Semiscale Mod-3 is part of the overall Semiscale blowdown and emergency core cooling (ECC) project conducted by EG and G Idaho, Inc., to investigate the thermal and hydraulic phenomena accompanying a hypothesized loss-of-coolant accident (LOCA) in a pressurized water reactor (PWR) system. The primary objective of the Semiscale Program is to obtain representative integral and separate effects thermal-hydraulic response data to provide an experimental basis for analytical model development and verification. An additional objective is to provide other Nuclear Regulatory Commission (NRC) sponsored programs, such as the Loss-of-Fluid Test (LOFT) Program, with support in test planning, evaluation, and experiment design. The purpose of the document is to establish the experiment specifications for the tests in Test Series 8 of the Semiscale Mod-3 Program. Test Series 8 is designated as the Upper Head Injection (UHI) Emergency Core Cooling System (ECCS) evaluation test series. The information contained in the document is suitable for the preparation of detailed experiment operation procedures for the tests in Test Series 8. Included are: (1) individual test objectives and basic description, (2) general system configuration, (3) specific system requirements for various tests, (4) general instrumentation specification and operation, and (5) special instrumentation requirements where required.
