Item 5. Other Events - -------------------------- The Nuclear Regulatory Commission (NRC) today placed Illinois Power's Clinton Power Station (Clinton) on its Watch List. The NRC places nuclear plants on its Watch List when it believes additional regulatory oversight is required because of declining performance. Twice a year the NRC evaluates the performance of nuclear power plants in the United States and identifies those which require additional regulatory oversight. Once placed on the Watch List a plant must demonstrate consistent improved performance before it is removed from the list. The NRC will monitor Clinton more closely than plants not on the Watch List. This may include increased inspections, additional required documentation, NRC-required approval of processes and procedures, and higher-level NRC oversight. Illinova Chairman Larry Haab said he does not consider the announcement a new signal. "It is a confirmation of the situation over the last few months and not a forecast for the future. This news, while unpleasant, was not unexpected; the problems at Clinton are well documented" said Haab.
