Dear Dick:
Reference your transmittal dated 15 february 1980, and our verbal conversation on 9 May 1980, requesting our review of geotechnical investigations performed at Niagara Mohawk's Nine Mile Point Nuclear Station, Units 1 and 2.
We have reviewed Niagara Mohawk's responses to several of the questions posed to them in your memorandum dated 11 May 1979. As discussed with you previously, at the present time we will only be providing comments regarding Niagara Mohawk's response to Question 361.22. Since many of the questions regarding the investigation performed at Unit 2 are interrelated, I would prefer to withhold commenting on any specific response until all questions have been addressed by Niagara Mohawk.
Regarding the response to Question 361.22, it appears that the Utility has altered its position on the postulated cause for the crack in the north wall of the Unit 1 Reactor Building. At the meeting held on 24 April 1977, Niagara
.Mohawk indicated that the crack was 'suspected to be caused by rock squeeze of excavation walls. In their response to Question 361.22, Niagara Mohawk now states that the cause of the crack has not been determined. The 3-foot wide slot between the rock and substructure walls would seem to preclude wall con-vergence from horizontal rock squeeze as a likely cause for cracking.
However, as stated in the response, small movements of the foundation rock supporting the adjoining Screenwell Building's west wall, could produce suf-ficient load to cause cracking in the Reactor Building wall. Expansion of concrete comprising the west wall of the Screenwell Building was mentioned as another possible cause..
It is my opinion that the Utility should be required to evaluate the signifi-cance of the crack in the Unit 1 Reactor Building wall with respect to the safe operation of the plant.
