NUREG-1537, Part 2 - NRC

CHAPTRS
acceptable radiological dose consequence limits derived from the accident
analyses. The radiological consequences from the contaminated coolant
should be discussed in Chapter 11 and summarized in this section of the
SAR. Necessary surveillance provisions should be included in the technical
specifications.
The applicant should identify operational limits, design parameters, and
surveillances to be included in the technical specifications.
Review Procedures
The reviewer should compare the functional design and the operating
characteristics of the primary coolant system with the bases for the design
presented in this and other relevant chapters of the SARI The system design
should meet the appropriate acceptance criteria presented above considering the
specific facility design under review.
Evaluation Findings
This section of the SAR should contain sufficient information to support the
following types of conclusions, which will be included in the staffs safety
evaluation report:
* The primary coolant system is designed in accordance with the design
bases derived from all relevant analyses in the SAR
* Design features of the primary coolant system and components give
reasonable assurance of fuel integrity under all possible reactor conditions.
The system is designed to remove sufficient fission heat from the fuel to
allow all licensed operations without exceeding the established limiting
safety system settings that are included in the technical specifications.
* Designs and locations of primary coolant system components have been
specifically selected to avoid coolant loss that could lead to fuel failure,
uncontrolled release of excessive radioactivity, or damage to safety systems
or experiments. Heavy water systems are designed to quickly detect
leakage and prevent the release of heavy water to the environment. (If an
emergency core cooling system is required to prevent a loss offuel
integrity, it is evaluated in connection with the review of the engineered
safetyfeatures.)
(For reactors licensed to operate withforced-convection coolant flow)
The primary coolant system is designed to convert in a passive or fail-safe
method, to natural-convection flow sufficient to avoid loss of fuel integrity.
