庆祝 Holtec 三十周年重大创新

来源:www.gulfoilandgas.com 2024 年 11 月 13 日,地点:北美

三十年前,即 1994 年,Holtec International 向 USNRC 提交了第一份认证申请,以认证干式储存和运输容器。如今,Holtec 已向 USNRC 提交了 16 份与乏燃料储存和运输相关的申请,并已获得数十份证书修订,以满足客户的需求。在全球范围内,Holtec 的储存和运输系统及储存设施已获得 14 项认证。作为安全储存和运输废核燃料和高浓度非裂变废物的全球领导者,我们的创新技术提高了人类健康和安全以及环境保护。

在本期《Holtec 亮点》中,我们回顾了公司在干式储存和运输领域深耕三十年的历史,该项目从 1994 年的 20 名员工发展到今天的 800 多名员工。这些专家已向全球 149 个核电机组交付了(在大多数情况下)完整的交钥匙项目,这些核电机组分布在五大洲的 15 个国家/地区。在此期间,53 个站点的近 2,200 个存储系统已装载完毕,将近 110,000 个 PWR 和 BWR 燃料组件放入双用途容器和多用途罐 (MPC) 中。我们已获得美国专利局颁发的 200 多项关于废核燃料管理各个方面的创新专利,以及来自海外机构颁发的更多专利。这些发明证明了 Holtec 在塑造行业最先进的废燃料管理系统和策略发展方面所发挥的影响力。事实上,Holtec 是 90 年代中期第一家实现并获得 DOE 多用途罐 (MPC-68、MPC-24 和 MPC-32) 和双用途容器 (HI-STAR 100) 愿景的公司。在接下来的三十年里,我们不断涌现创新,这些创新不胜枚举,无法在本新闻简报中一一列举,但可以通过访问我们的网站了解。

本周,超过 80 名代表参加了在田纳西州纳什维尔举行的 Holtec 用户组 (HUG) 秋季会议 [见上图]。HUG 会议为 Holtec 干式储存系统用户提供了一个论坛,让他们聚集在一起讨论设计、许可、质量保证、制造和运营改进、问题、挑战、经验教训和最佳实践。如今,HUG 已有 26 年历史,已成为核工业中最大的干式储存桶用户组。


下面,我们重点介绍五个代表性案例,以说明 Holtec 的创新对全球干式储存行业产生的开创性影响:
强制氦脱水 (FHD) 设备 (2002):FHD 可以对严重浸水的燃料进行脱水。FHD 解决了干燥切尔诺贝利微毛细管缺陷 RBMK 反应堆燃料的挑战,甚至其反应堆供应商也无法解决这一问题!如今,超过 30 个核电机组依赖这项技术。HI
-STORM UMAX 发热废燃料地下储存 (2008):这项变革性技术使核材料的储存远离极端环境和人为事件的影响。Holtec 在新墨西哥州获得部署许可的综合临时储存设施 (2023) 将使用这项技术;加利福尼亚州和密苏里州的现场储存设施目前正在使用这项技术。
Metamic-HT 中子吸收剂 (2008):Metamic-HT 经美国核管理委员会授权,是一种纳米技术材料,可模拟硼化不锈钢的结构强度,但导热能力高出 10 倍,硼含量也高出 10 倍。我们位于俄亥俄州奥维尔的 300,000 平方英尺现代化制造工厂生产 Metamic-HT,全球几乎所有 Holtec 工厂都在使用这种材料。

超强屏蔽、无通风 MPC 存储外包装 (2023):经 USNRC 授权,这款基于 Holtec METCON™ 技术的外包装非常适合沿海地区,因为在海洋环境中,MPC 不锈钢外壳的应力腐蚀开裂是一个值得关注的问题。
扩展 HI-STORM 系统(将于 2025 年推出):我们的最新创新将在每个容器中以垂直抗震稳定堆栈的形式存储两个装载的 MPC,从而使现有或新存储垫的存储容量翻倍,目前正在接受 USNRC 的审查。预计它将于 2025 年投入部署。这项创新对于考虑长期(即 80 年)使用寿命但现有存储垫已填满而因可用土地短缺而受阻的场地来说将非常有价值。

本周,在向 HUG 代表团发表讲话时,Holtec 长期任职的首席执行官 Kris Singh 博士表示,“我们很自豪在过去 30 年中在废燃料储存和运输系统的安全性、保障性和性能方面取得了重大进展,我们相信这有助于提高公众对新核能的接受度和热情,将其作为解决环境中二氧化碳不断积累的有力解决方案。”

