Which component is used to deliver borated water to the core during accidents?

• A. HPSI pumps deliver borated water to the core
• B. Accumulators deliver borated water to the core
• C. Injection lines deliver borated water to the core
• D. Control rods deliver borated water to the core

Answer: (C)

During an accident, borated water is used to cool the core and absorb neutrons to slow the reaction. The part that actually brings that borated water to the core is the injection lines—the piping that conveys water from the emergency sources into the reactor coolant system and into the core. Pumps like the high-pressure safety injection pumps provide the pressure to push water through these lines, and accumulators supply borated water that can be released along the same injection paths. Control rods, by contrast, are neutron absorbers inserted into the core and are not responsible for delivering borated water.
