ULTIf)ATE CAPACITY ANALYSES OF ICE CONDENSER AND liARV III CONTAINHENTS Detailed analyses are to be performed to assess the effect on containment integrity of a potential hydrogen burn.
Ultimate capacity of the containment should be evaluated using a finite element model.
Uniform static pressure capability should be calculated.
Dynamic local and overall pressure capability should also be assessed.
Based on the actual material strength variations indicated by mill test certificates and other uncertainities, the mean, an estimate of 'disperson, and lower and upper bounds of the containment capacity should be established.
The details of the analyses and the results should be submitted in report form.
The following information should be readily identifiable in the report:
1.
Design pressure; 2.
Calculated static pressure retaining capacity; 3.
Calculated dynamic pressure strength considering appropriate pressure time histories; 4.
The associated failure modes (axisymmetric burst-pressure,
- buckling, rebar yielding, penetration failure, closure failure, or others);
5.
The criteria governing the original design and the criteria used to establish failure; 6.
Analysis details and general results; and 7.
Appropriate engineering drawings adequate to allow verification of modeling and evaluation of analyses employed for penetrations.
