Similarly, breaks should be assumed to occur at any intermediate locations between terminal ends of piping runs or branch runs that exhibit stress intensities above conservatively derived limits based on the stress levels actually existing in the fluid system piping. The 'limits selected on this basis are elastically USAEC REGULATORY GUIDES Copies of published guides may be obtained by request indicating the divisions desired to the U.S. Atomic Energy Commission, Washington, D.C. 20545, Regulatory Guides are issued to describe and make available to the public Attention: Director of Regulatory Standards.
