16 Events Involving Radioactive Sources,
Materials with Increased Activity
Recorded in 2019
Sofia, January 10 (BTA) - A total of 16 events involving radioactive sources and materials with increased activity were recorded in Bulgaria in 2019, according to the Annual Report of the Nuclear Regulatory Agency (NRA) that was presented here on Friday. Most events were registered by the automated radioactive control systems installed at the entrances of large metallurgical companies and at border crossings.
In one of the cases, the radioactive cargo, detected at one of the border checkpoints, was returned to the sender, the Agency said. In the other five cases, because of the insignificant radiation levels the cargo was released. In the cases where radioactive contamination was confirmed and the cargo consisted mostly of scrap metal, the cargo was segregated and measures were taken to detect, isolate and eliminate the contamination or the sources of ionizing radiation.
The consequences of the events are eliminated by interdepartmental emergency teams, which are formed on a case-by-case basis and are composed of officials of the competent state bodies: the Nuclear Regulatory Agency, the Health Ministry and the State Enterprise Radioactive Waste, the Agency said.
In 2019, the NRA recorded four operational events at the Kpzloduy Nuclear Power Plant: one in Unit 5 and three in Unit 6. In two of the events in Unit 6, the technological safety systems were actuated. In the other two events, the main circulating pumps shut down after the actuation of the safety systems.
The events at the nuclear plant involved equipment intended for the normal operation of the units with no direct relevance to nuclear safety and radiation protection. The registered events did not impact nuclear safety at Kozloduy and did not lead to violation of operating limits and conditions. The events did not result in any changes in the radiation background in the vicinity of the plant and to overexposure of personnel or members of the public.
All events were rated "Below the scale/Zero Level" on the seven-level International Nuclear Event Scale (INES), which qualifies them as events without safety significance, the Agency adds. The Kozloduy N-plant analyzed all these events in order to implement measures to prevent their recurrence. RY/PP
