General Plant Access Flashcards
What is the difference between Boiler Water Reactor and a Pressurized Water Reactor?
Pressurized water reactors have a steam generator- and condensing water separate
Nuclear fission
Nuclear fission is the splitting of the nucleus of uranium which releases energy,as in a nuclear
Radioactive material
Anything that contains decaying atom and is releasing radiation is called radioactive material
Radiation
The energy that’s released when an atom splits or decays
Contamination
Occurs when a tiny particle of radioactive material gets outside the place it is intended to be when this happens ,the radiation it releases is no longer controlled
Dose
When the body or any specific organ is exposed to radiation,the amount of of radiation that it receives is called dose this is measured in units called rem or millirem (1/1000rem)
Back ground
Is radiation is radiation everyone receives from natural and man made sources. National sources such as the sun and some types of rock,and man made sources such as medical treatment and Xrays ,contrive much more dose than occupational dose.
Occupational dose
This dose , on average will be less than what you receive from background
Contract the average amount of radiation received by radiation workers and members of the general public
The average occupational dose received by a radiation worker at a nuclear power plant is the us is 140 mrem ( less than one fourth the amount of dose received from background
Station worker exposure versus regular person
Stationworker - Both background and occupational source of radiation is 760 mrem per year
Regular person - 300mrem
Purpose and the function of the security department is
Protect the plant and its workers,and protect against nuclear sabotage
. Control protection and vital area access
. Issue access badges
. Control security doors within the plant
.protect against the theft of special material
Written and verbal security guidance
Everyone shall follow
S T A R
Stop plan and prepare
Think think about you are supposed to do and what results you expect
Act perform the action
Review verify that you got the correct response
Protected equipment outages
Extra barriers are put in place around equipment needed to cool the reactor core these areas are identified as protected equipment.
There are two common legal records of your dose used in the nuclear industry
. Thermoluminescent dosimeter
. Optically stimulates dosimeter
