CHAPTER4
Review Procedures
The reviewer should confirm that the design bases describe the requirements for
the tank and that the detailed design is consistent with the design bases and
acceptance criteria for the tank.
Evaluation Findings
This section of the SAR should contain sufficient information to support the
following types of conclusions, which will appear in the staffs safety evaluation
report:
* The tank system can withstand all anticipated mechanical and hydraulic
forces and stresses to prevent loss of integrity which could lead to a loss of
coolant or other malfunction that could interfere with safe reactor
operation or shutdown.
* The penetrations and attachments to the tank are designed to ensure safe
reactor operation. Safety and design considerations of any penetrations
below the water level include analyses of potential malfunction and loss of
coolant. The applicant discusses credible loss-of-coolant scenarios in
Chapter 13, "Accident Analyses."
* The construction materials, treatment, and methods of attaching
penetrations and components are designed to prevent chemical interactions
among the tank, the coolant, and other components.
* The outer surfaces of the tank are designed and treated to avoid corrosion
in locations that are inaccessible for the life of the tank. Tank surfaces will
be inspected in accessible locations.
* The applicant has considered the possibility that primary coolant may leak
into unrestricted areas, including ground water, and has included
precautions to avoid the uncontrolled release of radioactive material.
* The design considerations include the shape and dimensions of the tank to
ensure sufficient radiation shielding to protect personnel and components.
Exposures have been analyzed, and acceptable shielding factors are
included in the tank design.
* The applicant has justified appropriate limiting conditions for operation and
surveillance requirements for the tank and included them in the technical
specifications.
