Minnesota May Be Next to Support Nuclear Plants

April 1, 2018

Following the lead of Illinois and New York, which have enacted policies supporting nuclear power plants, the Minnesota Legislature is weighing a bill that could help the owner of two nuclear facilities within its borders.

Minnesota is home to the single-unit 671-MW Monticello nuclear plant and the dual-unit 1,100-MW Prairie Island plant (Figure 1). Xcel Energy owns a 100% stake in both of them.

Unit 1 began operation in December 1973 and Unit 2 followed in December 1974. The reactors are licensed until 2033 and 2034, respectively. Courtesy: Nuclear Management Co.

Current Minnesota regulations require investor-owned utilities, such as Xcel, to file multi-year integrated resource plans (IRPs) with the Minnesota Public Utilities Commission (MPUC). Companies give details about their future generation mix in the IRPs. Once the MPUC approves the plan, the utility decides how much money to allocate toward capital, and operations and maintenance expenses at each of its generation facilities.…

Trump Budget Backs Nuclear, Coal; Cuts Funding for Renewables

The Trump administration’s fiscal year 2019 budget request released February 12 asks for more money to support fossil fuel-based power systems, but seeks funding below current levels for other energy initiatives, including renewable energy and energy efficiency.

The energy funding is part of a $ 4.4 trillion budget that features large increases in military spending, along with deep cuts to several domestic programs and entitlements, including Medicare, Medicaid, food stamps, and Social Security disability payments. Analysts immediately said it has little chance of being enacted by Congress as written, in part because of fears of what the proposal would add to the federal deficit over the next decade. A New York Times analysis said the proposed budget would add $ 984 billion to the federal deficit next year, and add about $ 7 trillion to the federal deficit over the next 10 years.

The proposal, Trump’s second since taking office in January 2017, is similar in many ways to his administration’s proposed 2018 fiscal year budget, which was rejected by Congress.…

Nuclear Power, Carbon Capture Winners in New Budget Deal

The budget bill passed by Congress and signed by President Trump in the early hours of February 9 extends a host of tax credits for energy technologies, including provisions to help the Vogtle nuclear expansion in Georgia as well as U.S. carbon-capture projects.

The legislation also provides support for renewable energy, including for small wind turbines and geothermal pumps. It also gave five-year tax credit extensions to small natural gas technologies, including combined heat-and-power (CHP) and microturbines, along with fuel cells.

The Senate version of the bill reportedly included proposals to boost offshore wind energy, energy storage, waste heat to power, and large-scale geothermal generation projects. None of those efforts survived in the House and are not included in the final legislation.

The bill also includes $ 2 billion to help with rebuilding the electricity grid in Puerto Rico, where about 30% of the island remains without power after hurricanes Irma and Maria battered the Caribbean last September. Those funds are part of $ 89 billion in disaster funding for U.S.…

Exelon Will Close Oyster Creek Nuclear Plant Earlier than Anticipated

Exelon Generation will shutter its Oyster Creek Generating Station in October 2018—more than a year before it is required to close the single-unit reactor as part of an agreement with the state of New Jersey.

Exelon agreed in 2010 to close the unit by December 2019—10 years before its license to operate expires—after it decided against installing a cooling tower technology required by the New Jersey Department of Environmental Protection. On February 2, the company said it would permanently close the unit at the end of its current operating cycle in October. The revised schedule will allow Exelon to better manage resources in a market environment where fuel and maintenance costs are rising amid historically low power prices, it said.

Bryan Hanson, Exelon president and chief nuclear officer, noted in a press release that the company will offer a position to every employee at Oyster Creek that chose to stay with the company, and that the revised schedule would give the company time to do that.…

Exercise Proves Hacking a Threat to Nuclear Power Plants

January 30, 2018

| Industry News

Cybersecurity is a topic covered frequently in the pages of POWER magazine, and one that all power plants need to take seriously. A recent simulation proved that the consequences of a hack can be grave.

The drill took place in Sweden, but could have been conducted anywhere in the world. The attack used plant control systems against themselves to flood a cooling system, showing that hacking of computer systems can lead to physical plant damage.

Some experts, including Robert M. Lee, founder of cybersecurity firm Dragos, believe cyber incidents go underreported in the nuclear sector. The reason is that the Nuclear Regulatory Commission only requires the reporting of incidents that affect the safety, security functions, or emergency preparedness of the plant.

Although air-gapping systems, that is, keeping them disconnected from the internet, offers some protection, it is not the complete answer. Viruses, such as Stuxnet, have proven that systems can be infiltrated using USB drives, contractor laptops, or through a host of other seemingly innocuous methods.…
