NRC-HQ-60-15-C-0012 M0023 ATTACHMENT NO. 1 Additions to Section C.6 List of Services/Deliverables Task 11 - Pin Power Reconstruction (PPR) Method for PARCS Hexagonal Nodes in VVER Reactors The nodal methods used to perform the core solution do not directly provide the detailed fuel pin power information which can be important for the safety assessment of a core fuel loading. In most of the modern neutronics codes such as PARCS which employ advanced nodal methods, the pin power information is obtained through a pin power reconstruction or dehomogenization process. The terms reconstruction and dehomogenization arise from the fact that the neutron flux calculation performed in a nodal code is based on homogenized nodal cross sections so that the resulting intranodal flux distribution cannot reflect any local heterogeneity within an assembly. A reconstruction process is thus required to incorporate the actual heterogeneous structure of each assembly into the smoothly-varying intranodal flux distribution.

The pin power reconstruction process involves a fundamental assumption; that is, detailed pin-bypin distributions within an assembly can be estimated by the product of a global intranodal distribution and a local heterogeneous form function. The form function accounts for assembly heterogeneities caused by water holes, burnable absorber pins, enrichment zonings, etc., and it is generated for each fuel assembly type by a lattice physics code at the same time when the homogenized nodal cross sections are generated.

A polynomial function expansion method for the hexagonal geometry will be developed that is consistent with the pin power reconstruction method currently used for the cartesian geometry in PARCS. Similar to the cartesian geometry, the axial variations of the flux are rather smooth for hexagonal assemblies, so it is assumed that the radial and axial dependences of the intranodal flux are separable and the pin power reconstruction method deals primarily with a 2D problem.

The 2D intranodal flux distribution will be determined such that it is consistent with the neutron balance equation and it also satisfies the 2D neutron diffusion equation for the node. The pin power reconstruction capability will be developed and implemented for the current TPEN capability using full core, assembly centered geometry.

Summary of SubTasks and Deliverables Subtask 11.1: Derive and document the Hexagonal PPR equations that will be used for PARCS. The existing Hexagonal PPR method will be adapted to the existing TPEN nodal solver in the PARCS code system.

Deliverable for Subtask 11.1: Updated Draft Theory Manual - Chapter 7 of the Theory Manual will be updated with the adapted Hexagonal PPR method, specifically, the additional equation set to be solved.

The updated Theory Manual will be delivered to the COR 103 days after task commencement.

Subtask 11.2: Implement the adapted Hexagonal PPR kernel into the PARCS code system.

The adapted Hexagonal PPR kernel will be implemented in the PARCS code system. The Code system will include the PARCS source code, and any associated updates to the 3

NRC-HQ-60-15-C-0012 M0023 ATTACHMENT NO. 1 GenPMAXS source to support Hexagonal PPR to include user input flags and output edits.

Code system will also include any new modules/source files, possible changes to the build system of both codes, and changes to the LaTeX documentation harness.

Deliverable One for Subtask 11.2: A draft Software Design and Implementation Document (SDID) which describes the implementation of the technical specifications and algorithms outlined in the SRS, i.e., how the software will be structured and designed will be developed which outlines how the Hexagonal PPR will be implemented into the PARCS code system. The SDID will outline any anticipated code changes and possible code restructuring.

The SDID will be delivered to the COR 152 days after task commencement.

Deliverable Two for Subtask 11.2: Proposed verification tests will be included in a draft Qualification Test Plan (QTP), to include model inputs outlining the numerical verification tests that will be used to demonstrate the proper implementation of the Hexagonal PPR method. Higher fidelity models will be used for numerical verification (i.e., any lattice transport code, fine mesh finite difference diffusion code, or Monte Carlo code).

The Qualification Test Plan (QTP) also referred to as the test plan in NUREG-1737.

The QTP will be developed consistent with NUREG-1737 which provides for a document describing how the implemented capability will be tested, i.e. the test problems which will be used to demonstrate the new capability.

The contractor shall deliver the draft QTP with the verification test models to the COR 201 days after task commencement.

Deliverable Three for Subtask 11.2: A Beta Version of the PARCS/GenPMAXS Code Distribution(s) will be delivered to include the updated PARCS and GenPMAXS source codes (source distribution) which include the adapted PPR method.

The Beta PARCS/GenPMAXS build will be delivered to the COR 300 days after task commencement. The distribution will include updates to the test suite from Deliverable Two.

Deliverable Four for Subtask 11.2: An Updated Draft User Manual with additional flags that are needed to activate the Hexagonal PPR calculation will be delivered. The manual will also demonstrate how to view the additional edits from the method through existing or new PARCS output files.

The updated Draft User Manual will be delivered to the COR 321 days after task commencement.

Subtask 11.3: Finalization of Subtasks 11.1 and 11.2 Work Products The work products that have been cumulatively delivered with Subtasks 11.1 through 11.2 will be finalized and delivered for subtask 11.3.

NRC-HQ-60-15-C-0012 M0023 ATTACHMENT NO. 1 Deliverable for Subtask 11.3: The Finalized Deliverables will include the final revisions incorporating COR feedback on all documents and code deliverables associated with Subtasks 11.1 through 11.2.

The updated PARCS/GenPMAXS source distribution, test problems, theory/user manuals, the verification test problems, and SDID will be delivered to the COR 349 days after task commencement.
