抜粋

To examine electrical insulation behavior of cables under severe accident environmental conditions, safety-related low voltage cables used as severe accident management equipment were subjected to two tests that simulated two environments: 1) at 155 oC, which is the simulated highest assumed temperature when proper accident management measures are taken, 2) at 200 oC, which is the maximum durable temperature of a primary containment vessel. In addition, electrical insulation resistance was measured for the cables during steam exposure in the two tests. As a result, all the cables passed the acceptance criteria of the tests. The minimum volume resistivity of the cables during the test at 155 oC was around 108 Ωm, confirming that the cables have a sufficient insulation performance. On the other hand, the minimum volume resistivity during the severer test at 200 oC was around 105 Ωm due to the increase in leak current.
