would be corrective maintenance, but scheduled repacking prior to leakage would be

planned maintenance. [DOE G 433.1-1]

457.

PLANNED SHUTDOWN. A facility shutdown required to perform scheduled activities

(such as programmatic or equipment adjustments, reactor refueling, maintenance,

surveillance, tests, inspections, and/or safety upgrades) or for programmatic reasons

unrelated to the facility's ability to operate, such as a funding shortfall, is a planned

shutdown.

PLUTONIUM PROCESSING AND HANDLING FACILITY. Any facility constructed

primarily to process plutonium (Pu) (including Pu 238) and that handles substantial

quantities of in-process Pu where there is a possibility of a release of Pu to the environs

under normal operations or design basis accident conditions in excess of limits set forth

in the directive on Radiation Protection of the Public and the Environment in the DOE

5400 Order series. [DOE O 6430.1A]

459.

PLUTONIUM STORAGE FACILITY (PSF). Any facility constructed to store strategic

(category I) quantities of plutonium. [DOE O 6430.1A]

POLICY STATEMENTS. A policy statement is a top level DOE directive which is the

Department's statement of nuclear safety philosophy and values. All other requirements

and guidance flow from and must be consistent with the policy. It applies equally to the

work of DOE Elements and the work of contractors and subcontractors conducting

activities in DOE Nuclear Facilities. The DOE nuclear safety policy, currently stated in

SEN-35-91, will be incorporated into the DOE directives system. The directive on

nuclear safety policy will include a set of supporting topical policy statements which,

when implemented, will support the nuclear safety policy. The directive on nuclear

safety policy will necessarily be general and will be implemented through more specific

basic nuclear, safety requirements established in DOE Regulations and Orders. [DOE N

1321-138] [EH62dd1]

461.

POLLUTION PREVENTION. A source reduction as defined in the Pollution Prevention

Act, and other practices that reduce or eliminate the creation of pollutants through 1)

increased efficiency in the use of raw materials, energy, water, or other natural resources;

or 2) protection of natural resources by conservation. The DOE has expanded this

definition to include recycling. [DOE G 450.1-1]

462.

POST-ACCIDENT MONITORING (PAM) EQUIPMENT. Equipment and

instrumentation necessary to monitor the parameters necessary to assess facility and

environs conditions both on-site and off-site, during and following an accident. PAM

equipment and instrumentation must have an extended operating range or measuring
