DPC Letter, Shinshak to Zwolinski dated July 12, 1985
Dear Mr. Zwolinski:
l Forwarded for record purposes are twenty (20) copies of NES-prepared responses to questions posed by Battelle Pacific Northwest Laboratories on I
the LACBWR Post-Accident Recovery Cost Study. Battelle questions 4, 5 and 16 were resolved earlier as a result of discussions between Mr. Bill Manion of NES and Mr. R. Smith of Battelle.
Written responses had been sent to the LACBWR NRC project manager by
(
telecopy last Friday. Also, at Mr. R. I. Smith's request, a copy of the enclosed information was sent to him by Federal Express that same day.
We are hopeful that sufficient information has been provided to support the conclusions presented in the study.
Sincerely, 8511250247 851121 PDR ADOCK 050 9

Dear Dick:
Enclosed herewith is our recommended response to the questions we received from Battelle regarding the LACBWR accident recovery cost estimate.
We have appreciated your desire to have these questions responded to in the shortest time and least expense. We have' endeavored to do so and thus trust that the enclosed will satisfy Battelle's concerns.
Please contact me if you have any questions regarding the enclosed.

Page 1 of 4 RESPONSES TO BATTELLE PNL QUESTIONS RE: LACBWR POST-ACCIDENT RECOVERY COST ESTlMATE (REF: BATTELLE LETTER, R.I. SMITH TO J. STANG, NRC, DATED OCTOBER 11, 1985) 1.
Response to Question 1 The composition of the various staff organizations is shown in.
A total cost estimate for the pre-accident plant staff of $4,000,000 per year was used for the cost estimate (provided by DPC). These annual staff costs included an overhead rate of 34.9%.
The base study used an accident scenario that included 100% cladding failure without fuel melting. However, for purposes of providing a conservative estimate of recovery costs, the costs for reactor defueling were based upon NUREG/CR 2601 Scenario 3 which was based upon 50% fuel nelting. Thus, when the study was amended to include 50% fuel melting, there was no increase in the cost estimate for this activity. Therefore, the unit cost factors used in the LACBWR cost estimate are those used for the NUREG study.
The cost estimate for low-level radioactive waste disposal provides for labor to process waste (see Attachment 1), design and construction of a waste processing facility and equipment, vaste processing, packaging, shipment, and disposal at the Barnwell disposal site (see calculation notebook sheets, pages 64 through 71).
2.
Response to Question 2.
Provisions for these staff functions were provided per Attachment 1.
3.
Response to Question 3.
Consideration was given to these functions as shown in Attachment 1.
For example, in the additions to plant staff, additions were made to legal staff to provide support for a public information program, additional health physics personnel were provided to provide for the increased need for radiation monitoring during recovery, and additional staf f was provided for an increased need for regulatory agency liaison.
I Page 2 of 4 RESPONSES TO BATTELLE PNL QUESTIONS RE: LACEWR POST-ACCIDENT RECOVERY COST ESTIMATE (CONTINUED) 4.
Response to Question 9.
The personnel change room would be part of the structure erected for containment access.
5.
Response to Question 10.
The costs for processing and disposal of containment water are included in the total cost estimate. Labor for waste management is included in Attachment I and processing / disposal costs are shown in attached calcu-lation notebook pages 64 through 71.
6.
Response to Question 11.
The LACBWR cost estimate is based upon processing (e.g.
evaporation) of liquid wastes, solidification, packaging, and disposal of concen-trated liquids. The distillate from the evaporation process would be controlled such that concentrations of radioactivity remained within existing standards for liquid discharge to the Mississippi River. No cost estimate was made relative to the consequences of a "zero liquid release" criteria being imposed upon the recovery project.
7.
Response to Question 12.
The LACBWR cost estimate was based upon meeting the disposal criteria of 10 CRF 61.
The one cost factor that was not considered was the possibility of having to pay any extraordinary disposal charge that might be levied against " decommissioning wastes" or any regional compact surcharge that might also be levied in the future. Currently, the Barnwell site is charging a $0.29 per cu. ft. regional compact surcharge. The contingency included in the total cost estimate is intended to cover these types of issues.
8.
Response to Question 13.
The only costs included in the cost estimate for Task 10 shown in Table 4-1, are manpower costs. These estimated costs cover the preparation of work activity specifications, detailed operating / task procedures and the preparation of daily radiation work permits (RWP).
HELE Page 3 of 4 RESPONSES TO BATTELLE PNL QUESTIONS RE: LACBWR POST-ACCIDENT RECOVERY COST ESTIMATE (CONTINUED) 9.
Response to Question 14.
The General Undistributed Costs shown on page 82 cover both Phase I and Phase II activities.
10.
Response to Question 15.
The costs associated with Additional Contaminated Systems and Components Removal, shown in Table 4-3, relate to the contamination within the containment building that results from the accident scenario and are anticipated to be cleaned up as part of the
" normal" decommissioning scope of the work; as discussed in Section 6 of the study. Part of this estimated cost impact upon normal decommissioning relates to increased costs for segmentation and disposal of reactor components.
11.
Response to Question 17.
Section 2 of Addendum I emphasizes that the differential of the base study costs and the Addendum 1 costs reflect the estimated costs to be added to the base study in order to reflact the cost impact of adding the 50% fuel melting to the base study accident scenario.
The attempt was made to develop a reasonable yet "high" estimate in the base study.
In so doing, the base study cost estimate included costs related more to Scenario 3 of the NUREG estimates.
As a result of this approach,.certain key elements of the base study and Addendum I show no apparent difference.
For example, due to the use of certain estimates from Scenario 3 of the NUREG study, such as radiation burn-out of personnel, defueling methodology, time intervals of applicable activities, utility and engineering support contractor costs are the same in-both cost estimates and the recovery schedule is the same..
The final Addendum 1 cost estimate and schedule does recognize the complete impact of the 50% fuel melt accident scenario.
The apparent lack of cost and schedule increases is a result of the use of selected elements from Scenario 3 of the NUREG study in the base study.
ge 4 of 4 RESPONSES TO BATTELLE PNL QUESTIONS RE: LACBWR POST-ACCIDENT RECOVERY COST ESTIMATE (CONTINUED) 12.
Response to Question 18.
Additional costs for higher activity waste processing and disposal are reflected in Addendum 1 costs, shown in Table A-3.
13.
Response to Question 19.
The comparison in Table 7-4 of certain elements of the LACBWR cost estimate to that of the NUREG/CR-2601 was made in the context of the explanation provided. The explanation was primarily intended to convey the applica-bility, and therefore use, of certain cost elements from Scenario 3 of the NUREG study and how they were modified in relation to the difference in the plant designs considered in the two studies.
NES carees that the NUREG study cost estimates should have been adjusted to 1984 dollars for a more accurate relation to the LACBWR cost estimates, llowever, lack of this adjustment does not bear directly upon the bases for these cost estimates.
