General Discussion & Basis For May 1979 schedule Revision 1.
Developments since.last NRC visit in March 1978 A.
F/C #5 develop:ent (Issued in June 1978) and laborers strike
~
5/1/78 to 6/15/78.
B.
F/C #5a developed in July 1978 (Target F/L Study) to factor in effects cf strike. Results:
No change in Fuel. Load Dates (utilized 3monthscontingency).
C.
F/C #5b development in March 1979 (Target F/L Study). Why: Obtain better definition of 1978 vork stoppage effects, evaluate latest known Project requirements (licensing, experience on electrical and small pipe installatien diesel generator studies) and schedule j
uncertainties, reevaluate achievabil'ity of Target F/L Dates.
Res2ts:
Contractor recommendation of interim chanEe in Unit 2 F/L from November 1980 to February 1981 with no change in Unit 1 F/L. Final adjustment may be necessary 'in Fuel Load Target Dates pending resolutien of licensing issues. and soils problem (August removal of preload).
D.
Revised CP Co Testing Concept (May 1979) hesults:
Chan6cd Unit 2 F/L Target to June 1981. No change in Unit 1 (excludes TMI-2 effects) and major open licensing issue.s end use this concept for F/C #6 preparation.
Basis - Revised logic of completing all construction, preoperational testing and HFT for both units. DBM vill cover in more detail.
E.
F/C #6 Developments (1) Preliminary finding in July indicated an increase in electrical quantities of 10 to 20% due to revised lengths of afe've: nge circuits, more circuits due to later information from sen: ors and refinement cf design is being looked at more closely for F/C #6 as to location of circuits and not using an average pulling rate; Most of increase in circuits is in yard for i
security. Thisf resulted in future unachievable inste.11ation rates and Target Fuel Load Dates which prpbably could not be met.
(2) CP Co Policy discussion to factor in F/C #6, the TMI-2 issues and Open Licensing Issues.
(3) Because of Items 1 and-2_ above, the revised Project Schedule and F/C #6 finalization vill be delayed until January 1980.

Dear Mr. Selby:
--neveWie Your letter of June 25,1M1 expresses your belief that the riidland docket is substantially complete, and that the SER should be rescheduled for issuance in January 1982 rather than July 1932. Your request is intenced to provide for a period of 18 months from SER issuance until a Commission decision, which you Delieve is necessary for plents with heavily contested hearings.
The NAC is presently reassessing its licensing schedule for.all calendar year 1983 plants wnich are expected to be heavily contested cases. As a result of this review we are evaluating the earliest practical date that a Midland SER can be published.
At this time, we are encouraged that the present July 1,19s2 cate could be improvec, provicing that year staff can support the level of activitiy requirec.
To citigate the impact of the present soils nearings on the time available for the assignec Licensing Prc]eci ': anger to cevote to review of the Midland FSAR, we nave assignec a second person to act in the Project i.an6ter's cencif in nis ausence and tc assist nic in cocrainating the revie.
The July Bevill Report issued in August retlects a revised date of hay 19e2 for issuance of tne hiclend Safety Evaluation Report (SER).
This schecule will allow 14 months fro. issuance of the SER to the Co=aission decision cate as co.mpared to 12 nonths previously. A case load forecast panel visit is seneduleo for toe Micland Plant on August 26-27, 1951.
Tne results of tnis visit will provide additioaal data to be considered in reassessing our license schedule for the Hidland Plant.
As you know, the NRC staff has initiated recent procedural changes in-tended to expeci ce current operating license reviews. Under these new procedures, you will be requested to make authorized members of your staf f available in Eethesaa for as many days as necessary to uncertake an intensive effort and face-to-face corcunications with the staff to resolve outstanding issues identified in early SER draf ts. The actual date of SER issuance for Hidland will depend pritaarily upon your abili,ty to support and provide substantive follow up of these intensive sessions.
The first few draf t SER sections have been forwarded to your staff and others are being forwarded as tney becone available. Most SER draft

a sections should be forwarded by the end of 1981. We anticipate the scheduling of review sessions with your staff once sufficient SEk draf ts have been forwarded, probably during the next one or two. months.

