Commissioning software for nuclear balance-of-plant where the turbine island and its support systems still need the same rigour as safety-classified systems, just against a different QA level.

The turbine island, feedwater trains, condensate polishing, circulating water and cooling towers represent a large share of total plant commissioning scope, executed by conventional power plant contractors who may be less familiar with nuclear interface control requirements than the nuclear island team.

When balance-of-plant test records live entirely separately from the nuclear island's register, an interface point — a feedwater isolation valve, a turbine trip signal into the reactor protection system — can be commissioned as if it were a standard fossil-plant component, missing the interface verification the nuclear licensing basis actually requires.

Deskely tags balance-of-plant systems in the same register as the nuclear island, flagging interface points to safety-classified systems explicitly, so those specific tests get nuclear-appropriate rigour without imposing SC1-level QA on the entire turbine island unnecessarily.

Turbine generator commissioning proceeds through OEM start-up sequences, overspeed trip testing and electrical protection testing, captured with standard commercial-grade rigour except where the system interfaces with the reactor protection or engineered safety features actuation system.

Feedwater and condensate systems are functionally tested for flow, pressure and level control, with any signal or valve identified as a nuclear interface point subject to an additional verification test proving the interface behaves correctly under both normal and upset conditions.

Punch items are categorised by whether they touch a flagged interface point, so a routine turbine island punch item does not receive the same escalation as a discrepancy on a feedwater isolation signal feeding the reactor protection system.

A turbine generator OEM or a conventional civil contractor may never have worked to ISO 19443 or an equivalent nuclear supply chain QA standard before, and the gap between their normal commercial-grade documentation habits and what a nuclear interface test record actually requires is where nuclear projects lose the most time reworking paperwork rather than reworking hardware.

Independent nuclear assurance reviewing balance-of-plant scope focuses almost entirely on the flagged interface points rather than the turbine island as a whole, because that is where a QA shortfall actually threatens the licensing basis; a review that instead tries to impose full nuclear QA rigour across the entire non-safety scope wastes the assurance function's time and slows a contractor who was never going to touch a safety-classified system anyway.

Deskely gives the balance-of-plant contractor a normal commercial-grade workflow for the bulk of their scope, while automatically routing any component flagged as a nuclear interface point into a record format independent nuclear assurance can review without a special request, so the QA culture gap is managed at the interface rather than argued about for the whole contract.
