r Power Operations (INPO), and ANSI/ANS standards. Some examples of such guidance are given here even though they don’t explicitly address the situation we are concerned with here. Hence, applicants would need to establish (or commit to establish) appropriate administrative controls. An example of addressing task postponement in the face of more important tasks is provided in ANSI/ANS-3.2-2012. Section 3.5.1, Procedure Adherence, states in part: In the event of an emergency not covered by an approved procedure or an emergency not following the path upon which the approved procedure is based, operations personnel shall be instructed to take action so as to protect public health and safety and to minimize personnel injury and damage to the facility. This can be interpreted as allowing the postponing of less important tasks, that impacts the staffing needed to respond to events, but it doesn’t require NPPs to have such specific words in their administrative controls. NRC Regulatory Guide 1.33 endorses ANSI/ANS-3.2-2012. Two key INPO documents related to plant operations are as follows (identified here for information only): • INPO 10-004 Principles for a Strong Plant Operational Focus, June 2013, Revision 1. 18.0-38 Draft Revision 3 – July 2015 • INPO 01-002 Guidelines for the Conduct of Operations at Nuclear Power Stations, May 2001 INPO 10-004 provides the general practices needed to attain high-levels of operational safety and reliability at NPPs. It emphasizes the importance of plant operations. INPO 01-002 provides guidelines for achieving excellence in the various aspects of plant operations. One aspect noted is ensuring that administrative duties assigned to operators do not detract from their ability to safely operate the plant. b. Applicants should identify their assumptions regarding the status of these excluded independent actions, e.g., “we have not included drug testing actions in our analysis because we assume such actions will not interfere
