Federal Government uses UPLAN model to examine price volatility in ERCOT

LCG, October 11, 2022--The U.S. Energy Information Administration, or EIA, released its latest supplement to the Short-Term Energy Outlook (STEO) in the Texas market, assessing various possible scenarios using LCG’s UPLAN NPM model, with a special focus on the effects on wholesale power prices and market conditions.

Michigan Governor Supports Reopening Palisades Nuclear Facility

LCG, September 16, 2022--The Governor of Michigan last week sent a letter to the U.S. Department of Energy (DOE) in support of Holtec International’s application for a federal grant under the Civil Nuclear Credit (CNC) program to save the Palisades Nuclear Facility in Southwest Michigan. The federal grant could result in restarting the baseload, carbon-free, nuclear power plant.

Nuclear Regulators Ask Plants Be Inspected for Corrosion

LCG, February 25, 2003The Nuclear Regulatory Agency issued new inspection regulations earlier this month and has restated its intentions regarding plant safety.

Ever since the Davis-Besse plant in Ohio was found to be suffering from nozzle cracks and a hole through its reactor cap from boric acid-related corrosion, NRC has been talking about tougher regulations. The agency issued new rules on the 11th of February, stating that all 60 pressurized water reactors must use chemical or ultrasonic tests to check for cracks and leaks.

The new tests will have to be done at each refueling outage for the most vulnerable reactors.

Initially NRC requested that the reactors be inspected more thoroughly, but when owners said they would run the test once and wait for additional orders, NRC went ahead in mandating inspections, although owners will be allowed to apply for some amount of inspection leeway.

NRC has asked the American Society of Mechanical Engineers to back a permanent rule on inspections but may have to wait several years for this support.

Some reactors have had newer nickel alloy components substituted in, but NRC has said that this substitution does not exempt reactors from inspections as the alloy is too new to be proven as corrosion-resistant.

Radiation from nuclear plant materials and acidic conditions often make metals more susceptible to corrosion, and NRC officials have said that greater focus will be placed on the boric acid in reactors.
