A question has recently been identified regarding whether fire-induced flooding had been analyzed for scenarios involving high density polyethylene (HOPE) piping.
Please provide a description of how potential flooding has been addressed in the analysis. The description should describe how safe shutdown is assured through either demonstrating that the HOPE installations are bounded by existing analysis, or by performing a risk-informed, performance-based evaluation that considers the possibility of flooding. All areas containing HOPE piping should be included in the response.
