Content:
tructure, system, and component (SSC) will not adversely affect any EDEFSS safety function. F. The consequences of a single active failure in a fuel oil system will not lead to a loss of more than one diesel generator. G. The design includes the capability to detect and control system leakage, including isolating system portions in the event of excessive leakage or component malfunction. H. A minimum of seven days supply of fuel oil for each diesel generator system is onsite to meet the engineered safety feature load requirements following a loss of offsite power and a design-basis accident (DBA). I. Adequate and acceptable sources of fuel oil are available, including the means of transporting and recharging the fuel storage tank, following a DBA to enable each redundant diesel generator system to supply uninterrupted emergency power for as long as required J. Instrumentation and control features permit operational testing of the system and assure that normal protective interlocks do not preclude engine operation during emergency conditions. K. Suitable precautions will prevent deleterious material from degrading the stored fuel and periodic tests will verify whether fuel degradation affects engine performance. L. Sufficient space permits inspection, cleaning, maintenance, and repair of the system. 9.5.4-3 Revision 3 - March 2007 2. Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC). For design certification (DC) and combined license (COL) reviews, the staff reviews the applicant's proposed ITAAC associated with the structures, systems, and components (SSCs) related to this SRP section in accordance with SRP Section 14.3, "Inspections, Tests, Analyses, and Acceptance Criteria." The staff recognizes that the review of ITAAC cannot be completed until after the rest of this portion of the application has been reviewed against acceptance criteria contained in this SRP section. Furthermore, the staff reviews the ITAAC to ensure that all SSCs in this area of
