hould focus on the HSIs that are relevant to the modification. HSIs for temporary configurations and situations where both old and new HSIs are left in place should be evaluated for their potential to negatively impact performance. 18.0-16 Revision 2 - March 2007 4. Integrated System Validation. The applicant should perform an integrated system validation for all modifications that may (1) change personnel tasks; (2) change task demands, such as by changing task dynamics, complexity, or workload; or (3) interact with or affect HSIs and procedures in ways that may degrade performance. Integrated system validation may not be needed when a modification results in minor changes to personnel tasks such that they may reasonably be expected to have little or no overall effect on workload and the likelihood of error. The staff should verify that the applicant validates that the functions and tasks allocated to plant personnel can be accomplished effectively when the integrated design is implemented. The applicant’s test objectives and scenarios should be developed to address aspects of performance that are affected by the modification design, including personnel functions and tasks affected by the modification. B.9 Design Implementation The objective of this review is to verify that the applicant’s implementation of plant changes considers the effect on personnel performance and provides the necessary support for safety of operations. The applicant’s design implementation should be evaluated in accordance with the review criteria of NUREG-0711. The following aspects of the design process should be addressed. 1. General Criteria. The staff's review should address whether the applicant has provided assurance that: C The reactor fuel is safely monitored during the shutdown time period while the physical modifications are being implemented in the control room. C Operations and maintenance crews are fully trained and qualified to operate and maintain the plant prior to
