CESSWI PART 1 EXAM SCRIPT 2026 TESTED
QUESTIONS WITH COMPLETE ANSWERS
GRADED A+
⩥ Civil Design. Answer: ALL buildings must be designed for dead load,
live load, and wind load
⩥ Nuclear SSC's that are important to safety must be designed to w/
stand effects of?. Answer: ADDITIONAL natural phenomena
(earthquakes, floods, hurricanes, tornadoes) à must keep their safety-
related functions
⩥ Soil-Structure Interaction. Answer: Dynamic response of a structure
coupled to its supporting medium
⩥ Soil-Structure Interaction. Answer: Response depends on: earthquake
ground motion, surrounding soil profile, and the structure itself
⩥ Strong Soil-Structure Interaction. Answer: - Motion at base is NOT
the same as ground motion (recorded at a distance away)
⩥ Little or No Soil-Structure Interaction. Answer: Motion at base is
basically the same as ground motion (recorded at a distance away from
structure
,⩥ Little or No Soil-Structure Interaction. Answer: -Low levels of S-S
interaction are allowed for: light, surface founded structure or founded
on rock/ stiff
soil
- Ex: 1 story house/ building
⩥ Strong Soil-Structure Interaction. Answer: - Strong soil-structure
characteristics: massive structure, partially embedded in ground, soft soil
deposit
- Ex: Nuclear containment
⩥ Compaction. Answer: = measure of density of soil in field at specified
moisture content
⩥ Soil Stability. Answer: The plant must be placed on engineered
backfill/ bedrock and CE's must determine backfill material and
compaction needed
⩥ If soil Does not meet requirements, buildings/ eqpt would be unable to
w/stand effects of an earthquakes?. Answer: True
⩥ Soil-Structure Analysis should account for?. Answer: Variation of soil
properties with depth
, ⩥ Soil-Structure Analysis should account for?. Answer: Uncertainties in
the measured/determined soil properties
⩥ Soil-Structure Analysis should account for?. Answer: Material
nonlinear behavior of the soil
⩥ Soil-Structure Analysis should account for?. Answer: Possible
interaction with neighboring structures
⩥ Soil-Structure Analysis results are used for?. Answer: basis of design
of major structures & input on which equip. systems & components are
qualified @ nuclear power plant.
⩥ Can a single analysis account for all soil effects?. Answer: No, various
approaches are used
⩥ Soil-Structure Considerations: Weight could exert force on adjacent
buildings below ground level walls and change?. Answer: structural
loading
⩥ Soil-Structure Considerations: Why do footings need to be placed?.
Answer: prevent sliding into adjacent buildings
