opriately considered. This uncertainty could reduce the level of assurance and potentially invalidate a conclusion that operators can perform the action reliably within the time available. For complex situations and for actions with limited margin, such as less than 30 minutes between time available and time required, a more focused staff review will be performed. BTP 7-19-20 Draft Revision 7 – August 2015 4.7 Justification for Not Correcting Specific Vulnerabilities If any identified vulnerabilities are not addressed by design modification, refined analyses, or provision of alternate trip, initiation, or mitigation capability, justification should be provided.
