ventilation system. The purpose was to establish the proper location of air sampling devices and duct sampling surfaces, Details and available results are in Tab E-k. 4.1.3 ~ Preparation of Prototype Air Samplers Drawings are in Tab E-5, 4.1. Preparation of Prototype Particle Collector Details and drawings are in Tab E-6. 4.1.5 Freparation of Prototype Beta-Decay Monitors See Tab E-7 for details. 4.1.6 Construction of Counting Chambers Available results are in Tab E-8, 4.1.7 4.2 Duct Section Design See Tab E= Pre-test Work on TRANSIT ABLE and TRANSIT BAKER 4.2.1 Experimental 4.2.1.1 Pitot traverses will be taken at selected points in the boiler air system aboard each vessel during dock trials, sea trials, and, if necessary, enroute to the site. The data obtained from these traverses will be used to: ential flow recorders. stations. 201.2 a. Calibrate static taps for use with differ- b. Determine air flow patterns at air sampler Pitot traverses will be made in the ventilation systems with the same objectives as described for the boiler air systens. The majority of ventilation measurements will take place aboard TRANSIT BAKER. For details, see Tab E-9, 4.2.1.3 One or more air samplers and collectors will be operated during dockside trials or mine the amount of background "dirt" picked up by the ST. .2.1.h one or more particle sea trials to detercollecting surfaces. LOUIS FRC One air sampler will be operated in the wash- down spray of TRANSIT ABLE during a sea trial to determine the resistance of the instrument to such abuse. 6 IE Is
