Appendix C

technical safety

Those requirements that define the conditions, safe boundaries,

requirements (TSR)

and the management or administrative controls necessary to

ensure the safe operation of a nuclear facility and to reduce the

potential risk to the public and facility workers from uncontrolled

releases of radioactive materials or from radiation exposures due

to inadvertent criticality. Technical Safety Requirements consist

of safety limits, operating limits, surveillance requirements,

administrative controls, use and application instructions, and the

basis thereof.

time-dependent action steps

Action steps that impose time requirements on the user by

specifying the duration of an action or actions that must be

completed within a specific period of time.

user

The person(s) actually performing the procedure.

verb

The part of speech used to indicate an action or state of being.

verification

Verification involves action steps that direct users to see if a

parameter has assumed a specified value or to see if a specific

action has been carried out, and, if it has not, to take actions to

make it so.

walkdown

A walkdown is that segment of a walkthrough which consists of

physically visiting and observing the location in which the

activities are to be performed and the equipment that will be used.

A walkdown is performed to ensure that the equipment and

environment are actually as envisioned and the people involved

can perform the required tasks.

walkthrough

The walkthrough is the cumulative, detailed check of the process

and facility. Activities that may be used to complete walkthroughs

include walkdowns, simulations or modeling.

warning

Warnings alert users to conditions, practices, or procedures that

must be observed to avoid loss of life or severe injury. Warnings

alert users to potential hazards to personnel.
