Volume and scarcity are different problems
The volume problem is real and tractable. Welders, electricians, mechanical fitters, project controls staff, quality engineers, planners: these are needed in large numbers, the training routes exist, and with enough order book visibility the supply chain will invest in producing them. It is a question of money, time and demand confidence. Difficult, but a known kind of difficult.
The scarcity problem is different. Some nuclear disciplines are held by populations numbering in the dozens or low hundreds nationally. Criticality safety. Probabilistic safety assessment at the level required to defend a submission. Severe accident analysis. Fault studies for a specific reactor type. Radiological protection for non-routine operations. Nuclear-grade structural integrity assessment. Licensing strategy for a novel design.
For these, the national stock is small enough that a single large programme can absorb a meaningful fraction of it. When that happens, the people do not appear from somewhere else; they move from one employer to another, and the sector’s aggregate capability is unchanged. The recruitment market for these disciplines is close to zero-sum.
Why the stock does not grow quickly
Three reasons, and none of them yields to a recruitment campaign.
The first is the development time. Competence in these disciplines is built through supervised work on real submissions over years, not through qualifications. A graduate entering criticality safety today is perhaps eight to twelve years from being able to lead a significant assessment independently. That timescale is not compressible by much, because the thing being developed is calibrated judgement about consequence, and judgement develops at the speed of experience.
The second is that development requires practitioners. Someone has to supervise, review, correct and sign. The only people who can do that are the scarce people themselves, so developing the next generation consumes the capacity of the current one. Organisations under delivery pressure routinely sacrifice the development to meet the deadline, which is rational each time and corrosive cumulatively.
The third is demographics. Significant parts of the UK expert population entered the industry during the last build programme and are now in the final decade of their careers. The retirement curve is steep and it is known, and it has been known for twenty years.
What this means for a programme
Several practical consequences follow for anyone planning work that depends on scarce disciplines.
Specialist availability is a schedule driver and should be modelled as one. A programme plan that assumes specialist input is available on request is not a plan. The scarce resource should appear in the schedule with the same rigour as a long-lead forging.
Early engagement is worth more than it costs. The same specialist input delivered during optioneering prevents considerably more rework than it does at submission. Because the resource is constrained, where it is spent matters more than how much of it is bought.
Sequencing across a portfolio matters. Two submissions needing the same discipline in the same quarter is a self-inflicted constraint. Looking across the programme and moving one by a few months is usually possible and usually cheaper than the alternative.
Buying capability does not create it. When a programme recruits aggressively in a scarce discipline, it has moved the constraint rather than removed it, and it may have moved it onto a regulator, a supplier or a partner whose delay then returns to the programme.
What actually helps
At the organisational level: protect development time formally rather than aspirationally, by funding it as a deliverable with a named output. Document method so that less experienced people can produce work the expert reviews rather than writes. Keep scarce people doing scarce work, which means resourcing the administrative and coordination load around them properly.
At the sector level: the things that work are shared development programmes, secondment arrangements that move people between organisations without losing them, and sustained order books that justify investment in people whose payback period is a decade. All of these require cooperation between organisations that are also competing, which is why they are discussed more often than they are implemented.
At the individual level, the most underused option is retention of experience past the conventional retirement point in reviewing, mentoring and assurance roles rather than delivery ones. The capacity is real, the appetite is often there, and the barriers are usually administrative.
The uncomfortable conclusion
For scarce nuclear disciplines there is no recruitment solution available on programme timescales. There is a development solution available on decade timescales, and a sequencing and leverage solution available now. Programmes that plan on the first one will discover the problem late. Programmes that plan on the second and third will get further with the people who actually exist.
NCL holds relationships with a large network of senior nuclear specialists, many of whom work confidentially, and we help clients plan around the disciplines that are genuinely constrained. Get in touch to discuss a specific requirement.
