found out on 7 March 2016.

The source, activity presently 360 MBq, had been used in a factory in Finland for level gauging and was delivered to waste management company as radioactive waste. When the gauge was received by the company, one of the staff tried to open the source shield in order to remove the actual cesium source for disposal. He did not have information or other indication that the source might not be intact. During the handling of the source contamination was released into the room where gauge was handled and also to adjacent rooms and air exhaust ventilation ducts.

Leak from primary coolant system at Kakrapar Atomic Station-1

On March 11, 2016, Kakrapar-1 was operating at 220 MWe. At about 0852 hrs, primary containment (pump room) pressure high alarm appeared in control room. Both fast acting reactor shutdown systems and liquid poison injection system actuated automatically and brought the reactor to long term sub-critical state. Emergency Core Cooling System (ECCS) actuated as per design and provided cooling to the core.

As per the established procedure, plant emergency was declared at 0910 hrs.

Shutdown cooling loop was taken in service and primary coolant temperature was brought to 45 °C.
