NNTF Recommendations PrioritizationTier 1 To be implemented without unnecessary delay, required skills and

resources are available:Seismic and flooding hazard re evaluation• Seismic and flooding hazard re-evaluation

• Seismic and flooding walk-downs• Hardened vents for MARK 1 & 2• SFP Instrumentation

Tier 2 To be implemented once further technical assessments have been performed and critical skills and resources have been ensured availablep

Tier 3 • Implementation highly dependent on results of tier 1 and 2 implementation

• Coherent integration of EOP SAMG EDMGCoherent integration of EOP, SAMG, EDMG

Rule- making for Tier 1 implementation underway (today 3 recommendations to be i l t d b f 2017)implemented before 2017)
