DOCKET 50-312 Attached is the report of a recent inspection by Mr. Dodds of construction activities at the Rancho Seco site. Two deficiencies were revealed during the inspection, for which a Construction Deficiency Notification was issued on June 18. The deficiencies related to the failure to follow Cadweld splicing procedures h
(the ends of rebar had not been marked in such a menner as to
. ins $)thepropercenteringofthebarendswithinthecadweld sleeve and the failure by the contractor (Chicago Bridge and Iron) to exercise proper care and control of low hydrogen welding electrodes. We anticipate prompt and effective action by the licensee on each of the deficiencies.
A caution against the use of Valcoline in the cleaning of heat f
exchangers, a subjec: brought to our attention by a recent memorandum i
from your office, was discussed with the project personnel by Mr. Dodds.
The licensee's evaluation of a weld joint in the penetration for the equipment hatch,the geometry of d ich is at variance with the code, appears adequate, considering the location of the joint.
The variance has been reviewed and approved by the State of California Code Inspector. The condition is highlighted here to bring it to the particular attention of the DEL for information. We are prepared to provide additional detail s't your request.
