Dear Mr. Tourtellotte:
Please find enclosed the backfitting and regulatory impact cost data from the Omaha Public Power District's Vort Calhoun Nuclear Plant. Data is presented for Nuclear Regulatory Commission requirements (TMI and other Commission imposed backfits). We have also included data for the District's initiated modifications.
A review of the data presented in the attachments to your February 8, 1983 letter reveals that only hardware and analyses costs are included. The District believes that, the "backfit" and regulatory costs involving other Ccmmission imposed requirements chould also be considered. These costs would include additions to staff, testing of equipment (e.g., hydrostatic testing and leak testing), increased training requirements, plant drills such as annual emergency plan exercises, and procedural requirements.
An example of these "non-hardware" costs is the presently proposed rule-making regarding the requirement for adding one additional Senior Reactor Operator to each operating shift. The Commission estimate that it will cost each utility $600,000 per year is probably reasonably accurate.
Projecting this annual cost for the lifetime of a nuclear plant clearly demonstrates that all major "backfit" costs certainly involve issues other than hardware.

The Omaha Public Power District supports the Regulatory Reform Task Force activities, and members of our nuclear staff are available to support your efforts in this area.

FORT CALHOUN STATION l
i i
i The. Fort Calhoun Station consists of one pressurized water reactor, with an electrical rate of 501 MWe (gross).
l The nuclear steam supply system, nuclear fuel, and turbine generator were purchased in October,1966.
The provisional constr'.tction permit was received in June, 1968 and commercial operation began in September, 1973.
t I
In addition to the $178 million construction cost for the plant, S50 million has been spent on backfitting.
Of this $50 million,
$41 million was for NRC imposed costs which included TMI related l
The remaining $9 million in backfitting costs were for 4
those initiated by the District.
The plant value, as of
{
lj December 31, 1982, was $211 million.
The difference between the 1
initial cost of $178 million and the December 31, 1982 value of S211 million is $32 million, which is that portion of the $50 l
million that has been capitalized.
The remaining $18 million will l
be accounted for by work in progress, which will cost approxi-mately $11 million.
Operating accounts have been charged with $7 i
million.
The attached summary sheet ar.d Appendices A throuch C l
provide additional details for these costs.
It is presently estimated that near term future backfit' costs will
(
be $22 million.
Additional information on these future costs is provided in Appendix 0.
I Although not identified as an NRC imposed backfit, the Nuclear 1
Waste Policy Act of 1982 will result in a very substantial cost to. !
the District.
For the Fort Calhoun Station, it is estimated that presently accumulated liability relating to this act is $33 million and will be over $400 million by the year 2000.
