satisfy an ITAAC. DCD Tier 2 and Reg Guide 1.68 tests should be examined and tests elevated to ITAAC as necessary. 4. If an ITAAC test is not normally done as part of a pre-operational test, the test methodology should be in Tier 1 or added to the DCD Tier 2 Section 14.2. Any supporting design or analysis issues should be put in the appropriate sections of Tier 2. Reference to the ITAAC may be included in Tier 2. Reference should not be made from Tier 1 to Tier 2 because this effectively makes Tier 2 part of Tier 1. 5. Use of the Terms "Test" and "Type Test" in the ITA should be consistent with the Tier 1 Definitions. Alternatively, testing may be classified as "Vendor", "Manufacturer", or "Shop" to make clear what type of test is intended. 6. If an analysis is required in the ITAAC, then the analysis or at least the outline of the analysis should be prepared and that will be put in the ITAAC or the appropriate section of the DCD Tier 2. The DCD Tier 2 may reference the ITAAC. 7. ITAAC column 2 should identify the component, division, or system that the inspection, test, and/or analysis verifies. 8. Refer only to inspections, not "visual" inspections. DRAFT Rev. 0 - April 1996 14.3-48 9. Numerical values, where appropriate, should be specified in the third column, acceptance criteria. 10. The ITAAC should be consistent in the use of present or future tense. 11. "Division" should be used instead of train, loop, or subsystem (unless it is a subsystem). 12. "Tier 1" and "Tier 2" should not be used in the ITAAC. 13. Avoid clarifying phrases in the ITAAC. 14. The correct system name should be used consistently. III. REVIEWER CHECK LISTS The following check lists are provided to assists the reviewer in the review of the fluid systems Design Descriptions, Figures, and ITAAC. As discussed before, the level of detail in any particular Design description, Figure, or ITAAC should be proportional to the safety significance of the SSC being reviewed. Therefore, all items shown
