The Nuclear Regulatory Commission has denied “without prejudice” Oklo Power’s application to build and operate its Aurora microreactor in Idaho, the agency announced yesterday. The denial, according to the NRC, is due to the California-based firm’s failure to provide sufficient information on several crucial topics regarding the Aurora design.

Oklo plans to fuel its demonstration microreactor with high-assay low-enriched uranium (HALEU). To secure a source of HALEU for its nth-of-a-kind microreactor, Oklo has signed a nonbinding letter of intent with Centrus Energy to cooperate on the deployment of a HALEU production facility.

The Nuclear Regulatory Commission has begun its review of GE Hitachi’s application to renew the license of its Morris Operation, the spent nuclear fuel storage facility in Grundy County, Ill. Notice of the 20-year license renewal application, along with an opportunity to request a hearing or petition for leave to intervene by August 30 was published in the June 30 Federal Register.

The Nuclear Regulatory Commission has rejected a petition by Three Mile Island Alert (TMIA) challenging Exelon’s request to revise its site emergency plan for the closed Three Mile Island nuclear power plant in Pennsylvania. Exelon submitted a request to the NRC to amend its TMI-1 license to reflect the reduced risks of the defueled reactor, which was permanently shut down in September 2019.
In an order issued on October 8, the NRC commissioners upheld a decision by an NRC Atomic Safety and Licensing Board denying TMIA’s petition to intervene and request a hearing in the license amendment request. That decision, issued on January 23, 2020, found that the antinuclear group had not established standing in the case and that its contentions were inadmissible.

The Nuclear Regulatory Commission is amending its regulations for the licensing, inspection, special projects, and annual fees that it will charge applicants and licensees for fiscal year 2020. The FY 2020 final fee rule, published in the June 19 Federal Register, includes fees required by law to recover approximately 90 percent of the NRC’s annual budget authority. A proposed rule was published for public comment on February 18 of this year, with a March 19 due date. The final rule goes into effect on August 18.

The Nuclear Regulatory Commission on March 24 relicensed the only uranium conversion plant in the United States, Honeywell International’s Metropolis Works.
Metropolis Works can now operate until March 24, 2060, potentially logging operations for over a century. Built in 1958 to produce uranium hexafluoride (UF6) for the U.S. government, Metropolis Works began selling UF6 on the commercial market in 1968.

The year 1971 saw a continuation of the general trend of rising capital costs for all types of power plants, described by the U.S. Atomic Energy Commission (AEC) in its publication for 1971 as having "risen rather rapidly." According to the AEC, the aggregate major causes for the increases in costs specific to nuclear electric power plants were as follows, with author's analysis accompanying each:

The process for renewing research and test reactor (RTR) licenses in the United States has been subject to lengthy delays and periodic backlogs since the early 1980s. Despite the apparent time invested in improvement efforts, the process does not seem to be getting better very fast. The difficulty, schedule uncertainty, and cost of renewing research reactor licenses adds to the burden of owning and operating research reactors. The scale of the challenge may contribute to regrettable institutional decisions that maintaining operable facilities is not worth the trouble.

I received an email this morning (in the midst of my daily avalanche of promotional emails) with a link to a brief story about uprating of nuclear plants worldwide (in other words, increasing the power output of an already-built plant)-what had been done, how many were planned, and so forth. I wondered to myself just how many nuclear plants in the United States had been uprated, and when they started-and given the recent hullabaloo over the recent U.S. Environmental Protection Agency CO2 emission policy, it seems like (in addition to discussing small modular reactors) we might also want to toss the uprate card back on the table. Instead of flat or only slightly rising demand for electricity, we may face a steady lowering of generating capacity as plants that are high CO2 emitters (and thus violators) get shut down. Sure, renewables will play a part, and so will increased efficiency, but having more power is better than having less, or too little. I found no quick and easy reference for the kind of analysis I wanted, so I took a little time and did it myself.

Shortly after 11 a.m. on Tuesday, May 7, 2013, the operators at Dominion Resources' Kewaunee nuclear power plant opened its output breaker, disconnecting the turbine generator from the grid for the last time after just under 40 years of operation. Shutdown of the reactor followed, and the plant entered what for some is an uncertain (even if pre-ordained) future-a long-term storage period, followed eventually after many years by the complete dismantling and removal of the plant.

The Davis-Besse nuclear power plant, operated by FirstEnergy Nuclear Operating Company, is located on the shores of Lake Erie about 20 miles east of Toledo, Ohio. The 908-MWe pressurized water reactor came online on July 31, 1978.

As I discussed in a June 20 ANS Nuclear Cafe post, a federal appeals court rejected the Nuclear Regulatory Commission's new nuclear Waste Confidence rule, and ordered the NRC to perform a more thorough evaluation that addresses potential risks and health and environmental impacts of very long term storage of nuclear waste at nuclear sites (until a final disposal option is developed).

Plymouth, Massachusetts, "America's Home Town," is the place where the pilgrims landed, and is also the home of the Pilgrim nuclear power plant. On March 29, a forum was held in Plymouth to discuss a non-binding ballot question for the town election in May. The question is whether or not to freeze the plant's relicensing process until all the Fukushima fixes are completed.

The U.S. Nuclear Regulatory Commission on March 30 voted to clear the way for its Office of New Reactors to issue two licenses for two new AP1000 reactors at the V.C. Summer site in Parr, S.C. This marks the NRC's second approval of nuclear units to be built in the United States in two months. In February, the NRC approved a license for Atlanta-based Southern Company's Vogtle project, in Waynesboro, Ga. The NRC had not issued any new reactor licenses since 1978.
