Question Instructions and Guidance YES NO N/A 1
Do assumptions have sufficient documented rationale?
All Assumptions should be stated in clear terms with enough justification to confirm that the assumption is conservative:
For example, 1) the exact value of a particular parameter may not be known or that parameter may be known to vary over the range of conditions covered by the Calculation. It is appropriate to represent or bound the parameter with an assumed value.
- 2) The predicted performance of a specific piece of equipment in lieu of actual test data. It is appropriate to use the documented opinion/position of a recognized expert on that equipment to represent predicted equipment performance.
Consideration should also be given as to any qualification testing that may be needed to validate the Assumptions. Ask yourself, would you provide more justification if you were performing this analysis? If yes, the rationale is likely incomplete.
X 2
Are assumptions compatible with the way the plant is operated and with the licensing basis?
Ensure the documentation for source and rationale for the assumption supports the way the plant is currently or will be operated post change and they are not in conflict with any design parameters. If the Analysis purpose is to establish a new licensing basis, this question can be answered yes, if the assumption supports that new basis.

Title:
Post Fire Safe Shutdown (PFSSD) Analysis Wolf Creek document #: XX-E-013-004-CN005 Revision #: N/A ECDE: Enercon No.
Question Instructions and Guidance YES NO N/A 3
Do all unverified assumptions have a tracking and closure mechanism in place?
If there are unverified assumptions without a tracking mechanism indicated, then create the tracking item either through an ATI or a work order attached to the implementing WO. Due dates for these actions need to support verification prior to the analysis becoming operational or the resultant plant change being op authorized.
X 4
Do the design inputs have sufficient rationale?
The origin of the input, or the source should be identified and be readily retrievable within WCNOC's documentation system.
If not, then the source should be attached to the analysis. Ask yourself, would you provide more justification if you were performing this analysis? If yes, the rationale is likely incomplete.
X 5
Are design inputs correct and reasonable with critical parameters identified, if appropriate?
The expectation is that an WCNOC Engineer should be able to clearly understand which input parameters are critical to the outcome of the analysis. That is, what is the impact of a change in the parameter to the results of the analysis? If the impact is large, then that parameter is critical.
X 6
Are design inputs compatible with the way the plant is operated and with the licensing basis?
Ensure the documentation for source and rationale for the inputs supports the way the plant is currently or will be operated post change and they are not in conflict with any design parameters.
X 7
Are Engineering Judgments clearly documented and justified?
Ask yourself, would you provide more justification if you were performing this analysis? If yes, the rationale is likely incomplete.

Title:

Question Instructions and Guidance YES NO N/A 8
Are Engineering Judgments compatible with the way the plant is operated and with the licensing basis?
Ensure the justification for the engineering judgment supports the way the plant is currently or will be operated post change and is not in conflict with any design parameters.
If the Analysis purpose is to establish a new licensing basis, then this question can be answered yes, if the judgment supports that new basis.
X 9
Do the results and conclusions satisfy the purpose and objective of the Design Analysis?
Why was the analysis being performed?
Does the stated purpose match the expectation from WCNOC on the proposed application of the results? If yes, then the analysis meets the needs of the contract.
X 10 Are the results and conclusions compatible with the way the plant is operated and with the licensing basis?
Make sure that the results support the USAR defined system design and operating conditions, or they support a proposed change to those conditions. If the analysis supports a change, are all of the other changing documents included on the cover sheet as impacted documents?
X 11 Have any limitations on the use of the results been identified and transmitted to the appropriate organizations?
Does the analysis support a temporary condition or procedure change? Make sure that any other documents needing to be updated are included and clearly delineated in the design analysis. Make sure that the cover sheet includes the other documents where the results of this analysis provide the input.
X 12 Have margin impacts been identified and documented appropriately for any negative impacts.
Make sure that the impacts to margin are clearly shown within the body of the analysis.
If the analysis results in reduced margins ensure that this has been appropriately dispositioned in the EC being used to issue the analysis.

Title:

Question Instructions and Guidance YES NO N/A 13 Does the Design Analysis include the applicable design basis documentation?
Are there sufficient documents included to support the sources of input, and other reference material that is not readily retrievable in WCNOC controlled Documents?
X 14 Have all affected design analyses been documented on the Affected Documents List (ADL) for the associated ConfiQuration Change?
Determine if sufficient searches have been performed to identify any related analyses that need to be revised along with the base analysis. It may be necessary to perform some basic searches to validate this.
X 15 Do the sources of inputs and analysis methodology used meet committed technical and regulatory requirements?
Compare any referenced codes and standards to the current design basis and ensure that any differences are reconciled. If the input sources or analysis methodology are based on an out-of-date methodology or code, additional reconciliation may be required if the site has since committed to a more recent code X
16 Have vendor supporting technical documents and references (including GE DRFs) been reviewed when necessary?
Based on the risk assessment performed during the pre-job brief for the analysis, ensure that sufficient reviews of any supporting documents not provided with the final analysis are performed.
X 17 Does the design include any digital assets? If so, does it adequately address digital and cyber security requirements?
Ensure the design addresses and meets digital and cyber security requirements. Refer to AP 15D-008 and contact the Cyber Security Group to perform additional reviews prior to approval. The CSAT is required to review modifications impacting Cyber Security.
