responsible for the design (i.e., neither the performer or his immediate super- visor). In exceptional circumstances, the designer's immediate supervisor can perform the verification provided: (1) The supervisor is the only technically qualified individual. (2) The need is individually documented and approved in advance by the supervisor's management. (3) QA audits cover frequency and effectiveness of use of supervisors as design verifiers to guard against abuse. b. Design verification, if other than by qualification testing of a prototype or lead production unit, is completed prior to release for procurement, manufacturing, construction or to another organization for use in other design activities. In those cases where this timing cannot be met, the design verifi- cation may be deferred, providing that the justification for this action is documented and the unverified portion of the design output document and all design output documents, based on the unverified data, are appropriately identified and con- trolled. Construction site activities associated with a design or design change should not proceed without verification past the point where the installation would become irreversible (i.e., require extensive demolition and rework). In all cases, the design verification should be complete prior to fuel load for a plant under construction, or in the case of an operating plant, prior to-relying upon the component, system, or structure to perform its function. c. Procedural control is established for design documents that reflect the commitments of the SAR; this control differentiates between documents that receive formal design verification by 17.1-12 Rev. 2 - July 1981 interdisciplinary or multi-organizational teams.and those which can be reviewed by a single individual (a signature and date is acceptable documentation for personnel certification). Design documents subject to procedural control include, but are not limited to, specifications, calculations, computer
