Bess Fire Containment Ventilation Feeder Package

Calculates source-bound BESS fire and feeder metrics from deterministic SSC-17 and SSC-19 task-owned source packs. The template combines usable storage energy, ventilation airflow, HRR containment, safety energy load, feeder voltage drop, and an overall synthetic pass score.

with-tool: The model is given an executable Python calculator script.

Difficulty

Each template is sampled at three tiers. Harder tiers may hide inputs, forcing the model to infer them from the scenario description.

All inputs remain visible at every tier

For this template, difficulty scales through parameter and scenario ranges rather than hidden information.

easy:
All source-pack values given for the SSC-17 BESS safety and feeder package
medium:
All source-pack values given for the SSC-17 BESS safety and feeder package
hard:
All source-pack values given for the SSC-17 BESS safety and feeder package
