REVIEW TEST • UNIT 3
Directions: Circle the letter of the answer that best completes the statement given.
- The site characterization studies at Yucca Mountain focused on:
- methods for transporting waste to Yucca Mountain
- methods for handling waste
- features and processes that are important to the repository’s safety
- public attitudes about the repository program
- The site characterization program involved all of the following studies, EXCEPT:
- evaluating technologies for reducing the amount of waste
- measuring how much water infiltrates the surface of Yucca Mountain
- determining the past climate conditions at Yucca Mountain
- testing the strength of the rock
- The Exploratory Studies Facility is a/an:
- building for storing samples of rock
- underground laboratory used for studying the rock at the repository level
- simulation of the repository environment
- facility for testing corrosion-resistant materials
- The environmental studies at Yucca Mountain evaluated the impacts of project activities on all of the following, EXCEPT:
- native plants
- Native American cultural resources
- native vertebrate species
- native uranium
- An analogue is a/an:
- computer model of how water moves through rock
- study of how a repository could affect animals in the area
- process found in nature that is similar to one that could occur in a repository
- experiment to test the durability of the waste packages
- The “Total System Performance Assessment” is a/an:
- computer simulation that shows how all the repository’s parts will work together for tens of thousands of years
- method for testing corrosion-resistant materials
- experiment that shows how heat would affect the repository environment
- study of a uranium deposit in Mexico
- The “Basin and Range” is characterized by its:
- close proximity to the ocean
- mountain ranges separated by basins
- dry climate
- large lakes
- Yucca Mountain was formed by:
- tectonic plates moving over one another
- erosion of the land around the mountain
- deposits of ash from nearby volcanoes
- a tunnel boring machine
- Yucca Mountain is made of layers of:
- granite
- basalt
- sand and gravel
- tuff
- It is less likely that earthquake shaking would affect the waste in a deep underground repository because::
- an earthquake will never happen at Yucca Mountain.
- earthquake shaking decreases with the depth underground
- the waste packages are built to withstand earthquakes
- zeolites in the rock will absorb the movement
- Very little rainfall moves into the rock of Yucca Mountain due to all of the following reasons, EXCEPT
- water evaporates from the surface
- the soils and terrain cause water to run off the surface
- the roots of plants take up the water
- it never rains in southwestern Nevada
- The unsaturated zone under Yucca Mountain is an area where:
- the rock has no fractures
- the rock’s fractures are filled with water
- the pores in the rock are filled with water
- the pores in the rock are not filled with water
- The groundwater under Yucca Mountain:
- is isolated within a closed basin
- seeps into an aquifer that supplies water to Las Vegas
- eventually flows into the Pacific Ocean
- eventually flows into the Colorado River
- The emplacement tunnels for storing the waste will be excavated in solid rock about ___ meters below the surface of Yucca Mountain.
- 30
- 50
- 300
- 3500
- The underground location of the emplacement tunnels is based on all of the following factors, EXCEPT:
- the thickness of the overlying rock and soil
- the distance from the nearest town
- the location of the fractures in the rock
- the depth to the water table
- The repository’s engineered features include all of the following, EXCEPT:
- waste packages
- drip shields
- tunnel boring machines
- tunnel inverts
- The purpose of the repository’s surface facilities is to:
- isolate nuclear waste for thousands of years
- manufacture waste packages
- prepare nuclear waste for underground disposal
- generate nuclear power
- The primary reason for using robotic equipment during repository operations is to:
- reduce costs
- protect workers
- improve productivity
- increase efficiency
- The repository will not be closed and sealed off until:
- the emplacement tunnels are full of nuclear waste
- future generations decide to do so
- the next ice age
- another repository is built
- An example of a “passive institutional control” is a/an:
- aboveground storage structure for nuclear waste
- law that prohibits people from entering the repository
- security gate that keeps people out of the repository area
- marker for warning future generations of the radioactive material located underground
