Entergy Arkansas Incorporated is extending a planned maintenance outage on the 842-megawatt (MW) Unit 1 at the Arkansas Nuclear One plant in Russellville, Arkansas. The outage covers refueling and maintenance; balance-of-plant maintenance; cooling system inspections; steam generator and reactor head inspections; maintenance on coolant pumps, fans, motors and piping systems; control rod adjustments; instrumentation and controls calibrations and testing; turbine generator inspection and testing; and oil-system lubrication.

Irving Oil restarted the 150,000-barrel-per-day (BBL/d) Crude 3 Unit, which was included in the fall turnaround event known as “Operation Red Fox,” at its 300,000-BBL/d refinery in Saint John, New Brunswick, on Sunday, November 13. The associated 55,000-BBL/d Vacuum 3 Unit will remain offline for an additional three to four weeks from this past weekend, as repairs are being made following a vacuum tower fire on Sunday, October 30. All other units, which include the 24,000-BBL/d Naphtha Hydrotreater Train 1, the 24,000-BBL/d Naphtha Hydrotreater Train 2, the 25,000-BBL/d Rheniformer 2 and the 40,000-BBL/d Diesel HDS 135 units, have been restarted and are back online.

Natural Gas

TransCanada Corporation has halted its open season for a new fixed-price toll proposal to flow natural gas along the Canadian Mainline from the Empress receipt point in Alberta to the Dawn hub in Southern Ontario. The open season for the proposed service resulted in bids that fell well short of the volumes required to make the proposal viable, according to the company.
