Dry cask storage engineerSalary, qualifications, career path and hiring demand, 2026 edition
A dry cask storage engineer designs and licenses the systems that hold spent fuel once it leaves the pond. Sealed canisters inside concrete or steel overpacks, cooled by nothing but air moving past them, standing on a concrete pad for decades. No pumps, no power, no moving parts, and no opportunity to open them and check. This role requires expertise in dry cask storage specialist duties and compliance with Nuclear Regulatory Commission regulations, ensuring safe management of spent nuclear fuel in dry cask storage systems used by nuclear natural gas geothermal hydro power producers.
Dry cask storage engineers earn a median of around $126,000 in the United States and roughly £52,000–£68,000 at mid to senior level in the UK, rising past £103,000 for a principal. Licensing and loading specialists sit at the top, reflecting years of reviews industry operating experience and specialized nuclear or technical discipline expertise.
No licence required. What gates the work is thermal, structural and shielding competence plus the regulatory knowledge to licence a dry cask storage system, including familiarity with Nuclear Regulatory Commission regulations, development of detailed plans for spent fuel loading campaigns, and working across organizational boundaries within constellation clean energy center operations.

Six versions of the same job title
"Dry cask storage engineer" changes with the work: designing and licensing a system, supporting loading campaigns, or renewing licences for casks already loaded decades ago. Note fuel cycle and operating fleet lead together. Meter = relative hiring volume across TRX's 2026 desk activity.
Fuel handling & fuel cycle
Designing and licensing dry storage systems: canister and overpack design, thermal and shielding analysis, structural qualification, and the licensing submissions that permit their use. Holtec, Orano TN, NAC and equivalents.
Operating fleet
Supporting dry storage at operating stations: loading campaigns, pad expansion, system selection and the ongoing storage installation. US fleet.
Decommissioning & dismantling
Dry storage at decommissioning sites, where the entire inventory is transferred to casks and the storage installation frequently outlives everything else on site. US decommissioned sites, Magnox fleet.
Radioactive waste management
Long-term storage strategy and the interface with eventual disposal, since casks must be retrievable and their contents transportable.
Large new build
Planning dry storage provision for a new station, which will eventually be required even if not immediately. Hinkley Point C, Sizewell C.
New technology development
Storage systems for advanced reactor fuels, which differ in geometry, heat output and chemistry from the fuel current casks are designed for.

Licensing capability
Getting a storage system licensed, and renewing licences for systems already in service, is specialised regulatory engineering.
Loading campaign delivery
Campaigns are repeatable, schedule-driven programmes and experienced engineers are requested by name.
Extended storage and renewal
Many casks are approaching the end of their initial licence period, and renewal requires evidence nobody originally gathered.
Three ways in, and only one of them starts with a nuclear degree
Dry cask storage is entered from mechanical, structural or thermal engineering, and it converts well from transport packaging and pressure vessel work.
Graduate, United States
Four to eight years to senior, and the larger market.
Graduate, United Kingdom
Four to eight years.
Career changer
Twelve months to three years, a strong crossover.

Licence renewal is the emerging workload
The first dry storage systems were licensed for initial periods that are now expiring, and renewing them requires demonstrating that spent nuclear fuel and casks have performed as assumed over decades. Much of the supporting evidence was never gathered because nobody expected storage to last this long. That has created a substantial ageing management and renewal workload, distinct from designing new systems, and it is where a growing share of the discipline's effort now goes.
The US holds most of the industry operating experience
Dry storage became routine in the US decades before it did elsewhere, so the deepest design, licensing, and campaign experience sits with US vendors and utilities. As other countries face filling ponds and begin adopting dry cask storage, they are recruiting into a discipline where the experienced population is concentrated in one national market and its regulatory framework, which limits how directly that experience transfers. This includes knowledge of the Nuclear Regulatory Commission regulations and the station's DCS loading plan, which are critical for compliance in nuclear operations.
Adjacent and onward roles
Dry storage sits between spent fuel management and transport. These are the moves TRX sees most often.
Questions we get asked every week
How much does a dry cask storage engineer earn in 2026?
In the United States the market runs from about $78,000 for a graduate to $126,000 at the median, with principals past $196,000. In the UK it runs from £31,000–£39,000 for a graduate to £80,000–£103,000 for a principal. Licensing and loading campaign specialists sit at the top, and contract engineers bill £720–£950 a day outside IR35. The expected salary range reflects years of dry cask storage experience and technical nuclear users group standards.
Do you need a licence for dry cask storage engineering?
No. PE or CEng applies at senior grades and is expected for design responsibility. The practical differentiator is licensing knowledge: getting a storage system approved, and renewing approvals for systems already in service. This includes governance and oversight g functions and compliance with technical specifications.
Can you become a dry cask storage engineer without a nuclear background?
Yes. Transport packaging engineers transfer particularly well, since the analysis and regulatory framework overlap heavily, and pressure vessel and structural engineers convert on fundamentals. The nuclear-specific content is decay heat, shielding, criticality in the loading basket, and alara practices technical specification compliance, plus the fact that a sealed cask cannot practically be opened again. Engineering disciplines e.g chemistry, construction, computer science, civil structural electrical industrial mechanical are relevant backgrounds.
Is dry cask storage a good career in 2026?
Demand is strong and structural, because ponds continue to fill and licence renewal for early systems is creating substantial new workload. The honest caveat: the US market is far larger than the UK's, so opportunities and experience are concentrated there, and the regulatory framework does not transfer directly between countries. The role supports clean and reliable energy initiatives and involves spent fuel loading campaigns and review vendor performance trends.
What is the difference between dry cask storage and spent fuel management?
A spent fuel management engineer owns the inventory and strategy: where fuel is, how much capacity remains, criticality and thermal assessment across storage and the plan for moving it. A dry cask storage engineer designs and licenses the storage systems: canisters, overpacks, thermal and structural qualification and the loading operations. Put simply, one manages the fuel and the other engineers what holds it. Spent fuel managers decide that fuel needs to move to dry storage; cask engineers make sure there is a licensed system to move it into. This includes coordination with the spent fuel working group and fuel working group.
Which dry storage skills are most in demand in 2026?
Licensing capability leads, because both new systems and renewals depend on it and the regulatory work is specialised. Close behind is licence renewal and ageing management and loading campaign experience. Thermal analysis, structural analysis and criticality in loading are the near-universal hard filters. Familiarity with nuclear energy institute standards and constellation reactor services experience also enhance candidacy.
We only recruit in nuclear. That is the whole point.
