介绍了~(60)Co源的灌水浸泡检漏法。考虑到衰变热对检漏的影响,理论估算了贮源铅罐内的温度。计算与实测结果表明,当用灌水浸泡法检漏时,向贮源铅罐内灌注室温水,不会对辐射源包壳带来破坏性热冲击。 Introduced the ~ (60) Co source irrigation immersion leak detection method. Taking into account the influence of decay heat on leak detection, the temperature in the source storage tank is theoretically estimated. The calculation and the measured results show that, when leaking with water immersion method, the room temperature lead water tank is filled with room temperature water, which will not bring devastating thermal shock to the radiation source cladding.
