This letter report provides the results of a comparison of the Mark II containment response to the lead plant 4T Bounding Loads Report chugging load specification with that for an improved load specification based on an impulse chug source at the vent. This com-parison was done for a pre-stress concrete, reinforced concrete, and steel containment to show that the 4T bounding load specification is conservative and suitable for lead plant application. In addition, this study introduces aspects of'mprovement in this load definition for consideration in subsequent plant evaluations.
