ould focus on the HSIs that are relevant to the modification (as identified in NUREG-071 1). For modifications to plant systems that do not include modifications of the HSIs, task support verification should identify any hew defnands for monitorinrg-and cobitrol, and determine whether "they are adequately addressed by the existing HSI design. HSIs for temporary DRAFT Rev. 1 :- December 2002 18.0-11 configurations and situations where both old and new HSIs are left in place should be evaluated for their potential to negatively impact performance. 3. HFE Design Verification. HFE design verification should focus on the HSIs that are relevant to the modification (as identified in NUREG-071 1). 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. 4. Integrated System Validation-. The applicant should perform an integrated system validation for all modifications that may (as identified in NUREG-0711)-(1) change personnel tasks; (2)'chlange task demands, such as byy'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 ensure 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 aspecits of performance that are affected by the modification design, including personnel functions and tasks affected by the modification (as identified in NUREG 0711) B.9 Design Implementation The objective of this review is to ensure that the applicant's implementation of
