ShelterFactor Radiological Resilience

ShelterFactor knowledge base

Request an Assessment

A ShelterFactor assessment starts with the existing dwelling and identifies proportionate improvements.

Proposed assessment scope

  • Building layout and candidate protected rooms
  • Envelope and ventilation characteristics
  • Airborne-contamination protection opportunities
  • External-radiation shielding opportunities
  • Critical electrical loads and backup-power architecture
  • Remote activation, local controls and communications resilience
  • Water, sanitation and longer-duration habitability
  • Monitoring, alarms and operational procedures

Resilience is part of the design basis

An engineered shelter should be assessed under degraded conditions as well as normal operation. This includes grid failure, loss of internet connectivity and failure of remote automation. Where remote activation is required, the assessment should define secure remote control, local fallback, status confirmation and the behaviour of the system after communications or power loss.

For battery-backed systems, the assessment identifies the critical loads and calculates expected operating time rather than assuming that nominal battery capacity equals usable shelter autonomy.

From scan to engineering

The intended workflow is: initial scan โ†’ measured assessment โ†’ design basis โ†’ engineering specification โ†’ installation by competent partners โ†’ commissioning and validation.
