Holtec International’s SMR-160 is a pressurized light-water thermal spectrum reactor that relies on natural circulation, thereby eliminating the need for reactor coolant pumps during normal operation. The reference design incorporates a lower pressure conventional steam turbine and wet cooling via a tube-and-shell condenser coupled with forced-draft cooling towers. Optionally, the plant can use dry cooling via Holtec’s HI-KOOL air-cooled condenser.

New York Attorney General Letitia James filed a lawsuit on behalf of the State of New York against the Nuclear Regulatory Commission over the sale of the Indian Point nuclear power plant to subsidiaries of Holtec International for decommissioning.

Filed in the U.S. Court of Appeals for the District of Columbia Circuit on January 22, the suit challenges the NRC’s denial of New York’s petition for a hearing regarding the transfer of Indian Point’s licenses from owner Entergy to Holtec, as well as the NRC’s initial approval of the license transfer. The NRC approved the transfer in November 2020 while challenges from the state and other groups were still being adjudicated. The NRC issued its order denying New York’s petition to intervene on January 15.

The transfer of ownership of the plant from Entergy to Holtec is targeted to occur after Indian Point-3 shuts down in April 2021. Indian Point-2 permanently ceased operations in April 2020, and Indian Point-1 has been shut down since 1974. The pressurized-water reactors are located in Buchanan, N.Y., approximately 24 miles north of New York City.

Holtec SMR could be built at Oyster Creek site

January 11, 2021, 3:00PMANS News

The site of the Oyster Creek Nuclear Generating Station in Lacey Township, N.J., could be the location for Holtec International’s SMR-160 small modular reactor, according to an AP News story published last week.

ARDP investment: Holtec received $147.5 million in Advanced Reactor Demonstration Program funding to demonstrate its SMR design. Company spokesperson Joe Delmar said, “As part of our application to the Department of Energy for its advanced reactor demonstration program, we expressed interest in possibly locating an SMR-160 small modular reactor at the Oyster Creek decommissioning site in the future. This concept is only preliminary and something we would likely discuss with Lacey Township and the community if plans to locate (the reactor) at Oyster Creek evolve.”

Five advanced reactor designs get DOE risk reduction funding

December 16, 2020, 3:00PMNuclear News

The Department of Energy today announced $30 million in initial fiscal year 2020 funding—with the expectation of more over the next seven years—for five companies selected for risk reduction for future demonstration projects. The chosen reactor designs from Kairos Power, Westinghouse, BWX Technologies, Holtec, and Southern Company collectively represent a range of coolants, fuel forms, and sizes—from tiny microreactors to a molten salt reactor topping 1,000 MWe. They were selected for cost-shared partnerships under the Office of Nuclear Energy’s Advanced Reactor Demonstration Program (ARDP) through a funding opportunity announcement issued in May 2020.

“All of these projects will put the U.S. on an accelerated timeline to domestically and globally deploy advanced nuclear reactors that will enhance safety and be affordable to construct and operate,” said Energy Secretary Dan Brouillette. “Taking leadership in advanced technology is so important to the country’s future, because nuclear energy plays such a key role in our clean energy strategy.”

The transfer of the Indian Point nuclear power plant licenses from Entergy to Holtec International, as owner, and Holtec Decommissioning International (HDI), as decommissioning operator, has been approved by the Nuclear Regulatory Commission. The license transfers follow the transfer of the licenses of the Oyster Creek nuclear plant from Exelon and the Pilgrim plant from Entergy to Holtec in mid-2019. As with the Oyster Creek and Pilgrim plants, Holtec and HDI intend to expedite the decommissioning and dismantling of Indian Point.

Indian Point’s three pressurized water reactors are located in Buchanan, N.Y., approximately 24 miles north of New York City. Units 1 and 2 have been permanently shut down, in 1974 and 2020, respectively, and Unit 3 is scheduled to be shut down in April 2021. The license transfer also includes the plant’s independent spent fuel storage installation (ISFSI).

The Nuclear Regulatory Commission has denied a request by the antinuclear group Pilgrim Watch for a hearing in the transfer of the Pilgrim nuclear power plant’s license from Entergy to a subsidiary of Holtec International for decommissioning. The NRC commissioners issued the order denying Pilgrim Watch’s petition to intervene and request a hearing on November 12.

Pilgrim Watch submitted its petition against the transfer of Pilgrim’s license from Entergy to Holtec Decommissioning International in February 2019. The NRC staff, however, approved the transfer in August 2019, while the petition was still under review. NRC regulations allow staff to approve a license transfer under the condition that the commissioners may later move to “rescind, modify, or condition the approved transfer based on the outcome of any post-effectiveness hearing on the license transfer application.”

A separate petition against the license transfer submitted by the state of Massachusetts was withdrawn in June, following a settlement agreement between the state and Holtec.

Pilgrim permanently ceased operations in May 2019. Holtec plans to decommission the plant (with the exception of the independent spent fuel storage installation) on an eight-year schedule to permit partial site release by the NRC.

Holtec International announced yesterday a drive to secure Nuclear Regulatory Commission design certification of the company’s SMR-160 small modular reactor on an accelerated schedule.

According to the announcement, Holtec met with NRC officials and staff on September 30 to present a licensing roadmap that charts what the company referred to as a “seamless progression from [10 CFR Part 50] to [10 CFR Part 52] and a licensing topical report submittal schedule to support an accelerated availability plan for our global customers.”

The first planned submittal, scheduled to occur within the next few weeks, is a topical report covering the SMR-160’s essential safety features: the Passive Core Cooling System (PCCS) and Passive Containment Heat Removal System (PCHR). These systems, Holtec said, “undergird the SMR’s guaranteed safety under the various operational occurrences and hypothetical accidents that may afflict the plant.”

The submittal also aims to demonstrate that the PCCS and PCHR comply with the NRC’s General Design Criteria (Part 50, Appendix A), “an important enabler to expedite licensing efforts,” according to Holtec.

Abbott

In a letter sent to President Trump on September 30, Texas Gov. Greg Abbott expressed his opposition to two proposed consolidated interim storage facilities for spent nuclear fuel that are currently under review by the Nuclear Regulatory Commission. Abbott is opposing Interim Storage Partner’s (ISP) interim storage facility in West Texas and Holtec International’s planned facility in New Mexico, near the Texas border, claiming that the facilities will put U.S. energy security at risk by being sited within the oil-producing region of the Permian Basin.

Abbott also said that he was opposed to increasing the amount of radioactive waste permitted to be disposed of in Texas without state approval. In April 2019, Abbott wrote to the Department of Energy and the NRC expressing his objections to federal actions that could allow Waste Control Specialists (WCS) to accept greater-than-Class C waste at its disposal site in Andrews County, Texas. ISP is a joint venture of WCS and Orano USA.
