Gas nears $10 a gallon at California station, tops $5 in NYC

A Chevron station in the coastal village of Mendocino about 175 miles north of San Francisco was charging $9.60 a gallon for regular on Friday afternoon.

The Menocino station, Schlafer’s Auto Body & Repair, is the only one in the tourist haven — described on the county website as “an enchanted place filled with real, unspoiled California opportunities” — and is routinely considered the most expensive in the nation.

Owner Judy Schlafer told SFGate.com she paid $50,000 for an 8,880-gallon delivery this week, which she has 10 days to pay for. Three months ago, the same load would have been about $30,000.

Schlafer said that if she didn’t charge $9.60, she’d be out of business. //

Why has the media remained silent even the Post here and Fox on the fact that Under Biden 5 refineries were shut down by the EPA which is part of the driving factor here? That pretty big news since there are not replacement refineries in the works!

Smaller Reactors May Still Have a Big Nuclear Waste Problem | WIRED

A new generation of reactors promises a nuclear energy renaissance, but critics say the US needs to figure out what to do about its radioactive garbage first. //

But there’s a new type of nuclear on the block: the small modular reactor (SMR). For a long time, the US nuclear industry has been stagnating, in large part because of the tremendous costs of building massive new plants. SMRs, by contrast, are small enough to be built in a factory and then hauled elsewhere to produce power. Advocates hope this will make them more cost-effective than the big reactors of today, offering an affordable, always-on complement to less-predictable renewables like wind and solar. According to some, they should also produce less radioactive waste than their predecessors. A Department of Energy-sponsored report estimated in 2014 that the US nuclear industry would produce 94 percent less fuel waste if big, old reactors were replaced with new smaller ones.

Krall was skeptical about that last part. “SMRs are generally being marketed as a solution—that maybe you don’t need a geological repository for them,” she says. So as a postdoc at Stanford, she and two prominent nuclear experts started digging through the patents, research papers, and license applications of two dozen proposed reactor designs, none of which have been built so far. Thousands of pages of redacted documents, a few public records requests, and a vast appendix full of calculations later, Krall, who is now a scientist with Sweden’s nuclear waste company, got an answer: By many measures, the SMR designs produce not less, but potentially much more waste: more than five times the spent fuel per unit of power, and as much as 35 times for other forms of waste. The research was published in the Proceedings of the National Academy of Sciences earlier this week.

Startups seeking licenses to build SMR designs have disputed the findings and say they’re prepared for whatever waste is generated while the US sorts out permanent disposal. “Five times a small number is still a really small number,” says John Kotek, who leads policy and public affairs at the Nuclear Energy Institute, the industry’s trade association.

But the authors say the “back-end” of the fuel cycle, which includes waste and decommissioning, should be a bigger factor in what they consider to be the precarious economics of the new reactors. “The point of this paper is to prompt a discussion,” says Allison Macfarlane, a former chair of the US Nuclear Regulatory Commission and a coauthor of the paper. “We can’t get to how much it is going to cost until we understand what we’re dealing with.”
