lbb

Leak before break ( LBB) is an important concept for assessing pressure vessels and nuclear equipment.

破前漏（简称LBB）是压力容器、核电站设备结构设计与评价中的一个重要准则。

With the more and more stringent safety requirements for high pressure vessels and nuclear energy equipment, the importance of LBB rule is increasing.

随着人们对高压容器特别是核能设备安全性要求的提高，先漏后爆准则的重要性不断增加。

Three phenotypes ( Est-lAA, Est-lAB and Est-lBB ) were detected.

Est -1 位点遗传多样性指数为 0.4790 .

The affection of fatigue and creep to the crack growth must be considered when LBB is applied on the nuclear pipes in the high temperature reactors ( as fast reactor) beyond the creep temperature.

对于在蠕变温度以上高温堆（如快堆）的核级管道，运用LBB分析时应该考虑疲劳和蠕变对裂纹扩展的影响。
