The Studsvik board decised to close the two research reactors in Studsvik. The reason for closure is said to be unprofitable business. Around hundred employees are affected by this decision. The shut down will take place after the annual outage next summer. Ongoing projects will be continued with the Halden reactor in Norway.
The decommissioning costs are covered by the yearly fee payed by the nuclear power industry, where the so called Studsvik fee is intended for the closure of the reactors.

Fire in fan room at the melting plant in Studsvik. None of the personnel were hurt and there was no measurable rise in radioactivity in the plant. Operations at the plant are expected to resume within a few weeks.

An incident involving the transportation of the radioactive isotope iridium-192 from the Studsvik research reactor in Sweden to New Orleans has been provisionally rated INES level 3. A type-B package containing 366 tera-bequerels (TBq) of iridium-192 was found to have high radiation levels. A man, who conducted a radiation survey on the container on its arrival at New Orleans and then transported it 1-2 miles to its final destination, is calculated to have received some 3.4 mSv of radiation. He thought the high readings on his dosimeter were due to a faulty instrument.

11 of 49 casks moved last year had radiation readings above the limit of 4 Bq/cm². Levels above 400 Bq/cm² have been recorded on casks sent in previous years; The highest was 557 Bq/cm².
The highest contamination in 1997 was 115 Bq/cm² on one cask.

The Swedish cask contamination parallels revelations of contamination levels ranging up to 13.000 Bq/cm² in France.

SKB has taken 27,000 test measurements on the 1,100 casks that have so far been transported to CLAB. Three casks from Studsvik showed levels above 40 Bq/cm² . Of the casks from the plants, 446 were measured at levels between 4 and 40 Bq/cm², 24 were between 40 and 400, and three, above 400 Bq/cm².

Three people decontaminating radioactive metal scrap were burned February 17 in an explosion.
Five people were heating three tons of metal scrap from OKG, which owns the Oskarshamn station, in an oven to separate radioactive material from the metal when the explosion occurred. About half a ton of metal was still in the oven at the time.
It appears that the metal exploded, rather than the oven. The accident appeared to be due to technical failure.

Swedish radiation protection officials are investigating the cause of an incident which put a university research engineer over the annual 50 milliSievert (mSv) (5 rem) dose limit.
The incident happened in an Uppsala University laboratory at the Studsvik research facility. The engineer was adjusting an ion ray from Studsvik's R-2 research reactor. His collective dose between January and September had already reached 23 mSv.
The incident has been classified at Level 2.
