C.4 Additional Test Series C.4.1 Background Systems codes used to calculate the behavior of nuclear power plants under a wide spectrum of conditions contain large numbers of models and correlations. These models and correlations I

are developed from basic or separate effects experiments and validated and assessed against similar experiments. When incorporated into the systems code and used in a system calculation, many models come into play in a given calculation and interact with each other.

The performance of the overall code is tested through comparison with integral system test data.

There am three integral test facilities in the world suitable for performing integral systems tests in PWRs. One of these is the APEX facility located at Oregon State University. The other two are ROSA in Japan and BETHSY in France. The NRC has obtained data from a limited number of BETHSY tests and a larger number of ROSA tests. The NRC was able to specify a number of tests in ROSA under an agreement with JAERI related to AP600 testing. However, we need a facility under our control to conduct testing in areas not previously investigated.

Secondly, testing is needed to supplant data bases resulting from the LOFT and SEMISCALE testing program. Neither of these facilities was well scaled for small break LOCAs. LOFT was configured for large break LOCA blowdowns and had only a single active loop so multiloop phenomena could not be investigated. The loop was not well instrumented and some of the data that were recorded no longer exist. The data from the small breaks and transient tests are of only qualitative interest. SEMISCALE small break LOCA experiments were excessively distorted due to facility heat loss and in many instances the facility was not well documented.

The APEX facility is, therefore, of unique importance in improving the NRC's data bank in the area of integral systems tests. The facility can also function in a quasi separate effects mode to study certain important modeling issues such as phase separation at flow junctions and countercurrent flow.

C.4.2 Phenomena and Processes to be Examined Experimental programs are conceived and conducted in fulfillment of a mission, namely, to obtain information on some phenomena or process or on some integral response. The facility mission should be related to code requirements. For example, if flow regime modeling in the code is inaccurate or not well described, then an experimental program could be conducted to provide more accurate and extensive date with which irnproved models could be developed.

The need for data and the acquisition of data are, therefore, entwined. Modelers must identify and prioritize their information needs to allow for experimentalist to obtain data specific to these needs.

C.4.3 Facility Configuration Control and Characterization Code analysts require detailed facility documentation and characterization to construct accurate facility input models. Complete facility drawings must be available with sufficient quality assurance that the drawing set represents the actual facility and that records of facility modifications are kept. The facility must be characterized for pressure drop, heat loss, and characteristics of active components, primarily pumps and valves.

C.4.4 Correspondence Between Facility Design and Instrumentation and Code Model Structure Code models represent facilities his a set of nodes. Code output can provide considerable information on a nodal basis such as pressure, temperature, void fraction, flow rate, flow regime, etc, more so than is normally obtained from experiments. Experimental facilities have discreet measurements of pressure, and temperature, where temperature can be measured with finer resolution than obtained from code output. Void fraction can be measured locally or over and interval. Flow can be measured locally or in an integrated fashion in a catch tank.

The point is that the way measurement information is obtained from experiments and calculated results are obtained by codes will differ, but the correspondence can be significantly improved.

There should be interaction between modelers and experimentalist to obtain a correspondence in how the facility is nodalized and how it is designed and instrumented. For example, a vessel may be modeled by 10 axial nodes; there should be 10 intervals of differential pressure measurements corresponding to these 10 nodes (or vice-versa).

C.4.5 Measurement Accuracy and Uncertainty Some attributes can be measured with good or excellent accuracy such as temperature, pressure, and single phase flow. Other attributes are much more difficult to measure such as two phase flow rate, void distribution in a pipe, or local heat transfer. Expermentalists generally become very familiar with the capabilities and limitations of their instrumentation and instrumentation in general. The determination and repoding of data accuracy and uncertainty is an essential part of an experimental program. The capabilities = ar.d invitations in instrumentation must be recognized and understcod oy developers.

C.4.6 Objective The principal objective is to provide qualified data on the behavior of reactor systems suitable for assessment of thermal hydraulic systems codes. This integral system test data will replace obsolete and missing SEMISCALfi and LOFT data in the NRC data bank. The secondary objective is to determine the utility of CFD analyses for selected phenomena and issues important to reactor systems sa;ety analysis. The data will be utilized by NRC staff and contractors.

C.4.7 Areas of Investigation Approximately 4 tests are defined as follows to take place during the contract extension.

C.4.8 Stepped inventory Reductione These are natural circulation tests that cover the spectrum of primary system inventory condition until core uncovery and are, in effect quasi-steady natural circulation tests. These tests will consist of a test sefau at constant powers of 1% and 3% of full scaled power with stepped reductior.3 in inventory from normal inventory with stepped reductions to 90%, 80%,.

until the vessei mixture level is below the bottom of the hot leg.

i A low pressure series and a high pressure series should be run. Suggested pressures are 40 psi fr2 the low pressure series and 285 psi for the high pressure series, the latter being the I

normal operating pressure in the steam generators. This provide approximately an order of magnitude variation in the density ratio between the liquid and the vapor. The CMTs and accumulators are inactive in these tests. These will comprise a set of 4 tests of stepped reductions of inventory and are basic to code assessment.

C.4.9 Deliverables An analysis report should be prepared for the test series. A suitable thesis might fulfill part of this requirement. CFD studies may be performed on fluid-fluid mixing in the steam generator plena, cold legs, and downcomer. The scope and content of reporting follows. These reports are intended to subsume the preliminary test analysis report and quick look reports formerly prepared for each experiment.

C.4.9.1 Introduction The report must begin with a discussion the describes the philosophy and architecture of tha experimental and analysis effort. It must describe the overall objectives and scope of the effort. It must equally describe the limits of the effort and what is not being assessed and why.

C.4.9.2 Case Study The study must begin with a detailed discussion of the background, objectives, context, and scope. The phenomena / process being studied should be described including a physical description of the phenomena. The models to be assessed should be described, with reference M the models and correlation document of the RELAP or TRAC code. This should include a description of the two-fluid engineering model, the simplifying assumptions it con?ains and their justification, its range of applicability, and its scalability to the plant. Finall/, the available model for the phenomena should be described in conjunction with a liierature review of related, relevant experiments. The rationale for selection of particular experiments must be given.

C.4.9.3 Facility and Test Description A discussion should be provided of the experimental facility including its geometric layout, instrumentation, operation procedures, and other information. Reference must be made to the detailed facili'.y description and test results reports.

The experiments must be discussed including important thermal hydraulic information, initial and boundary conditions, and operational information pertinent to the calculation.

Ranges of conditions in the experiments, such as heat flux, mass flow rate, void fraction, pressure, temperature, geometry, and scaling must be discussed with respect to prototypic conditions. Measurement uncertainty must also be discussed.

I C.4.9.4 Results Results that lead to niajor conclusions should be clearly presented and discussed.

I Applicable key parameters must be discussed. The discussion should include:

The important physical phenomena that occurred during the experiments.

o-l-

o' Explain any unexpected or at first glance strange results particularly when experimental measurements are not available to give credence.

Data from each test shall be sent to the NRC data bank on Compact Disc in the data bank format.

j Journal articles and theses prepared using these data shall be sent to the NRC.
