Question 1

A nuclear power plant has experienced an event involving a major failure of plant functions needed for public protection, with the potential for significant, uncontrolled radioactive releases. Sirens in the 10-mile Emergency Planning Zone (EPZ) have been activated. Which NRC emergency classification level does this scenario describe?

Accepted Answer

Site Area Emergency

Answer

A Site Area Emergency involves a major failure of plant functions with the potential for significant radioactive releases. Key indicators include the activation of sirens to alert the public within the EPZ to tune to emergency broadcast stations. While serious, it has not yet progressed to an actual or imminent loss of core integrity, which would be a General Emergency.

Question 2

During a declared emergency, who holds the primary responsibility for making decisions on Protective Action Recommendations (PARs), such as evacuation or sheltering-in-place, for the general public?

Accepted Answer

State and local government officials

Answer

While the nuclear plant licensee provides Protective Action Recommendations (PARs) based on plant conditions and dose projections, the final decision-making authority for implementing protective actions for the public rests with state and local government officials.

Question 3

What is the primary purpose of an Emergency Action Level (EAL) in a nuclear power plant's emergency plan?

Accepted Answer

To provide pre-determined, observable triggers for classifying an emergency.

Answer

Emergency Action Levels (EALs) are specific, pre-determined, and observable criteria used to classify operational events into one of the four emergency classifications (Unusual Event, Alert, Site Area Emergency, General Emergency). They are designed to ensure timely and consistent emergency classification and response.

Question 4

A fire breaks out in a non-safety-related support building at a nuclear power plant. The fire is extinguished within 10 minutes, there is no damage to plant safety systems, and no radioactive release has occurred. What is the most likely emergency classification for this event?

Accepted Answer

Unusual Event

Answer

An Unusual Event is the lowest of the four emergency classifications. It involves a situation where there is a potential degradation in the level of plant safety, but no significant threat to public health and safety. A minor, quickly extinguished fire in a non-critical area fits this description.

Question 5

Which of the following best describes the role of the Emergency Response Organization (ERO) at a nuclear facility?

Accepted Answer

A dedicated team of trained plant personnel who staff designated response facilities to mitigate an emergency.

Answer

The Emergency Response Organization (ERO) is composed of trained and qualified licensee personnel who are assigned specific responsibilities to respond to an emergency. They report to designated emergency response facilities (like the Technical Support Center and Emergency Operations Facility) to manage and mitigate the event.
