A planned Nuclear Regulatory Commission inspection of the dry cask storage web page, which includes transferring the remaining invested nuclear gas into canisters, at the decommissioning Oyster Creek Nuclear Making Station in Lacey Township observed no considerable security issues.
NRC inspectors had been on hand the 7 days of Dec. 14-19 for the loading of the to start with of 33 spent casks at the site’s unbiased put in fuel storage installation pad. The loading of the cask was suspended on Dec. 19 because of to an challenge with the cask ports, in accordance to the NRC’s inspection report. The do the job remained halted for two weeks to allow for for the vacations and for the resolution of the difficulty.
“Review of records, stories, and strategies ongoing right up until completion of the inspection pursuits coinciding with completion of the leak test was first attempted,” the NRC stated in its inspection report.
Furthermore, the inspectors reviewed planned activities for the lengthy-time period operation and checking of the dry cask storage web site and watched gasoline assemblies staying loaded into the multi-intent canisters.
Prior to that, inspectors were on hand for the onsite fabrication of parts and development of an impartial put in fuel storage set up, according to the NRC’s report. The scope of that inspection integrated examining and observing plant things to do to determine if development adhered to good quality assurance strategies.
Oyster Creek, a boiling h2o reactor driven by Common Electrical, forever ceased functions on Sept. 17, 2018. Holtec Decommissioning International, a subsidiary of Holtec Intercontinental, assumed ownership and licensee status of Oyster Creek in June 2019 after a nearly 10-month application overview by the NRC. The plant experienced beforehand been owned by Exelon Generation, section of the Exelon Corp. nuclear fleet.
Less than its decommissioning options, HDI moved made use of fuel from its put in the spent nuclear pool to an onsite dry storage facility after the nuclear waste cooled for 2½ a long time. All of Oyster Creek’s employed nuclear gasoline was moved to its spent gas pool in September 2018, about a 7 days after the plant ceased functions for superior.
The NRC has approved the going of used gasoline to dry storage as early as 3 yrs after it was moved to the expended gas pool. The business common, in accordance to the NRC, is 10 many years.
Decommissioning of the shuttered nuclear plant is anticipated to be accomplished by 2025. Holtec officials will talk to for a partial site release, with the only exception becoming the onsite dry cask storage pad. Dry storage need to remain at the internet site until eventually the federal govt takes possession of it.
Though the NRC is even now thinking of two apps for separate federal expended nuclear fuel repositories, its transportation readiness evaluation is predicted to be readily available to the community no afterwards than Could. Just one of the internet sites, dependent in New Mexico, is proposed by Holtec Intercontinental.
Holtec has petitioned the NRC to create and run phase a person of the interim repository on about 1,040 acres of land in Lea County, N.M. The land is owned by Eddy-Lea Vitality Alliance, a community system developed by means of a joint-powers arrangement concerning Eddy and Lea counties as perfectly as the metropolitan areas of Carlsbad and Hobbs, located in southeast New Mexico.
In its license software for the facility, Holtec is searching for authorization to retail store 5,000 metric tons of uranium (MTUs) in around 500 invested nuclear gas canisters less than a 40-yr license. However, NRC employees mentioned in the Oct. 9 consolidated response to listening to requests on the repository that specific canisters fluctuate in capability. The 500 canisters proposed by Holtec have the probable to keep up to 8,680 MTUs from commercial nuclear reactors as effectively as a little quantity of invested mixed-oxide gas.
If the NRC difficulties the requested license, Holtec expects to subsequently talk to for added amendments to the first license to increase the storage potential of the facility. Under its proposal, the business would expand the facility in 19 subsequent phases, every single for an further 500 canisters, to be accomplished in excess of the class of 20 years.
