“…Koenig and Subramanian reviewed the tests aimed at investigating performance of mechanical penetrations of PCVs under severe accident environments. They concluded that degradation of the seal is accompanied by a loss of metal-to-metal contact at the sealing surface [Koenig, L. N. and Subramanian, C. V., 1987].…”

“…Regarding experiments on failure criteria of compounds used for seals and gaskets on PCV boundaries, Koenig and Subramanian overviewed the experiments regarding the performance of penetration subjected to over-pressure and over-temperature environments [Koenig, L. N. and Subramanian, C. V., 1987]. Wensel reported degradation of elastomeric o-ring seals under thermal and radiative circumstances [Wensel, R. G., 1977], Wensel, R. G., and Cotnam, B. M., 1978].…”

Experiments regarding failures of primary containment vessels (PCVs) are reviewed and remained issues to be investigated in the future are discussed.Experiments are categorized as those relating to criteria of PCV failures and to FP releases through breaches on PCV boundaries. In the experiments categorized as those relating to criteria of PCV failures, experiments with full-scale, scale models, and compounds used for sealing are surveyed. Experiments relating to an amount of radioactive fission products (FPs) trapped at breaches on PCV boundaries are also reviewed. As remained issues to be investigated in the future, two items are pointed out: Evaluating degradation behavior of PCV boundaries exposed to temperature and pressure from the failure onset criteria to far above them, and evaluating an amount of FPs trapped at breaches on PCV boundaries.
