Entergy reduces Massachusetts Pilgrim reactor to clean condenser

Wed Mar 19, 2014 10:29am EDT

March 19 (Reuters) - Entergy Corp reduced the
685-megawatt Pilgrim nuclear power plant in Massachusetts early
Wednesday to clean the condenser, the U.S. Nuclear Regulatory
Commission said in an email.
    Electricity traders said the unit was reduced to about half
power early Wednesday from full power earlier in the day.
    The NRC said the company cleans the condenser on a
semi-regular basis to reduce the buildup of biological material,
such as algae.
    Traders estimated the unit would return to full power in a
day or so.
