Content:
-water-cooled nuclear power reactors. To meet these objectives, the guide describes statistical methods related to product sampling that will ensure that this and other approved analytical models will adequately describe the effects of densification for each initial core and reload fuel quantity produced. The guide considers fuel pellets with Uranium dioxide, mixed oxide, or Gadolinium oxide. Pellets with dopants such as chromia or silicate are expected to behave similarly and the equations in the guide can be used. The NRC staff did not identify any technical or regulatory issues with the current version. The staff has reviewed the guide and has not identified any safety concerns or a need to revise it at this time 2. What is the impact on internal and external stakeholders of not updating the RG for the known issues, in terms of anticipated numbers of licensing and inspection activities over the next several years? As no technical or regulatory issues were identified, there is no impact to internal or external stakeholders resulting from these activities. 3. What is an estimate of the level of effort needed to address identified issues in terms of full-time equivalent (FTE) and contractor resources? As no technical or regulatory issues were identified, no resources are required. 4. Based on the answers to the questions above, what is the staff action for this guide (Reviewed with no issues identified, Reviewed with issues identified for future consideration, Revise, or Withdraw)? Reviewed with no issues identified. 5. Provide a conceptual plan and timeframe to address the issues identified during the review. No technical or regulatory issues were identified during the review. The staff currently is not planning to take any action on this guide. NOTE: This review was conducted in September 2015 and reflects the staff’s plans as of that date. These plans are tentative and are subject to change.
