Radiolytic Gas Generation

Calculate gas generation from absorbed radiation energy and species-specific G-values. Radiolysis is independent of chemical stoichiometry — each species is computed from its own G-value.

EXAMPLE MODEL — NOT A CERTIFIED PACKAGE OR SAFETY BASIS
G-values are material- and radiation-dependent parameters. Do NOT use invented regulatory values. All fields are user-supplied and provenance-aware. H₂ generation ≠ 2 × O₂ generation unless explicitly specified.
Engineering estimates only — not safety certification or code compliance. Results must be independently validated by a qualified engineer.

Radiation Components

If absorbed power is provided directly, it is used. Otherwise: absorbed = emitted × fraction.

Radiolytic Yields (G-values)

Each species is computed independently. No electrolysis stoichiometry is enforced.

Canonical Containment Scenario

Canonical Engine
Uses the canonical containment engine: radiolytic generation → gas inventory → pressure (ideal gas, sealed volume) → filter sink. Initial headspace is explicit (vacuum, air, or inert). Absolute pressure and pressure increase are reported separately.

Resolved initial condition: Air-filled · 101325 Pa

* Free volume ≠ internal volume. User-supplied value takes priority over package defaults.

Reference Scenario: Radiolytic H₂ Accumulation

REFERENCE ENGINEERING EXAMPLE — NOT PACKAGE CERTIFICATION. Use of an authoritative package geometry does not imply that the modeled contents, conditions, or results constitute an authorized shipment, package certification, or safety-basis determination.

* Free volume ≠ internal volume. Must be user-supplied — the package profile does not define it.
