Survey Key Items
• STD 1020
• Developing probabilistic hazard assessments for wind,
precipitation, flood and volcanoes will require time and effort.
• New NPH for Volcanic.
• Shifting of PC to SDC/Limit States – not a clean crosswalk.
• Requirement of deformation limits for Criticality Safety.
• STD 1066
• DOE STD 1066 invokes the American Glovebox Standard (AGS)
that is very onerous relative to FHA/FSA for gloveboxes.
• Implementation of STD 1066 is considered the most difficult given
the confusion on applicability to existing facilities … we will have a
revised contract appendix defining our fire protection requirements.
• Design
• For design, most issues relate to the implementation of the national
standards added to the order.
Alternative Approaches
• Quantitative analysis is only being applied to new facilities
and major modifications. Otherwise, the qualitative
analysis required in 420.1B is being grandfathered.
• … a requirements analysis and documented the
alternative approaches … whereas following a
“requirement” (e.g., shall statement) in 1066 would not be
realistic and/or very costly without any fire safety benefit.
For example, using the current versions of all codes and
standards which is a departure of how the building code
(IBC) is supposed to be administered.
