INTRODUCTION

DRAWINGS REVIEWS

Requirements

Note: This program is intended to assist the line PA. It does not change the responsibility or authority of either the line PA or, ultimately, the line supervisor.

PAs in the Design Group (2990) shall certify compliance with the review requirement for pressure systems and component drawings:generated by the Design Group (2990) by affixing a signed Pressure Data Stamp on the original drawing. This stamp constitutes a design specification. Signature authority is limited to SNL line PAs or Safety Engineering.

Note: The Supply Chain Management Center (10200) cannot process pressure system drawings without the proper signatures.

Guidance

If a Member of the Workforce determines that the Pressure Safety Drawing Review Program should not be applied, this requirement will be waived on written concurrence for either the:

• Line PA.
• Manager.
• Safety engineering representative.

PAs in the Design Group (2990) typically should include the following actions in their reviews of pressure systems drawings:

• Examine for compliance with this document.
• Identify the current line organization PA to the customer.
• Inform the line PA of the program in the line PA's area.

  Note: The Design Group (2990) has written a tutorial computer program defining total energy levels for the four gases listed in the PSM. This program is available to all PAs and engineering consultants. Members of the Workforce are encouraged to use this program in the design of pressure systems.

• Recommend using ASME Code­stamped vessels when possible and ASME design procedures when Code­stamped vessels are not available or are inappropriate.
• Furnish ASME Code information, specifications for ANSI standards, welding specifications, and drawing note references as needed.
• Advise about Sandia expertise for materials, stress, pressure testing capabilities, welding, Safety Organization, etc.
• Urge application of and compliance with the PSM.

PAs in the Design Group (2990) will generally not review the following pressure systems drawings:

• WR components
• Commercial components

  Note: Procure from approved Just-In-Time source.

• Drawings not prepared by the Design Group
• An engineering review of the design.

  Note: The review by PAs in the Design Group (2990) is for safety compliance only.

  Note: The Design Group supports an in-house training program and ASME-sponsored classes for their reviewers so the reviewer can help with design review if asked. However, responsibility for safe design and operation always remains with the line PA and, ultimately, the line supervisor. The Design Group will make design recommendations within their limits of expertise upon request.
