Vo-Tech designs and manufactures engineered training mockups that replicate reactor components, valve assemblies, and specialty equipment with full operational fidelity. Built for procedure validation, crew training, and tool qualification, each mockup gives nuclear and industrial customers a controlled environment to prepare critical work — improving outage performance, reducing field exposure, and increasing first-pass success at the work face.
Vo-Tech Training Mockups are engineered physical reproductions of reactor components, valve assemblies, piping systems, and specialty equipment — built to replicate the geometry, mechanical behavior, and tooling interfaces of the real plant. Each mockup gives operators, supervisors, and procedure authors a safe, controlled, and repeatable environment to train on critical evolutions before they’re performed at the work face.
The work shown across Vo-Tech’s mockup catalog includes vertical motor and pump training assemblies with full instructor stations, RHR and other valve cutaway models with operational internal geometry, reactor head hole-cleaning machine training rigs, and transparent functional mockups that expose mechanism internals for instructional clarity. Every project is engineered to the customer’s procedure, the customer’s tooling, and the customer’s training environment — not adapted from a generic catalog model.
Outage success is determined in the months before the outage starts. Crews who have already performed an evolution in a controlled environment work faster, make fewer errors, accumulate less dose, and recover from unexpected conditions more reliably than crews seeing the work for the first time at the cavity floor. Engineered mockups move that learning curve out of the radiation field and into the training facility, with measurable returns:
Full-scale reproductions of reactor heads, valve assemblies, pump housings, and motor stands — built with operationally accurate stud geometry, sealing surfaces, mounting interfaces, and clearance constraints. Sized and configured for the customer’s training facility and integrated with platforms, instructor stations, and tool storage as required.
Models with strategically removed sections that expose internal geometry — valve internals, pump impellers, drive mechanisms, and component cross-sections. Cutaway mockups are essential for classroom training, supervisor walk-throughs, and visual learners; they communicate operating principles in seconds that prose and drawings struggle to convey.
Mockups with operating internal mechanisms — moving stems, rotating drives, working linkages — that respond to operator inputs the same way the real component does. Optional transparent housings expose mechanism behavior during operation. Instrumented variants capture force, torque, position, or rotation data for training feedback and procedure validation.
Purpose-built mockups for proving out specific outage tools, including reactor head hole-cleaning machines, nut runners, line boring systems, and custom tooling. Tool qualification rigs let manufacturers and host plants validate operational performance against representative geometry before the tool is deployed in a radiation field.
Integrated training environments combining the mockup with platforms, handrails, instructor stations, control consoles, and lighting — turning a component reproduction into a complete training facility ready for crew rotation.
Every Vo-Tech Training Mockup is designed, manufactured, and validated at the company’s Crystal Lake, Illinois facility — the same shop that builds Vo-Tech’s nuclear outage tooling and precision machining products. This single-source approach eliminates the integration risk that comes when mockups, procedures, and tooling are sourced from separate vendors. The shop that builds the tool builds the mockup it is qualified on.
Vo-Tech Training Mockups are produced under the company’s quality and regulatory framework:
Every Training Mockup is engineered and built to the customer’s specification. Project scope ranges from single-component cutaway models to multi-mockup training facility programs supporting complete outage curricula.
