Basic Design Documents
Detailed Design Documents
Design Inputs
• Commitments in the Technical
Annexure at the time of contract
• Reference Plant Relevant
documents/parameters
• Relevant Codes and Standards
• Issues raised in the review process
of PSAR/FSAR of operating plants
• Feedbacks from the operating plants
• Regulatory requirement if any

Review Process
Coordination Directorate prepare a check list for review
• Responsible engineer review the document and produce comments
• Comments are further reviewed by a senior engineer of the relevant
discipline as per check list
• After finalizing the comments at senior engineer level comments are
forwarded to Manager of the relevant division
• Comments are reviewed at director level
• Forwarded to coordination Directorate
• Further reviewed and forwarded to CZEC or dropped

Review of Detailed Design Documents
Review inputs:
• Commitments in the Technical Annexure at the time of contract
• Reference Plant Relevant documents/parameters
• Relevant Codes and Standards
• Issues raised in the review process of PSAR/FSAR of operating
plants
• Feedbacks from the operating plants
• Regulatory requirement if any
• To ensure the implementation of basic design review comments

WHY?
Engineering support is essential to maintain design and configuration so as:
• To ensure the safe operation of NPPs • To maximize their availability and productivity
AREAS IN WHICH TECHNICAL SUPPORT IS PROVIDED
Responsible Designer support in various areas, including
• Specific research • Engineering services • Development of technical improvements • Analysis and testing
ASSISTANCE TO AN NPP OPERATING ORGANIZATION ON DESIGN DECISIONS
• "R & D " and designer can provide technical support to “services” • Feedback from the "service " are provided to "R & D" and "designer" to
enhance plant safety performance.
