EllCLDIURE 1 Independent Desic_n Review Attributes

! The concept of IDRs is based on a comprehensive ennminstion of the developant and leplementation reviewed to assess ofthethe design quality offor a sample design system of the facility being activities. The IDR should be a eultidfeciplinary review including, as e minimum, areas such en mechanical systass and components, electric power, civ11 and structural, and instrumente-tion and control. The primary focus is on en assessment of the implemented design control process for the ortpnization(s) parfoming design and engineer-ing services for the licensee ine"uding the architect engineer (A/E), nuclear system supp1fer (N555), vendor (s), consultant (s). contractor (s) and subcon-tractor (s).The system inenagement of the total desi A/E, #555, vendor (s), censultant(s). contractor (s)gn process

, and by the licensee.

subcontractors is evalu-ated.

.The process. evaluation starts with deveTopment of a logic or flow natuork of the design Each functional entity within the design organization should be identified. For each of these entities. internal and external design inter-feces which involve transmittel of design information should be specified, From this network, critical design eMas er areas with the least tolerance for error sticuld be 1dentified. Within each of the design entitles, the specific pro-cedures for the vartfication end innsmittal of design information should be tuviewed for confottence with the everall quality assurance program, and to identify specific weaknesses in the design process. Based on the results of the procedure mutew and the identification of critico) design stees, a l specific sample'should be mviewed in-depth.

The review should the following focus on desigr. work for a selected sample system (s) having characteristics:

(1) Essential to plant safety .

(2) Designed y the A/E (3) A cisarly defined design basis (4) Generally wpresentative of safety-related feature'; in other swetems
