The Department of Energy earlier this year approved part one of a loan application from Holtec International for small modular reactor construction and invited the firm to apply for a loan to help build four of its SMR-160 units and grow its manufacturing capacity to produce the first wave of SMRs.

Holtec International and Hyundai Engineering & Construction have signed an agreement to cooperate in the area of nuclear plant decontamination and decommissioning.

Under the teaming agreement, Hyundai E&C will participate in D&D activities at Holtec-owned decommissioning sites in the United States to build its capabilities and experience in preparation for decommissioning projects in South Korea, which will be undertaken by the two companies. The agreement also provides for the two companies to further expand their cooperation internationally.

Holtec International said its manufacturing specialists continue to bring forth new welding and weld examination technologies. The company recently highlighted three “landmark achievements” that are transforming its manufacturing program.

In addition to manufacturing spent nuclear fuel storage and transportation casks, Holtec provides products and services to the nuclear industry, including nondestructive examination of in-service reactor components. The company is also developing its own small modular reactor, the SMR-160.

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.

Holtec steps up efforts for SMR design certification

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.
