The International OECD/NRC PWR Subchannel and Bundle Test (PSBT) benchmark (http://www.oecd-nea.org/science/wprs/egrsltb/PSBT/) encourages advancement in subchannel analysis of fluid flow in rod bundles. The aim of this benchmark is to assess and compare numerical models for the prediction of detailed subchannel void distributions and departure from nucleate boiling (DNB) to full-scale experimental data on a prototypical PWR rod bundle. The benchmark activity is an international project supported by US NRC and METI (Japan) and endorsed by the OECD/NEA.

Participants in the OECD-NEA PSBT benchmark are strongly encouraged to submit research and review papers summarizing their predictions and results. Potential topics include, but are not limited to:

• System code simulations: authors should clearly identify the models employed (e.g., two-fluid: 6 equations) as well as the constitutive relationships employed
• Subchannel code simulations: authors should identify the models employed (e.g., 4- or 5-equation drift-flux as well as lateral momentum models) as well as the constitutive relationships and other assumptions (e.g., mixing models and coefficients)
• Computational fluid dynamics (CFD): authors should identify the nodalization and models employed (e.g., wall boiling and interface models) as well as any additional closure models

Authors should also provide a description of the basic numerical methods, discretization details and grid, and closure relationships.

Before submission authors should carefully read over the journal's Author Guidelines, which are located at http://www.hindawi.com/journals/stni/guidelines/. Prospective authors should submit an electronic copy of their complete manuscript through the journal Manuscript Tracking System at http://mts.hindawi.com/ according to the following timetable:
