My external validation/reference source permits linear interpolation of this capacity relationship between the entered points for the applicable reactor/model, target/reference dose, UVT basis, lamp/configuration basis, and operating envelope.

Leave this off for exact entered reference points. When on, document the source above and confirm it covers this reactor/model, target/reference dose, UVT basis, lamp/configuration, and operating envelope. ATLAS does not independently verify the source or interpolation rule.

Entered reactor performance/reference data

Enter two or more unique UVT points for one reactor at the entered reference dose. Rows can be entered in any order.

UVT (%)	Entered reference flow capacity (m3/h/reactor)	Remove
Reference point 1 UVT (%)	Reference point 1 flow capacity in cubic metres per hour per reactor
Reference point 2 UVT (%)	Reference point 2 flow capacity in cubic metres per hour per reactor

Use UVT values at the same wavelength and optical path length as the entered external reference data; EPA UVDGM commonly uses 254 nm and 1 cm. No absorbance or path-length conversion is applied. Each UVT must be greater than 0% and no more than 100%. Each entered reference flow capacity must be positive. Duplicate UVT values are rejected.

Méthodologie

Dimensionne les réacteurs en service et de secours à partir de points externes UVT/capacité saisis, avec un point exact par défaut. L’interpolation n’est possible que si la source externe documentée l’autorise pour le réacteur et l’enveloppe d’exploitation concernés; aucune extrapolation ni dose réglementaire automatique.

At an exact design UVT match, capacity is taken from that exact entered reactor performance/reference point.

For an intermediate UVT, bounded linear interpolation is available only when the user confirms that the external validation/reference source permits this capacity relationship for the applicable reactor/model, target/reference dose, UVT basis, lamp/configuration basis, and operating envelope, and documents that source. This interpolation is user-authorized from entered external reference data; ATLAS does not independently validate it. No extrapolation is used.

EPA UV reactor validation is based on reactor-specific validated operating conditions. Dose/RED relationships with flow, UVT, lamp status/intensity, and other operating parameters depend on the reactor and validation method. ATLAS does not derive a generic UV dose-monitoring equation. Boundedness alone does not establish that linear interpolation is valid.

UVT values must use the same wavelength and optical path length as the entered external reference data; no absorbance or path-length conversion is applied.

Duty reactor count = ceiling(plant design flow / capacity per reactor from entered external reference data). Installed count = duty reactors + entered standby reactors.

Operating duty power = duty reactors x entered per-reactor electrical power. Standby reactors are not assumed energized.

The user-selected target dose must match the user-entered reference-dose value; neither dose value is calculated by this tool.

Périmètre / Limites

Un point de référence saisi exactement est utilisé par défaut. L’interpolation linéaire bornée n’est possible que si l’utilisateur documente son autorisation par une source externe. L’outil n’extrapole pas et n’établit pas de crédit de dose UV validé.
This is a screening calculation over user-entered reactor performance/reference data. The tool does not verify the external source or the entered data and does not establish regulatory UV dose credit.
Lamp power, flow, and UVT alone are not used to derive UV dose. The tool does not model reactor physics or CFD.
No theoretical fluence, RED, Validation Factor, pathogen dose requirement, organism-specific log inactivation, dose-monitoring equation, lamp/intensity physics, organism credit, manufacturer selection, or regulatory compliance logic is calculated.
Use the UVT wavelength and path length specified by the external source (EPA UVDGM examples commonly use 254 nm and 1 cm).
