II. Discussion 

The NRC Office of Nuclear Regulatory 

Research (RES) is advancing the 

understanding and state-of-practice for 

modeling High Energy Arcing Faults 

(HEAF) in fire Probabilistic Risk 

Assessment (PRA). One important 

aspect of this research is the ability to 

reliably predict the HEAF hazard for 

various scenarios important for nuclear 

safety. The high intensity and short 

duration of a HEAF has not been 

explicitly modeled in past fire PRA 

methodologies. As such, there was a 

need to advance HEAF modeling 

capabilities to reliably predict the 

scenario specific HEAF hazards to 

support refinements to the zones of 

influence (ZOI) used in fire PRA. The 

NRC worked with its collaborative 

research partners to develop two models 

to predict the HEAF hazard. 

In the report titled, ‘‘Predicting High 

Energy Arcing Fault Zones of Influence 

for Aluminum Using a Modified Arc 

Flash Model, Evaluation of a modified 

model bias, uncertainty, parameter 

sensitivity and zone of influence 

estimation, Draft for public comment,’’ 

the NRC worked with Sandia National 

Laboratories to evaluate an existing base 

model. Differences between the base 

model and nuclear power plant fire PRA 

scenarios were identified. Modification 

of the base model established from 

existing literature and test data was 

used to minimize these differences. The 

modified model was evaluated against 

NRC datasets to understand the model 

prediction and relative uncertainties. 

Finally, a range of fire PRA ZOIs were 

developed based on the modified model 

and draft update HEAF PRA 

methodology. The results are expected 

to be used to inform an update to ZOIs 

used in fire PRA. 

In the report titled, ‘‘Determining the 

Zone of Influence for High Energy 

Arcing Faults using Fire Dynamics 

Simulator, Draft for public comment,’’ 

the NRC worked with the Electric Power 

Research Institute and the National 

Institute of Standards and Technology 

to adapt a computational fluid dynamic 

code known as the Fire Dynamics 

Simulator (FDS) to predict the HEAF 

hazard. This report documents (1) the 

development of the approach to use FDS 

to predict thermal exposures to targets 

from a HEAF, (2) validation of the 

model and (3) application of the model 

to estimate HEAF ZOI for a broad range 

of fire PRA HEAF scenarios. 

The draft research information letter 

reports present the NRC–RES/Sandia 

National Laboratories (SNL) and NRC– 

RES/Electric Research Power Institute 

(EPRI) working groups efforts to predict 

realistic HEAF hazards. The two 

approaches to model HEAF hazards 

present complementary but diverse 

methods to estimating the hazard ZOI. 

For most scenarios the two approaches 

provide results that are consistent with 

each other. The NRC–SNL report can be 

viewed as a first order approximation 

providing a single value scenario 

specific ZOI estimate, while the NRC– 

RES/EPRI report provides additional 

geometric detail to the ZOI estimate.
