The Nuclear Waste Technical Review Board (NWTRB) has released a comprehensive and highly technical report on the Department of Energy's research efforts into high-burnup spent nuclear fuel. The NWTRB is an independent federal agency tasked with evaluating the technical and scientific validity of DOE activities related to managing and disposing of high-level radioactive waste and spent nuclear fuel.

The NWTRB report to the U.S. Congress and the secretary of energy, Evaluation of the Department of Energy’s Research Program to Examine the Performance of Commercial High Burnup Spent Nuclear Fuel During Extended Storage and Transportation, was posted to the board’s website on August 2. It is a product of a multi-year effort during which the NWTRB reviewed the DOE’s research activities into the performance of high-burnup spent nuclear fuel (SNF) in extended storage and transportation conditions.

Hoping to drive progress on the safe storage, transportation, and disposal of spent nuclear fuel across the country, Reps. Mike Levin (D., Calif.) and Rodney Davis (R., Ill.) have formed the Spent Nuclear Fuel Solutions Caucus in the U.S. House of Representatives.

According to Levin and Davis, the bipartisan caucus seeks to address the challenges associated with stranded commercial spent fuel across the country and serve as a forum where House members can come together to make headway on the issue, regardless of whether or not they have a preferred solution.

In announcing the formation of the caucus on July 21, Levin and Davis said that the current system of spent nuclear fuel storage is not sustainable, particularly for sites that no longer have operating reactors and could be redeveloped for other beneficial uses. They added that it is also a violation of the promise, codified by law, that the federal government would take title to the waste in return for ratepayers’ contributions to the Nuclear Waste Fund.

The DOE recently completed startup testing on the uninterruptable electrical power system for Hanford’s Low-Activity Waste Facility.

Department of Energy workers recently finished startup testing of a battery-powered backup electrical system for the Low-Activity Waste (LAW) Facility at the Hanford Site near Richland, Wash. According to the DOE’s Office of Environmental Management (EM), the uninterruptable electrical power system is vital to safeguarding the facility, part of Hanford’s Waste Treatment and Immobilization Plant, in the unlikely event of a temporary power loss to the plant.

Holtec International is increasing the production of its HI-STAR casks for storing and transporting spent nuclear fuel following recent regulatory approvals and new orders in Europe. Earlier this month the company was awarded a contract by Spain’s waste management organization Enresa for 10 HI-STAR 150 casks, and Holtec is currently in the advanced stages of production of two HI-STAR 180D casks destined for the Doel nuclear power plant in Belgium, with additional orders pending.

The casks are being produced at Holtec’s manufacturing facilities in New Jersey, Pennsylvania, and Ohio.

Spain: Enresa initially awarded Holtec a contract in 2017 for the design, engineering, licensing, and manufacturing of five HI-STAR 150 casks for the Cofrentes nuclear power plant near Valencia. The Spanish Nuclear Safety Council signed off on the HI-STAR 150 design for storage in April of this year, and on May 23, Spain’s Ministry of Ecological Transition and the Demographic Challenge granted a license for the cask, which is designed to store up to 52 boiling water reactor spent fuel assemblies, including damaged fuel assemblies.

The amount of salt mined so far from Panel 8 at the Department of Energy’s Waste Isolation Pilot Plant (WIPP) is a lot. The DOE’s Office of Environmental Management (EM) compared the amount to the weight of more than 46,000 Ford F-150s, about 16,000 African bush elephants, nearly 510 Boeing 747s, two Titanics, or enough to coat the rims of 3.6 million margarita glasses.

Miners working 2,150 feet underground extract the salt using grinders called continuous miner machines to create space to place defense-related transuranic (TRU) waste.

With WIPP’s Panel 8 scheduled for completion in a little more than half a year, crews recently crossed the 100,000-tons-mined threshold and, as of mid-June, are at 105,000 tons removed from the panel.
