`The claim that people could penetrate the Kozloduy nuclear power plant is absurd,` Ivan Khinovski, Bulatom Association Chairman said. `This is known by anyone familiar with the protection of the shops and laboratories in which nuclear fuel is involved in the work,` he added. According to him, Bulgaria`s efforts must be directed towards working out a strategy for a topical safety level of the third and fourth reactors, and extending the term of their exploitation even after 2006, as well as towards working out a concept on the modernization of the fifth and sixth reactors. `Only in this way will Bulgaria be able to preserve its place as a power engineering centre in the Balkans,` Khinovski stressed.
