Comparing the dispositions relevant for the matter in INFCIRC/153, Corrected and in INFCIRC/435 (15), he shows that when it comes to nuclear propulsion, the language in the Quadripartite Agreement is more specific and detailed, as it makes it very clear that 'special safeguards procedures' (the codeword for non-application of safeguards to nuclear material in NPMA) would apply "only while the nuclear material is used for nuclear propulsion or in the operation of any vehicle, including submarines and prototypes, or in such other non-proscribed nuclear activity as agreed between the State Party and the Agency" (IAEA 1994a, [section] 13, [b]; emphasis added).
