Request for Additional Information - Calvert Cliffs Unit 2 Cycle 19 Fuel Rod Revision 1 Thermal Mechanical Inputs Page 1-1 1.0 Introduction The Nuclear Regulatory Commission (NRC) is in the process of reviewing a Licensing Amendment Request (LAR) submitted by Calvert Cliffs Nuclear Power Plant in support of their

/

plan to transition from Westinghouse fuel to the AREVA Advanced CE-14 HTP fuel for Calvert Cliffs Units 1 and 2. In Reference 1, the NRC has requested additional information in order to complete their review of the LAR. The additional information requested consists of the AREVA Advanced CE-14 HTP fuel rod design parameters, coolant conditions, and power history inputs.

The information requested by the NRC is listed in Table 1-1 along with a cross referencing scheme that shows the location of the pertinent information within this document.

Request for Additional Information - Calvert Cliffs Unit 2 Cycle 19 Fuel Rod Revision 1 Thermal Mechanical Inputs Page 2-1 2.0 Requested Data 2.1 Rod PowerHistory Data AREVA does not use a composite, bounding operating envelope to perform its fuel performance analyses using the RODEX2 code (References 2 and 3). Instead, AREVA's methodology consists of using a set of cycle-specific power histories for each individual fuel rod type in core.

These cycle-specific histories are based on upper-bound predicted cycle lengths. These histories are then adjusted according to the NRC-approved method to assure that the Technical Specification limits are protected. These analyses are repeated every cycle to assure that continued operation is within the approved specified acceptable fuel design limits.

A distinct fuel rod type is determined based on whether it is a U0 2 or Gadolinia bearing rod and based on the different fuel columns within the rod. The AREVA fuel batch to be introduced into Calvert Cliffs Unit 2 Cycle 19 will feature five different fuel rod types - 4.88% enriched U0 2 rod, 4.34% enriched U0 2 rod, 2 wt% Gadolinia rod with 4.40% U0 2, 6 wt% Gadolinia rod with 3.42%

U0 2 , and 8 wt% Gadolinia rod with 2.93% U0 2. All of these rod types will use 2.00% U0 2 top and bottom axial blankets. Design histories are selected for each of these rod types from the most limiting (highest power and burnup) projected fuel rod histories in accordance with the criteria in Reference 4. The selection encompasses the most limiting histories for each mode of operation in the core.

[b.]

Together this set of histories represents the "design power histories." During steady-state operation, either a cycle average axial profile is used or optionally, several axial profiles through the cycle may be used. The power histories are then adjusted to assure that the Technical Specification peaking limits are protected.

Due to the nature of AREVA's NRC-approved methodology, a large set of design histories are analyzed every reload cycle for fuel performance verification. This document will present the most limiting U0 2 rod history and the most limiting Gadolinia bearing rod history, both chosen on the basis of the highest predicted fuel rod internal pressure for the U0 2 and the Gadolinia AREVA NP Inc.

The other power histories are available if requested. These selected histories are plotted in Figure 2-1 and are presented in tabular fashion in Appendix A of this document.

Note that these power histories depict the 'physics' LHGR values and do not consider any reduction in power due to fraction of heat not generated in the fuel.

For gas pressure calculations, the, histories shown in Figure 2-1 are adjusted with various factors as per the requirements in Reference 4. A bias is established based on the

is applied to all [b.] This bias represents the neutronic calculational uncertainty.

Additionally, for gas pressure calculations, periodic transients are added to bound the gas release effects of potential transients as described in Section 2.2.

2.2 Axial PowerDistributionData AREVA typically uses a 12-noded axial model for performing its fuel rod thermal-mechanical analyses. For each design history file, the normalized steady-state axial power distributions are defined at each time step along with the rod average power and the time in hours. These design history files are in a special format that can be read by the RODEX2-based code system. The steady-state axial power distributions at each time step have been extracted from the limiting design history files for U0 2 and Gadolinia bearing fuel rods and are presented in Appendix B in a tabular format along with the axial elevation of each node.

For gas pressure calculations, the axial profiles are peaked every [b.] with a duration of

The transient axial profiles used for the Calvert Cliffs Unit 2 Cycle 19 analysis are shown in Appendix B.

2.3 Advanced CE-14 HTP Fuel Rod Design Parametersand Cycle 19 Operating.

Conditions Table 2-1 contains the specific Advanced CE-14 HTP fuel rod design parameters and Cycle 19 operating conditions that were requested by the NRC in Reference 1. Some of these requested parameters are not directly used by AREVA in their fuel performance input file but are required to be maintained through inspection and qualification per the fuel product design specifications for each reload batch. In addition, Table 2-2 shows selected supplemental parameters that are used by AREVA for fuel performance analysis. Several of these input parameters are biased by AREVA's fuel performance code system in accordance with NRC-approved practice.
