When the body or any specific organ is exposed to radiation, the amount of
radiation received is called..?
Dose
Fission
The man-made process of splitting an atom
Radiation doses are measured in units called
REM or Millirem
Contamination
Occurs when a tiny particle of radioactive material gets outside the place it is intended
to be.
140 mrem
Radiation worker occupational dose
General public radiation dose
100mrem per year
Chain reaction
Neutrons released from split atoms cause other atoms to split
The average dose for station workers from both background and occupational
sources of radiation is
760 mrem per year
Owner Controlled Area (OCA)
Is all the company property immediately surrounding the protected areas security fence.
Access is normally limited to people on official business
What is the first group you encounter when approaching the plant?
Security
Tailgating
Following a worker through a security door without using the card reader
Vital Area (VA)
Contains safety-related equipment inside the protected area. The Failure or damage of
safety-related equipment in this area could prevent safe shutdown of the reactor and
possibly endanger the public health and safety by exposure to radiation
Protected Area (PA)
Is inside the security fence. All of this area can be considered "the plant". You must
have a badge issued to you by security to go in.
Accompany the visitor to the Protected Area exit
When a visitor has completed their job, the escort should:
the exit portal contamination monitor
As you exit the Protected Area you will pass through
the exit portal contamination monitor
What device checks all employees for radioactive contamination
The three plant boundaries are:
Owner Controlled area, Protected Area, and Vital Area
, Security officers
Protects the plant and its workers, and guard against nuclear sabotage
Self-checking
A mental process that helps you prevent human errors.
STAR
What is the self-checking process?
S: STOP T: THINK A: ACT R: REVIEW
What does STAR represent?
Outages
A time when the station is shut down for refueling or maintenance
NRC Form 3
Is a notice to employees describing their rights and responsibilities at nuclear plants
Willful Misconduct
Any action by an employee or contractor to willfully violate NRC requirements or to
cause the company to be in violation of those requirements
The Operations department
Responsible for the "hands-on" control of the plant.
Maintenance Department
Keeps the plant equipment in good operating condition.
The Radiation Protection (RP) Department
Limits the radiological exposure of workers and prevent the accidental release of
radioactive material. (Also called Health Physics at some plants.)
The Electronic Alarming Dosimeter (EAD)
(Most commonly used) Shows your radiation dose on a digital display and provides and
audible alarm when it reaches a dose or dose rate limit.
The Training Organization
Helps train and qualify workers for their jobs and has three main functions
the Quality Program
Spot checks plant activities to ensure they follow procedures and meet certain
standards.
Quality Assurance
Provides confidence that equipment and structures will work properly in service. They
do not supervise work, they provide an independent check of completed work. They
conduct periodic audits and surveillance's
Surveillance
What is the act of observing activities and hardware, and/or reviewing document ion to
verify conformance with specified requirements and to evaluate their adequacy and
effectiveness
Quality Control
The personnel that conduct inspections and test to verify that certain characteristics
have been met. They also check compliance with documented instructions, procedures,
and drawings.
The Safety Department
Provides oversight of the industrial safety program.
Emergency Planning
Provides guidance on what to do in case of emergency
