Provide technical justification that shows how operation at lower flow rates equates to the ability to operate at design flow rates. Also, discuss how the limiting acceptance criteria at the proposed lower flow rates relate to operations at the higher flow rates.
5.
Provide a basis for relief in accordance with 10 CFR 50.55a(a)(3)(ii) to show that compliance with the American Society of Mechanical Engineers Operating and Maintenance Code required testing would result in hardship or unusual difficultly with out a compensating increase in the level of quality and safety specifically in regards to installing temporary or permanent modifications needed to perform the comprehensive pump test.
