A proposed interim(中間・暫定) storage facility in a remote area(辺境) of New Mexico that has been seen as a possible destination(目的地＞送り先) to take commercial nuclear waste from sites such as the San Onofre Nuclear Generating Station suffered a major setback(セットバック。元々の意味は後退・抑制。そのまんまかｗ) over the weekend(週末に atは英，onは米だそうな。overでも云えてこの場合は"期間を表す前置詞"だそうな。週末の間にってニュアンスらしい。https://kiwi-english.net/22098) after the state’s governor came out against the project.
ホルテック社は、2015年8月3日に、許認可申請の意向通知をNRCに提出?してNRCとの事前協議を進めてきたほか、採用する地下貯蔵方式のHI-STORM UMAX（Holtec International STORage Module Underground MAXimum securityの頭字語）システムについて、米国で使用中のすべての乾式貯蔵キャスクの受入れ・貯蔵が可能となるよう、適合承認（CoC）の変更申請を2016年8月30日にNRCに提出している?。
(Reuters) - U.S. energy company Exelon Corp said Wednesday it will shut the last reactor at the Three Mile Island power plant, site of the worst nuclear accident in U.S. history, on Sept. 30 due to legislative inaction on a nuclear subsidy bill in Pennsylvania.
“With only three legislative session days(議会開催日？) remaining in May and no action taken to advance(法案を提示する) House Bill(下院法案) 11 or Senate Bill(上院法案) 510(数字は何だ？？法案番号みたいなもの？), it is clear a state policy solution will not be enacted before June 1,” Exelon said in a release, referring to the proposed nuclear subsidy bills(原子力補助法案).
Exelon said it had to make a decision by June 1 to purchase fuel for the plant for its next operating cycle. The company announced in May 2017 that it would shut the 45-year-old reactor in 2019 without policy reform to support the plant.
Analysts at Height Capital Markets(ワシントンD.C.のファイナンシャル プランナー https://www.heightllc.com/) said in a report that the shutdown, which will come 40 years after the 1979 meltdown of another reactor at the plant, will increase pressure on Pennsylvania legislators to pass a nuclear subsidy bill in the autumn to protect the state’s remaining eight reactors from early closures.
In recent years, electricity prices have been depressed by cheap natural gas from shale fields(shale fields：頁岩部層 日本だとnatural gas from shale fieldsでシェールガスと云っちゃう？), including the Marcellus in Pennsylvania, and increased use of renewable power. This has made some nuclear plants uneconomical, and forced generators to shut several reactors over the past five years.
Several states, including New York, Illinois, Connecticut and New Jersey have already adopted nuclear subsidies to keep their reactors in service to help meet carbon reduction goals.
Lawmakers in Pennsylvania and Ohio are considering legislation, while officials in U.S. President Donald Trump’s administration have proposed programs to keep nuclear and coal plants operating longer.
In late April, Pennsylvania Governor Tom Wolf released a plan to reduce the state’s greenhouse gas emissions. To achieve those goals, Wolf recommended implementing policies (implementing actionで実行作業。実行政策？) to keep the state’s nuclear reactors in service. Nuclear plants do not emit carbon dioxide, one of the major causes of global warming.
Nuclear power plants generate 42 percent of Pennsylvania’s electricity and provide 93 percent of its zero-carbon power.
Elsewhere in Pennsylvania, Exelon operates two reactors at the Peach Bottom and two at Limerick, FirstEnergy Corp operates two reactors at Beaver Valley and Talen Energy owns two at Susquehanna.
FirstEnergy’s bankrupt FirstEnergy Solutions unit said it would shut Beaver Valley in 2021 unless the reactors receive some financial support from federal or state programs.
