Where the lift
answers to the CNSC.
A nuclear lift is the most scrutinized pick in heavy industry — a steam generator replaced, a reactor component handled inside a radiation zone, a turbine set in the hall, all under CNSC oversight, an ALARA dose budget, and a security regime. The outage clock runs at over a million dollars a day. We engineer that lift — load-path-first, radiation-zone-aware, sealed to the licensee's quality + security program before mobilization. The licensee runs the reactor ; we get the heavy thing into place.

Radiation-zone lifts without a sealed plan in hand
Six exposures under nuclear oversight.
Nuclear lifts carry the highest consequence in the portfolio — a radiation zone, a regulator that reviews everything, a dose budget, and an outage clock. The exposures below are what the sealed lift plan exists to control. Every Maxor deliverable in this vertical addresses them explicitly.
Nuclear-safety consequence
A dropped load near safety-related systems isn't an equipment problem — it's a nuclear-safety event with a regulatory, public, and licensing tail. The lift plan controls the pick that the plant's safety case cannot absorb failing.
Radiation zone + ALARA
Lifts inside controlled areas accumulate dose. As-Low-As-Reasonably-Achievable means the lift is planned for minimum time-in-field — staged, rehearsed, and sequenced so the crew's exposure is engineered down, not discovered on the floor.
CNSC regulatory scrutiny
The Canadian Nuclear Safety Commission reviews the work. A poorly-engineered lift becomes a licensing-file item that follows the station. Sealed deliverables, traceable to the licensee's management system — every time.
Outage overrun cost
A nuclear outage burns $1 M+ per day, and the critical path is unforgiving. A lift that slips its slot in the outage sequence pushes the return-to-service. The lift campaign is engineered against the fixed outage window.
Security clearance + access
Nuclear sites operate under federal security regimes. Crane mobilization, crew clearance, and equipment staging run through the station's security program — documented in the lift plan from G2 Scope, not improvised at the gate.
Crane failure near nuclear systems
Tip-over or boom collapse near a reactor building, fuel bay, or safety system is a worst-case event. Capacity utilization documented per pick ; the contingency matrix maps every safety-related system in the lift radius as keep-clear.
Six lift archetypes. Inside the station.
Nuclear lifts cluster into recurring engineering patterns — refurbishment, outage, and fuel-handling work, much of it inside controlled areas. Each archetype has its own load-case profile, dose constraint, and security regime. The methodology adapts ; the rigor doesn't.
Steam-generator replacement
The signature nuclear mega-lift — old steam generators removed and replacements installed through the reactor building. Multi-day, dose-managed, geometry-critical. CRANEbee 3D mandatory ; multiple peer reviews.
Reactor-component + refurbishment lifts
CANDU refurbishment component handling — calandria-adjacent work, feeder + end-fitting equipment, reactor-face tooling. Inside the highest-dose, tightest-geometry environment on site. Staged for minimum time-in-field.
Turbine + generator + condenser lifts
Turbine rotors, generator stators, condenser components, moisture-separator-reheaters in the turbine hall — conventional side, high-value, precision-set. Tandem-crane for the heaviest rotors.
Dry-storage cask + fuel-handling equipment
Spent-fuel dry-storage container handling, fuel-handling-system equipment, transfer-flask components. Among the most security- + dose-controlled lifts on site. Engineered to the licensee's fuel-handling procedures.
Heat-exchanger, pump + BOP lifts
Heat exchangers, primary + secondary pumps, valves, and balance-of-plant equipment during outage. Confined-building access, sequenced into the outage so the path is clear when the component moves.
Multi-pick outage campaigns
A nuclear outage is a tightly-sequenced campaign of lifts on the critical path. We plan the campaign — pick order, crane positioning, dose-managed sequencing, shared rigging — so the lifts flow without re-mobilizing mid-outage.
Nuclear in the field
From sector context to the lifts we engineer — a look at where this work happens.
The standards we work to.
The lift is our scope, so the standards we cite are crane + rigging standards — executed inside the licensee's nuclear quality + security management system. The reactor physics and the safety case belong to the licensee, not to us.
Mobile and locomotive cranes
The mobile crane safety standard — load charts, capacity, setup, operation. Cited on every nuclear lift plan as the methodology baseline.
Mobile crane safety + Quebec lift-plan code
The Canadian mobile crane standard ; in Quebec, Norme Z150 is the provincial lift-plan code. Cited on every engagement in its jurisdiction.
Management-system requirements for nuclear facilities
The Canadian standard for nuclear-facility management systems. Our lift deliverables are produced to integrate with the licensee's N286 management system — traceable, controlled, auditable.
Nuclear quality assurance
The nuclear QA program standard. Where the work falls under the licensee's NQA-1 program, our deliverables + rigging documentation align to the applicable quality requirements.
Slings + rigging hardware
Governs slings, shackles, links, and connecting hardware. Cited on the rigging spec of every lift — each component rated to the load, inspected to the nuclear program.
Regulator + dose-optimization
The Canadian Nuclear Safety Commission regulates the work ; ALARA governs dose. We document the lift's access posture + time-in-field optimization — we don't author the radiation-protection program, we plan the lift to respect it.
Four capability lines. One nuclear engagement.
Maxor's four service pillars all show up on a nuclear outage or refurbishment lift. Here's how each one earns its place — inside the station.
Sealed plans + emergency response
Outage- + refurbishment-sequenced lifts, single-crane to multi-crane tandem, dose-managed and planned as a campaign. Same-day emergency tier when a component failure threatens return-to-service. Capacity utilization per pick ; Z150 / B30.5 cited inline, produced to the licensee's N286 system.
Distribution + training + implementation
Steam-generator replacement, reactor-face work, and turbine-hall lifts modeled in CRANEbee before the crane sets up. Swing arc + safety-system keep-clear drawn against actual station geometry — and rehearsed to minimize time-in-field. We distribute, train, and implement the platform on Canadian nuclear projects.
Distribution + advisory + training
Dyneema® synthetic chains for confined, dose-managed lifts where lighter rigging cuts time-in-field, near energized + safety-related systems where steel conductivity is a hazard, and on finished surfaces where marking is unacceptable. Authorized Quebec distribution.
Deterministic engineering platform
The Maxor software line (Heisen, Maxor Audit, Maxor Ground) provides the audit-grade evidence substrate behind the sealed lift plans — recallable lift records, outage-campaign provenance, N286-traceable, sovereign deployment.
Beyond the four pillars — software built for your operation.
The four service pillars cover the lift. But most nuclear operators carry a software gap the off-the-shelf vendors never close. We build it — custom applications, integrations, and managed services, same engineering posture, same team from kickoff to go-live, sovereign by default, N286-aware. Engineered in Canada, owned by you.
Heisen — our deterministic intelligence layer — is optional on any build: embed it or not, your call. Either way it plugs into a fresh custom app or your existing third-party software via API.
Outage-campaign planning + dose tracking
Sequences outage lifts against the critical path, crane availability, and dose budget — so the station returns to service on the planned hour with the crew's exposure engineered down.
Lift records + N286 evidence registry
A registry of every sealed lift tied to the component + the N286 management system — traceable, controlled, recallable for the next outage or CNSC review instead of re-assembled.
Deterministic engineering compute (Heisen)
Heisen deterministic compute for the engineering analysis behind a high-consequence lift — reproducible, audit-trailed, explainable. The analysis re-runs to the same answer under regulatory review.
