DUKE POWER COMPANY FACILITY:
CatawEa Nuclear Station, Units 1 and 2 SUBJ ECT:
SUMMARY
bF AUGUST 11 AND 12,1981 MEETINGS AND SITE VISIT TO ASSESS CONSTRUCTION COMPLETION SCHEDULE On August 11, 1981, the NRC staff met with Duke Power Company (Duke); and on August 12, 1981, they met with Duke and North Carolina Municipal Power Agency Number 1, Co-owner of Catawba Unit 2.
Both meetings were held at the Catawba site to discuss the scheduling of construction and to observe the construction activities completed or in progress. Attendeees of both meetings are listed in Enclosures 1 and 2.
NRC representatives included a member of the Caseload Forecast Panel (hereafter called the Panel).
is the meeting agenda, and Enclosure 4 is the handouts during the presentation.
The purpose of the meetings and tour was to provide for the staff's independent assessment of construction completion for Unit 1.
Duke's current estimate for construction completion and fuel loading for Unit 1 is November 1983 which is three months behind their earlier scheduled completion date of August 1983. On April 7,1981, Duke filed an update to their application for operating licenses which was tendered on March 26, 1979. Therefore, an ancillary purpose of the Panel's completion estimate was to provide a basis-for establishing a target date for review of the OL application.
Conclusions On the basis of the present construction status at Catawba, the NRC staff concluded that Du_k_ e's schedule for support / restraint design, fabrication and installation is overly optimistic to support Unit 1
~
hot functional _ testing scheduled for April 1983 and associated _ fuel Toaa cate of_ August 1983.
The staff also concluded that a more iT51Tstic fuel load date would be the first quarter of 1984, nominally February. Tn <iata. hanger design and construction are about 90 working days _behind_Dukels current target completion date. However, additional
~ resources are being added; and Duke's management is fully committed to this recovery effort. Although not presently impacting the completion schedule _ the staff not.edAat the schedule for terminating cables appeared to be tight (relative to the perfornance of other plaHsl ;,qnd
'thTt this area would further impact the schedule if instrument
~
.uall4bility is deiayeo.
ine staff inquired about uuke's priorities of McGuire 2 vis-a-vis Catawba 1 and was informed that McGuire 2 is being completed; and, therefore, Duke's experienced personnel are being transferred to Catawba which should expedite its completion.

, i The NRC staff noted that, based on Duke's construction completion date, the SER issue date will remain as scheduled and they indicated the need to visit the site again in April 1982 to verify the progres:: made by Duke during this period.

September 28, 1981 Mr. Harold R. Denton, Director Office of Nuclear Reactor Regulation U. S. Nuclear Regulatory Commission Washington, D. C. 20555 Attention:
Ms. E. G. Adensam, Chief Licensing Branch No. 4 Re:
Catawba Nuclear Station Docket Nos. 50-413 and 50-414
Dear Mr. Denton:
Your letter of June 9, 1981 to W. S. Lee requested quarterly updates of the proj ected construction completion date for Catawba Unit 1.
Our June 23, 1981 response confirmed our commitment to an A2 gust 1983 fuel load date but recog-nized that our work status at that time was three months behind schedule. We also outlined actions that were being taken to recover the lost time.
The following provides information for our first quarterly update.
In addition, information on erection rates of various commodities for the August accounting
. period are included as requested by W. H. Lovelace, NRC/MPA, during the NRC Caseload Forecast Panel visit in August 1981.
Future updates will provide erection rates for the period between updates.
Catawba Unit 1 is estimated to be 85% complete as of July 19, 1981. This unit is currently three months behind schedule. As we reported in our June 23, 1981 letter, a detailed schedule evaluation was made in June to better prioritize work and lessen the manpower impact by rearranging non-critical system turn-overs.
Some inprovement in the projected completion dr.e resulted from this evaluation. However, since June, the slippage of mechanical systems scheduled to be turned over to our Steam Production Department for functional testing has adversely affected the projected completion date. The net result is that we continue to project a fuel load date 3 months behind schedule (November 1983).
We plan to continue to monitor the schedule closely and make improvements where possible in an effort to meet our scheduled fuel load date of August 1983.
The following major milestones were achieved in the last quarter.
Start Finish Cold Pull 07/06/81 08/27/81 Hot Oil Flush 07/06/81 08/19/81 Stems Blow 06/24/81 07/11/81

Mr. Harold R. Denton, Director September 28, 1981 Page 2 Cleaning of the Chemical and Volume Control System (NV), our next major mile-stone, is expected to begin September 28, 1981.
We are currently applying special emphasis to a number of critical areas.
Among these are the preparation for cleaning the condensate systems, in the Turbine Building, completion of work to begin cleaning the major nuclear systems in the Reactor Building, and completion at the first phase of activities in the Fuel Building.
Manpower has been increased at Catawba to support our hanger erection plans.
Our total construction workforce increased from 3391 on June 23, 1981 to 3589 on August 31, 1981.
In addition to bringing crews up to full force, this increase includes the addition of 8 piping crews and 5 hanger crews. A second shift consisting of 5 hanger crews and 6 welder crews has been added for hanger erection as of September 14, 1981.
The following quantities of listed commodities were erected during the August Accounting Period (6 weeks).
Quantity Erected Quantity Remaining Commodities During Period to be Erected Structural Concrete (cy) 560 543 Piping (weighted value) 2,806 10,442 Cable Pulla (each) 590 3,593 Cable Terminations (each) 1,395 16,448 Instruments (equivalent loops) 154 2,717 Piping Support / Restraints (each) 2,399 21,960 Additional quarterly updates will be provided until issuance of the SER for Catawba.
Very truly yours, f}f}h)h.
