Mr. Johnson called me to inquire about equation 6 (on pg. 6) in NRC's Draf t f (jy b

(
Generic Position on Groundwater Travel Time (6/30/86). He pointed out that the g

be dimensionless, which would be incorrect since Kd

I commented that he appeared to be correct, but I told him that he should talk with p* 7 (.{

D Mr. Johnson also stated that his other major comments included: (1) that the use of i!
average scepage velocities is inappropriate for media in which fracture flow is dominant p
k 1-and (2) that the discussion of dispersivity in the position overemphasizes molecular k
y diffusion compared with hydrodynamic (mechanical) dispersion.
I thanked Mr, Johnson for his comments.
ACTION REQUIRED Request Dr. Codell telephone Mr. Johnson to discuss the comments.
