Moving Towards more Realistic Cabinet Damage Rob Cavedo
Potential Realism Improvement All trains and functions that can be affected by a fire are assumed to occur at the cabinet ignition frequency.
For most cabinets, this is a mildly conservative assumption (e.g. breaker goes open/breaker goes closed).
For cabinets that control multiple trains from different power supplies, this can be overly conservative.
Industry events of cabinets with multiple trains do not show the loss of all trains (e.g. single alarm card damaged others functional, single HS malfunction, etc.).
1 Moving towards more Realistic Cabinet Damage
Identification of Relevant Guidance NUREG/CR-6850 Section 8.5.1.2 (pg. 8-10) 2 Moving towards more Realistic Cabinet Damage
Proposed Approach to Enhance Realism Use a 25% chance all functions in a cabinet are lost and a 75% chance a single function is lost. This is based on a review of the sixteen control cabinet scenarios in the Fire Events Database (FEDB) only three are considered to represent broad damage to the cabinet.
A train is defined as any equipment in the cabinet powered from the same ultimate external power supply to the cabinet.
If all equipment in the cabinet is powered from the same external source, then this method cannot be applied.
This would only apply to scenarios with NO EXTERNAL damage. If the fire is large enough to damage external equipment, then larger internal losses are expected.

The insulation breakdown was located where the insulation came in contact with a protruding tap of a wire wound power resistor.
Insulation breakdown due to aging (25 years) and water intrusion.
