NUREG-1537, Part 2 - NRC

The reviewer should evaluate the following:
ENGINEED SAFT FEATuRES
* Design bases and functional description of the required mitigative features
-of the containment, derived from the accident scenarios.
* Drawings, schematic diagrams, and tables of important design and
operating parameters and specifications for the containment, including
- volume and overpressure capability
- seals, gaskets, filters, and penetrations (e.g., electrical,
experimental, air, and water)
necessary ESF equipment included as part of the containment
- fabrication specifications for essential and safety-related
components.
* Discussion and analyses, keyed to drawings, of how the structure provides
the necessary containment presented in Chapter 13, with cross reference to
other chapters for discussion of normal operation (such as Chapters 4 and
11), as necessary.
* Description of control and safety instrumentation, including the locations
and functions of sensors, readout devices, monitors, and isolation
components, as applicable. (Design features should ensure operability in
the environment created by the accident.)
* Discussion of the shielding protection factors provided for direct radiation
and the required limitations on leakage or release of contained effluents to
the environment.
* Conditions under which operability is required, and the surveillance
methods and intervals in the technical specifications that ensure operability
and'availabiityofthe containrent, when required.
Acceptance Ceria
The acceptance criteria for the information on the containment ESF include the
following:
* The need for a containment ESF should be properly identified. To be
considered an ESF, design features should exist to mitigate the
consequences of specific accident scenarios.
