1.
Provide a list of' equipment within the scope of 10 CFR 50.49 that is located in the containment lower compartment area.
2.
Provide the qualification pressure and temperature test profiles (in the
]
form of curves for the equipment listed in Item 1 above. Do these environmental q)ualification (EQ) test profiles for accident and t
post-accident conditions.for each piece'of equipment listed in Item 1 above envelope the revised EQ accident and post-accident temperature /
j 5
pressure profiles?
If not, identify and provide justification for each case in which the EQ test profile does not envelope the revised accident i
and post-accident profiles. Justification involving the accident portion of the profiles should include information other than Arrhenius methodology.
i t
3.
Discuss how historical containment temperature data is used to l
demonstrate that the effect of the proposed temperature increase would not reduce the qualified life of components.
4.
In your analysis, one conclusion is that the design temperature of 120*F is maintained with adequate margin based on Arrhenius.
Provide a discussion to explain what is meant by adequate margin.
