DEFINITION
That portion of the BUILDING991 COMPLEX in which the
credited safety hction provided by a single system, subsystem,
train, component or device is compromised by an
OUT-OF-TOLERANCE or other CONDITION for which
REQulRED ACTIONS are specified.
Summary statement(s) of the rationale for the LCOs and
associated SRs and ACs. The BASES explain how the numeric
value, the specified function, or the surveillance fulfills the
credited safety function assumed in the FSAR Safety Analysis.
The set of facilities supporting the mission of Building 991 to
store transuranic (TRU) waste containers and to stage Special
Nuclear Material (SNM) in preparation for off-site shipment. Ths
includes Building 991, Building 996, Building 997, Building 998,
Building 999, Building 984, Building 985, Building 989, and
Building 992.
The amount of time allowed to complete a REQUIRED ACTION.
The COMPLETION TIME starts whenever a situation (e.g., not
OPERABLE equipment or variable not within limits) is
DISCOVERED that requires entering the REQUIRED ACTION
for a given CONDITION. REQUIRED ACTIONS shall be
performed before the specified COMPLETION TIME expires,
except as specified under SU*END OPERATIONS.
Configuration and status of the facility related to compliance with
the TSRs for which REQUIRED ACTIONS are performed withm
specified COMPLETION TIMES, including;
1. Discrete degradations of LCO-related SAFETY SSCs; and
2. Noncompliance with ACs.
A functional (performance language) statement depicting
analytical assumptions embodied in safety analysis specific to a
given program. These functional statements relate to assumptions
that determine the progression of accident scenarios.
Engineered features and/or administrative programs or program
elements which are not used in analysis to reduce frequency or
consequences but add additional levels of safe operations. Margin
of safety is established by the bounds of the analysis and is not
impacted by the loss of, or deficiencies in, DEFEYSE-IN-DEPTI-I
items.