SUMMARY
OF SEPTEMBER 18-19, 1979 MEETIt'G AND SITE VISIT TO ASSESS CONSTRUCTION SCHEDULES On September 18-19, 1979, the NRC staff met with Consumers Power Company (the applicant) and Bechtel at the Midland site to discuss the scheduling of con-struction and to observe the construction activities in progress. The meeting agenda is attached as Enclosure 1.
Meeting attendees for the two days are listed in Enclosures 2 and 3.
NRC representatives included members of the Caseload Forecast Panel.
The purpose of the meeting and tour was to examine variations in estimated dates for completion of construction of the Midland plant. The applicant's current estimate is June 1981 for completion of Unit 2 and November 1981 for Unit 1.*
The generic-based estimate by the Panel prior to the visit was November 1981 for Unit 2** and November 1982 for Unit 1.
These estimates by the Panel are based upon a generic forecast acdel derived from previous history of similar plants and the applicant's reported percentage completion.***
The tour and discussions are an integral part of the Panel's prediction pro-cedure in which plant-specific factors are reviewed to determine if adjustments to the generically-derived estimates are appropriate.
Conclusion In the judgment of the Panel, another nine months will accrue before sufficient system turnovers occur so as to constitute start of the preoperational testing phase. The tests are estimated to require at least a 2-year duration, result-ing in a projected completion date of June 1982 for the first unit to be completed, Unit 2.

. JAN 161980 The staff noted the applicant's schedule assumes a sustained cable installation rate of about 1235 cables per month over a period of 17 months. However, the staff cited experiences of recent plants (San Onofre 2, Grand Gulf, Susquehanna, etc.) which were able to sustain an average rate no more than 800 cables per month over a similar period, particularly in view of latter phases as increased congestion became more severe and rates lower than the average occurred. The circuit rerouting analyses presently needed at Midland in view of a projected cable tray overfill problem which is causing temporary cutbacks in the number of electriciant employed at the site is typical of the types of events which affect cable installation schedules. Based upon this history and observations, the staff concludes the applicant's cable installation projection is overly optimistic.
The staff also noted that the overall Midland construction progress for the past 18 months had averaged 1.1% per month, whereas an average of about 1.8%
per month hereafter would be necessary to complete the remaining 39% of plant construction within the 22 months left until June 1981. An average of 1.8%
per month exceeds the progress demonstrated by past plants at this stage.
The-staff finds no basis to support such an increase at Midland and considers a lcwer rate over a longer duration to be more realistic.
The applicant's schedule.for Unit 1 is based upon a revised logic for pre-i operational testing in which testing of both units is completed prior to fuel loading of either unit. The staff's preliminary review of this logic during the meeting concluded that the applicant's differential schedule between unit completion dates appears reasonable. The staff's review of the Unit 1 schedule is limited in depth, and a more thorough review will be performed once the applicant's January 1980 forecast is completed. The staff's present estimate for Unit I completion is November 1982.
The applicant is currently developing a revised forecast (Forecast No. 6) to incorporate recent increases in electrical quantities and the influence of TMI-2 issues and open licensing issues. Forecast No. 6 will be finalized in January 1960. The estimate by the Forecast Panel does not presently include provisions for the effects of TMI and open licensing issues; however, the staff perceives that these effects will be quite significant to the ultimate completion date.

Discussions and Observations on September 13, 1979 1.
Plant Status as of September 1,1979 (G. Keeley)
CPC0 bases estimates of construction completion on manhours which correlate to work in place. The ratio uses actual manhours expended in the numerator, and the denominator is the sum of four factors:
- 1) the estimated total manhours to construct the plant; 2) an allowance to incorporate support effort and productivity of labor; 3) a factor to account for contingencies; and 4) a scope change factor. On the basis of total manhours for the project (both units and common) CPC0 estimates the plant is 62% complete.
On the basis of those manhours associated with installation of physical quantities (i.e., excluding certain support activities), Unit 2 is estimated by CPC0 to be 61% complete, and Unit 1 is estimated to be 54%
complete. Engineering is 82% complete.
Staffing levels for engineering and engineering support total 575 people, which includes 366 engineers. The total of 3,954 site personnel is com-
. prised of 2,238 canual personnel, 705 nonmanual personnel, 652 subcontrac-tors and 359 (of which about 200 are operating personnel) Consumers Power personnel. Some temporary reductions in wiremen at the site (discussed later) were in progress.
Expenditures for the plant are $1,150 million. Procurement is 95% complete based upon dollars expended.
Bulk material installations for the total plant, based upon the March 1979 forecast, were 88% complete for large pipe, 46% for small pipe, 95% for cable tray, 66% for conduit, 38% for wire and cable, and 26% ~ for connections.
Dow Chemical has received approval from the Michigan Air Pollution Control Commission for continued operation of the existing fossil units for process steam until December 1982. However, evaluation by the Environmental Pro-tection Agency is continuing.
Contracts for almost all site crafts are due for renegotiation in 1980.

