APPLICANT'S REPLY TO THE LEAGUE'S PROPOSED FINDINGS OF FACT AND CONCLUSIONS
> OF LAW REGARDING LIQUID PATHWAY As authorized by the Stipulation between all parties to this proceeding dated August 18, 1982, Commonwealth Edison Company (" Applicant") files this reply to the Rockford League of Women Voters' ("Intervenor") Proposed Findings of Fact and Conclusions of Law Regarding Liquid Pathway.
- 1. Intervenor's Site Characterization Intervenor's Proposed Findings 4 through 11 misstate the record with respect to the proper characterization of.
the Byron site geology and hydrogeology. Many of the " facts" proposed by the Intervenor are misleading-to various degrees.
In'Intervenor Proposed Findings _5 and 6, Intervenor
. states =that the bedrock underlying the Byron' site is extremely fractured near the surface ~and that the top of the ground-water table is in this' area of the bedrock.- These findings when read together with findings 7-11 suggest that contaminant

a travel times will be influenced by these characteristics.
However, the uncontradicted testimony establishes that at the Byron site the most highly fractured portion of the bedrock has been excavated, and, more importantly, that radioactive contamination under the postulated acc idents would enter the acquifer at approximately 62 to 70 feet from (Applicant the surface, well below the groundwater table.
Proposed Finding 328; Lahti, Applicant's Prepared Testimony at 4, ff. Tr. 6750.)
Intervenor Proposed Finding 7 states that the fracturing in the Galena-Platteville dolomites is regional l
in nature. The Applicant does not dispute this assertion.
however, that the l
Proposed Finding 7 goes on to state, regional fracturing raises a serious threat to the health j
and safety of the public, given the occurrence of a serious accident. Even given the regional nature of the fracturing, 1/ In fact, the l

assumed regional fracturing. (Holish, Applicant's Prepared Testimony at 7, 8, 16-18, ff. Tr. 6750; Codell, Staley, NRC Staff Prepared Testimony at 11, 12, ff. Tr. 6649.) In addition, the accidents postulated and analyzed by the Applicant (the BRH tank rupture and the core melt release) assumed regional fracturing. (Id. Lahti, Applicant's Pre-pared Testimony at 5, ff. Tr. 6750.) The consequences of

the BRH tank rupture were found not to endanger the health and safety of the public, and the environmental risks from a core melt release were found to be acceptably small. (Appli-cant Proposed Findings 341-344, 345-361.)
Intervenor Proposed Finding 9 is misleading. This Proposed Finding asserts, among other things, that at this time it is not possible to say that there is not a continuous joint running from the site to the Rock River. The testimony of both the Applicant and the NRC Staff is miscited in support.
The testimony of Applicant's witness, fairly read, is clearly to the contrary. At Tr. 6767, the page cited by Intervenor, Mr. Holish testified as follows:
O But you cannot say there is not a continuous joint running from this site to the river, can you?
A I cannot say that, on the basis of physically seeing the actual joint, but, however, my engineering judgment and the interpretation of the data that we have collected so far would lead me to believe that the joints are discontinuous, especially from the mapping that has been done.
The citation to the NRC Staff's testimony, Tr. 6711, con-
-tains no reference to continuous jointing. To the contrary, the NRC Staff elsewhere testified unambiguously that the results of Applicant's investigation show that continuous fractures or joints do not run from the site to the Rock River. (Staley, NRC Staff Prepared Testimony at 14, ff. tr.
6649; Staley, Tr. 6655.)
I -
Intervenor Proposed Findings 10 and 11, taken together, constitute a mischaracterization of the testimony of Dr. Bernard ~ Wood, who testified for the Intervenor.
2 Intervenors imply that Dr. Wood's method / for characterizing the bedrock underlying the Byron site assumes that the rock formation contains joints at irregular intervals. The record does not support this interpretation. Dr. Wood
- advocated the_use of tracer studies and fissure modeling because the fractures were in his opinion continuous, not because they were irregularly spaced. (Wood, Tr. 6893-6900, 6918-6919; Wood, Intervenors' Prepared Testimony at 5, ff.
Tr. 6879.)
In, conclusion, Intervenor Proposed Findings 4 through 11 are.not supported by the record.
- 2. Applicant's Site Characterization Intervenor Proposed Findings 13 through 17 consti-tute an attack on the Applicant's Byron site investigation.
These findings are not supported by the record.
In Finding 13 it is asserted that Applicant was
. unable to state.how many of the'154 core borings _ intersected joint: fractures. In-fact, Lawrence Holish testified that, on the basis of his examination of the drilling lobes and observation of theLcores, probably every single boring intersected a joint fracture. (Holish, Tr. 6751. )

'Although not. described, this' method apparently involves
- a tracer' and modeling study,: proposed- by Dr. Wood. in
-his prepared testimony'and the: subject ofLextensive cross-examination. .-(Wood, Intervenors' Prepared Testi-mony'at-8, ff. Tr. 6879; Wood, Tr.16919-6922.')
I l
Intervenor Proposed Finding 15 correctly states that Applicant has not performed a tracer study of contaminant migration from the Byron site to the Rock River. A tracer study is lengthy, difficult, and not well known by many engineers. (Holish, Tr. 6768, 6842, 6920.) In view of the adequacy of the Byron site investigation, such a study is simply not warranted. (Applicant Proposed Findings 317, 318.)
Intervenor Proposed Finding 17 incorrectly implies that, due to a possible factor of ten difference between effective porosity as calculated using the approach of D. T. Snow and that determined from in situ water pressure test and geophysical data, Applicant's final conclusion as to contaminant velocity is ten times too slow. At Tr. 6775, the page following that cited by Intervenor, counsel for Intervenor asked Applicant's witness that very question, i.e., could contaminant velocities as finally determined by Applicant be ten times too slow. The answer was "no."
Moreover, the Snow analysis was not used to evaluate design basis accident scenarios. It was one of two distinct methods employed to evaluate the hydrogeologic aspects of a postulated core melt release. Since the Snow analysis was designed for a kind of bedrock different than'that beneath the Byron l
site, the Snow analysis was used by Applicant only as a basis of comparison to determine the effects of aperture size and fracture size. (Holish, Tr. 6775; Holish, Applicant's Prepared Testimony at 25-26, ff. Tr. 6750.)
Intervenor's attempt in Findings 13 through 17 to
, cast doubt upon the credibility of the Byron site investi-gation performed by the Applicant is without merit.
In view of the foregoing discussion, Applicant respectfully requests that Intervenor's proposed findings and conclusions on this contention not be adopted by the Board.
Respectfully submitted,
