The International Atomic Energy Agency (IAEA) said Pyongyang had refused to allow agency experts to take samples of the 8,000 spent uranium rods, which might have thrown light on the history of North Korea's suspect nuclear programme. 2 May 1996 (Reuter) - French infants streamed back into a school near Paris, after parents lost a new round in a battle to have it closed due to radioactive leaks linked to the work of Nobel laureate Marie Curie. The kindergarten was built in 1969 on a site used by Curie to do pioneering experiments to extract radium which was later used to treat cancer via radiotherapy. Curie herself died of radiation poisoning in 1934. 2 May 1996 (Reuter) - Five new nuclear power plants came into operation since 1994 and a mothballed plant in Armenia came back on stream, bringing the total number around the world to 438, the United Nations nuclear agency said. Four new reactors with a combined capacity of 3,290 megawatts of electricity were connected last year to power grids in India, South Korea, Britain and Ukraine, the Vienna-based International Atomic Energy Agency (IAEA) said.