Staff Presentation of Forecast Panel's Model and Results (W. Lovelace)
The staff described the model used by the Panel to forecast construction completion dates. The model consists of an average curve of construction versus time, based on the construction history of recent nuclear plants
~
which have received operating licenses. Using this curve and the reported percentage completion of construction for a specific plant, an estimate can be made of the time remaining for completion of construction. The generic-based estimate is then combined with observations by the Panel during a specific plant tour to arrive at that date which will be used by the NRC staff management when allocating and justifying resources.
The Panel's original estimate for Midland followd a March 21-22, 1978 site visit and concluded that although the projection for Unit 2 seemed a bit optimistic, the applicant's schedule of November 1980 for Unit 2 and November 1981 for Unit 1 appeared to be achievable. The Panel's annual update for 1979 resulted in a revised generic-based estimate for Midland which projected a one-year slip. This estimate by the Panel was based upon the reported percentage completion in the February 1979 Yellow Book which indicated Unit 2 at-56". complete and Unit 1 at 52".- - -

Aoplicant's Schedule Revisions (G. Keeley)
The visit by the Forecast Panel in March 1978 was based upon CPC0's Forecast No. 4.
In June 1978, CPC0 developed Forecast No. 5 which pro-jected a fuel load date of November 1980 for Unit 2 and November 1981 for Unit 1.
A laborers' strike from May 1,1978 to June 15, 1978 led to a reev&luation in July 1978 (Forecast Sa) and resulted in no changes in the fuel load dates, but utilized the three-month contingency in Forecast 5.
In March 1979, CPC0 again reevaluated the target fuel load dates (Forecast Sb) to incorporate better definition of the 1978 work stoppage effects, known licensing requirements, increases in projected electrical and small pipe installation, and backfill settlement effects. The Forecast 5b study resulted in a recommendation by Bechtel of a February 1981 fuel load for Unit 2 and'no change in Unit 1 fuel load. In May 1979, CPC0 changed the Unit 2 fuel load target to June 1981, without changing Unit 1, based upon a revised logic which calls for completing construction, preoperational testing and hot functional testing of both units prior to loading fuel in either unit.
Because of delays in conduit installation and the 1978 work stopoage, the start of cable pulling was delayed from January 1978 (as per
APPENDIX B..
Forecast #4) to September 1978. Additional electricians from Canada were added. However, the cable installation effort remains behind schedule.
i In July 1979, CPCO's preliminary findings indicated an increase of about 20% in electrical quantities. This results from revised lengths of average circuits, later information from vendors indicating more circuits, and refinement of the design. Much of the increase in circuits is in the yard for site security purposes. Nevertheless, a cable tray overfill problem is projected and rerouting analyses are currently being performed.
Pending completion of the rerouting analyses and cable tray engineering changes, a cutback in electricians was in progress during the Panel's visit ar;d was the subject of considerable local news media interest and brief picketing at the time. On September 14, 1979, 120 non-journeymen wiremen were laid off, reducing that force to 350 people. On September 19, 1979, an additional 15 electricians were terminated.
Quantities of piping and wiring for the various forecasts are indicated in the following table (see next page):

APPENDIX B..y 3.
Testing and Startup The revised logic and schedule for preoperational testing which was incor-porated into CPC0's May 1979 forecast is shown in the attached handout entitled " Midland Project Preoperational Test Sequence."
The previous and new testing philosophies are conpared in the handout, " Comparison of Philosophies." Under the revised logic, all construction and testing for either unit is completed prior to the fuel load of the first unit. The revised logic evolved from the realization that at least 75% of the total plant was required to be completed to support Unit 2 startup testing, that Unit I construction was ahead of schedule, that security problems would exist with Unit 1 under construction while Unit 2 was operating, that some tests involve both units and require checks for unit interaction, and other factors. The new logic has the advantage of providing efficiency and flexibility; however, it has the disadvantage that Unit I turnover dates are moved forward.
The test staff located onsite consists of 65 people assigned in 1979. This number will be increased to 75 in 1980. The status of the test procedures as of September 6,1979 is:
Total scheduled 104 (33.'4%)
Total drafted 113 (36.3%)
Total in internal review 68 (21.8%)
Total approved 11 (3.5%)
Preoperational testing of various systems are initiated once Bechtel canpletes installation and initial checkouts and turns the system over to C PC0.
Systems turned over to date include the discharge pond and plant canputers. CPC0 finds that system turnovers are about three weeks behind schedule based upon its May 1979 schedule.
4.
Schedular Impact of Backfill Settlement Effects (T. Cooke)
CPC0's May 1979 Forecast concludes that the remedial actions to correct the soils deficiencies at the site are not critical path items, and will be concluded with about 10 weeks of float. Remedial actions for the Auxiliary Building and Service Water Intake Structure have no impact upon other scheduled activities for these structures. Temporary cross-over piping will be installed between Borated Water Storage Tanks since the contents of one tank will be used during startup testing. No corraction of the diesel fuel oil tanks is planned sir.ce these tanks were preloaded with water and no settlement was observed. The 20-foot' sand surcharge was removed from the Diesel Generator Building on August 24 and a slight rebound was measured. The rebounds (differential readings fcr 8/10/79 and e
