Instructions This checklist supplements PI-MP3-03 and shall be used to document the electrical design review process for system modifications. Application and use of this checklist shall be as follows:
J
- 1. When the need for a electrical design review is identified by the modification screening checklist (CK-MP3-03-02), the Verifier shall implement this check to verify that electrical system design aspects have been properly addressed in the modification.
- 2. The Verifier shall review each attribute listed in the checklist and shall determine whether the attribute has been properly addressed or is not applicable. The determination shall be documented by checking the appropriate column in the checklist.
- 3. For all "Yes" and "No" responses, the Verifier shall assign a sequential comment number and shall describe the basis for the response on the comment sheet included in this checklist.
Comments may also be provide for "N/A" responses.
- 4. When all attributes have been reviewed, the Verifier shall sign and date the cover sheet
- 5. The Lead Verifier shall indicate his concurrence that the electrical system review has been completed by signing and dating the cover sheet.
The system designation and modification number shall be entered on all sheets of the completed checklist. Pages shall be sequentially numbered. It shall be acceptable to add insert pages numbered as I A, IB,2A, etc.