Celebrating Thirty Years of Holtec’s Consequential Innovations

Source: www.gulfoilandgas.com 11/13/2024, Location: North America

Thirty years ago, in 1994, Holtec International opened its first docket with the USNRC and submitted its first license application to certify a dry storage and transport cask. Today, Holtec has 16 dockets with the USNRC related to spent fuel storage and transportation and has secured dozens of certificate amendments that serve our clients’ needs. Globally, Holtec holds 14 certifications for its storage and transport systems and storage facilities. As the world leader in safely storing and transporting used nuclear fuel and high level non-fissile waste, our innovative technologies have increased human health and safety and protection of the environment.

In this issue of Holtec Highlights, we mark three decades of our corporate immersion in dry storage and transport which has experienced growth of the program from a slender staff of 20 in 1994 to over 800 personnel today. These experts have delivered (in most cases) complete turnkey projects to 149 nuclear units worldwide that are based in 15 countries on five continents. In this period, nearly 2,200 storage systems at 53 sites have been loaded, placing almost 110,000 PWR and BWR fuel assemblies in dual purpose casks and Multi-Purpose Canisters (MPCs). We have obtained over 200 patents granted on innovations in various aspects of used nuclear fuel management issued by the US Patent Office and many more issued by overseas authorities. This large body of inventions speaks to the impact that Holtec has had in shaping the evolution of the industry’s state-of-the-art used fuel management systems and strategies. In fact, Holtec became the first company in the mid-90s to actualize and license DOE’s vision of the multi-purpose canister (MPC-68, MPC-24, and MPC-32) and the dual-purpose cask (HI-STAR 100). A continuous stream of innovations has followed in the ensuing three decades which are too numerous to recount in this news bulletin but can be accessed by consulting our website here.

Over eighty delegates are attending the autumn meeting of the Holtec User Group (HUG) in Nashville, TN, this week [see photo above]. HUG meetings provide the forum for Holtec dry storage system users to gather and discuss design, licensing, QA, manufacturing, and operational improvements, issues, challenges, lessons learned, and best practices. Now 26 years old, HUG has become the largest dry cask users group in the nuclear industry.


Below, we highlight five representative examples that illustrate the trailblazing impact of Holtec’s innovations on the global dry storage industry:
Forced Helium Dehydration (FHD) Equipment (2002): FHD makes it possible to demoisturize severely water-logged fuel. FHD met the challenge of drying Chernobyl’s micro-capillary defect-filled RBMK reactor fuel which even its reactor supplier was unable to solve! Today, over 30 nuclear units rely on this technology.
HI-STORM UMAX Below-Ground Storage of Heat-Emitting Used Fuel (2008): This transformative technology renders storage of nuclear material beyond the reach of extreme environmental and human events. Holtec’s consolidated interim storage facility licensed for deployment in New Mexico (2023) will use this technology; this technology is currently in use at on-site storage facilities in California and Missouri.
Metamic-HT Neutron Absorber (2008): Licensed by the USNRC, Metamic-HT is a nanotech-inspired material that emulates the structural strength of borated stainless steel but possesses 10 times greater heat conduction capacity and packs 10 times higher boron content. Our 300,000 sq./ft modern manufacturing plant in Orrville, Ohio manufactures Metamic-HT, which is being used in practically every Holtec site around the world.

Mega-Shielded, Unventilated MPC Storage Overpack (2023): Licensed by the USNRC, this incarnation of Holtec’s METCON™ technology-based overpack is ideal for coastal sites where stress corrosion cracking of the MPCs’ stainless exterior in marine environment is a concern.
Extended HI-STORM System (coming in 2025): Our latest innovation which will store two loaded MPCs in a vertical seismically stable stack in each cask, essentially doubling the storage capacity of existing or new storage pads, is undergoing USNRC review at this time. It is expected to be available for deployment in 2025. This innovation will be valuable for sites contemplating long (i.e., 80-year) service life but are hobbled by a shortage of useable land as their existing storage pads fill up.

Addressing the HUG delegation this week, Holtec’s long-serving CEO, Dr. Kris Singh stated, “We are proud to have made materially significant strides in the safety, security, and performance of used fuel storage and transport systems in the past three decades which we believe have helped grow public acceptance of and enthusiasm for new nuclear as a robust antidote to the unabated accumulation of carbon dioxide in the environment.”
