t Request for Additional Information Application Dated February 21 and March 7,1997 Siemens Power Corporation
. Docket 70-1257 In the February 21, 1997 submittal, Siemens Power Corporation (SPC) requested to decrease the minimum average air velocity of laboratory hoods from 125 linear feet / minute (LFPM) to 80 LFPM.
In support of this request, SPC included excerpts from the American Conference of Governmental Industrial Hygienists' " Industrial Ventilation Manual." These excerpts do explain that hood velocities of 80 LFPM are sufficient under certain circumstances.
However, not included in SPC's submittal is the statement on page 4-11 of the same manual which states that for " low activity radioactive laboratory work, a laboratory fume hood may be acceptable.
For such hoods, a minimum face velocity of 100 fpm is recommended" [1].
Please describe the materials'used in the hoods, the type of work done, tracer testing, and/or other supporting information which demonstrates that the requested lower hood velocity will be sufficient to protect worker safety.
