features and systems credited with prevention andor mitigation of accidents. This is
accomplished by ensuring the proper review, approval, and documentation of changes to safety
SSCs and non-safety SSCs that could impact safety SSCs. The program stipulates that
operation, maintenance, and modification of safety SSCs, and non-safety SSCs that could impact
safety SSCs, rely on the development and use of properly authorized work plans, procedures and
training. Further, the program ensures that such documents ire properly maintained and
controlled so that only appropriate revisions are implemented.
The Configuration Management program provides for an independent second
engineering review for engineering documents, and authorization basis change packages and
documentation potentially aecting safety analysis. Management review of authorization basis
changes, complex changes and modifications, and other issues affecting the safety analysis is
also provided. Management reviews of safety significant issues primarily focus responsible
management attention on safety issues, such as unreviewed safety questions, criticality controls,
modifications of equipment important to safety, and authorization basis modifications. These
reviews ensure adequacy of work authorization and documentation affecting the safe operation
of the Building 99 1 Complex.
Engineering supports configuration management through integration of fire protection,
safety and industrial hygiene, nuclear safety and criticality safety, environmental protection and
waste management, and radiation protection safety requirements into the development of new
designs and design modifications, as appropriate. Engineekg procedures ensure that changes or
modifications within the Building 991 Complex are accomplished according to applicable codes,
regulations, and standards. Each change that potentially affects a safety SSC receives review
through the unreviewed safety question determination (USQD) process. The program maintains
the authorization basis by providing for the control of documentation, review, and approval of
proposed complex modifications and interfacing with other SMPs.
The Configuration Management program is implemented by the Design Process
Requirements (Ref. 11) and Site Design Document ConiroZ (Ref- 12) procedures of the Conduct
of EngineeringMamral (Ref- 13).
3.5 CRITICALITY SAFETY
The Criticality Safety program for this building establishes criticality safety controls for
building activities involving fissionable material. This program includes the following
processes: to develop criticality safety controls (engineered and/or administrative); to monitor
compliance status with established controls (including infraction investigation and reporting);
and to maintain and control distribution of technical documents. The program ensures that
Criticality Safety approves criticality safety controls, either through new evaluations or the
Criticality Safety Limit Examination Program, for all activities involving the storage, relocation,
and/or processing of fissionable material. Major features of the program include engineering
design reviews; application of double-contingency principles; establishment of criticality safety
controls (e.g., nuclear criticality safety limits, procedures, posting); testing; surveillances;
training; and periodic program reviews.
