[10 CFR 820.2]

PRESTART FINDING. A finding that must be corrected before an activity can be started.

PRE-TRANSFER REVIEW. Serves to provide the safety basis and physical and

administrative characteristics of the facility subsequent to the cessation of operations, and prior

to transferring the facility for the disposition phase. The objective of the review is to identify and

evaluate, using a graded approach, the explicit boundaries of the facility(ies) being transferred;

their physical condition; extent, nature and level of contamination (as appropriate on a case-by-

case basis); inventories/estimates of types and quantities of special nuclear, fissionable, and

toxic, hazardous, and radioactive materials; summary and evaluation of the safety basis and

surveillance and maintenance requirements; and other elements to ensure that sufficient

information is provided to facilitate an understanding of the facility and its surveillance and

maintenance requirements. Documentation is generally expected to be provided from the

analysis of available information, without extensive, new, characterization work. [DOE G

433.1-1]

476.

PREVENTIVE MAINTENANCE. All those systematically planned and scheduled actions

performed for the purpose of preventing equipment, system, or facility failure. [EH62dd1]

477.

PRIMARY ENVIRONMENTAL MONITORS. Monitoring equipment legally required to

monitor ongoing discharges. In general, this term applies to monitors closest to the point of

discharge which are used to determine if discharges are within specified limits. It also includes

any equipment which actuates automatically in response to set level signals from such a monitor.

It does not include equipment in general area, remediation, or compliance monitoring programs.

(See Continuous Air Monitoring, Monitoring, Performance Monitoring, Personal Monitoring,

Personnel Monitoring, Post-Accident Monitoring Equipment, Safety Class Monitoring

Equipment, and Secondary Environmental Monitors) [DOE O 5000.3B] [EH62dd1]

478.

PROBABILISTIC METHOD. A technique which uses distributions of parameters (including

uncertainty and randomness) to perform an analysis. Results are expressed in terms of

probabilistic distributions, which quantify uncertainty. [DOE O 5480.28] [EH62dd1] [DOE G

420.1-2]

479.

PROCEDURE. A document that prescribes a process (a sequence of actions) to be

performed to achieve a desired outcome. [EH62dd1] [DOE G 450.4-1B]

480.

PROCESS. A series of actions that achieves an end or result. [10 CFR 830.3]
