design, | No. Resp. Issue Description Status RAI No. PSEG Response The software development process includes a series of technical design reviews and baseline reviews. At the end of each of these reviews, a review report and a scorecard will be issued by the review chair. The review report summarizes the results of the review. | ||
The scorecard evaluates the content of the review material and the performance of the design team based on pre-established criteria also known as metrics, e.g., Did the design team resolve action items assigned at previous reviews, or are acceptable plans in place? A successful review will require a passing grade of 75%. However, any grade below 90% would result in action items to correct the deficiency in the design or in the compliance with the design process. Condition reports will be issued in accordance with GEH problem reporting procedure should a design fail any of the reviews. | |||

At the end of each of these reviews, a review report and a scorecard will be issued by the review chair. The review report summarizes the results of the review.
The scorecard evaluates the content of the review material and the performance of the design team based on pre-established criteria also known as metrics, e.g., Did the design team resolve action items assigned at previous reviews, or are acceptable plans in place? A successful review will require a passing grade of 75%. However, any grade below 90% would result in action items to correct the deficiency in the design or in the compliance with the design process. Condition reports will be issued in accordance with GEH problem reporting procedure should a design fail any of the reviews.

This Each of the BTP 7-19 criteria are appendix does not include analysis for addressed in Appendix I. The criteria that the potential of the PRNMS to adversely directly address the potential of the affect other echelons of defense (e.g. the PRNMS to adversely affect other control echelon). Please describe how echelons of defense may be found in other echelons of defense could not be Table 4.2. For example, The discussion adversely influenced by interfaces with about the potential for PRNMS to the PRNMS. adversely affect the control echelon is addressed in Criterion (3).

Verification and Validation Engineer and the System Safety Analysis Engineer and
- Prepare equipment qualification defines roles and responsibilities for test plans and procedures these positions in Sections 2.2.2 & 2.2.3
- Perform equipment qualification respectively. The Hope Creek NUMAC testing/analysis and document the System Management Plan however, results identifies a third position of System Test
- Summarize equipment and Qualification Engineer as a member qualification results in a of the IVV team (See Figure 2-1 and qualification summary report Section 2.2.4 of Appendix E). The responsibilities for this third position are The SyIVVP also states that the IVV team not defined in either Appendix D or reports to the Chief Engineers Office E. The NRC staff requests information of (CEO) and that the CEO may draw upon the roles and responsibilities for the Test subject matter experts from anywhere and Qualification Engineer be provided to within the GEH engineering support the staffs determination of population. GEH Engineering has a team NUMAC V&V effectiveness. of Test and Qualification Engineers who are responsible for the testing and qualification of all types of equipment, including mechanical and analog devices. Members of this team are logical candidates for performing the test and qualification of the PRNM equipment for Hope Creek. However, the candidate must be approved by the CEO. Therefore, the role and responsibilities of the Test and Qualification Engineer are as stated in the three bullets above from the SyIVVP.
