The Nuclear Waste Policy ActThe Nuclear Waste Policy Act

• The Federal Government is responsible for nuclear waste disposal

• Those who benefit shall pay for disposal

• Disposal (was) to begin in 1998

• The Federal Government is responsible for nuclear waste disposal

• Those who benefit shall pay for disposal

• Disposal (was) to begin in 1998

"The costs of disposal should be the responsibility of the generators ... of waste and spent fuel"

-- Nuclear Waste Policy Act

• Program funding derives from two sources: Nuclear Waste Fund and Defense Nuclear Waste Disposal Appropriation

• The realities of the Federal budget process have limited the Program's access to the Nuclear Waste Fund

• Funding over the last 8 years has been over $1 billion less than requested

• If the site is licensed, outyear funding needs to design, construct, and operation

a repository will increase significantly

Nuclear Issues are Political Issues

“Any decision about the management of nuclear wastes must be made in the cauldron of intense public controversy.”

Historical and Projected Commercial Spent Nuclear Fuel Discharges

Sources: * Based on actual discharge data as reported on RW-859’s through 12/31/02, and projected discharges, in this case, based on 104 license renewals.

** Represents the aggregate industry pool capacity based on pool capacities provided in 2002 RW-859 (less FCR) and supplemented by utility storage plans. However, the industry is not one big pool and

storage situations at individual sites differ based on pool capacities versus discharges into specific pools.As of May 14, 2007Discharge Curves 051407.ppt

Actual Discharges*, all reactors (operating & shutdown)

Projected discharges, all reactors, 48 license renewals

Projected discharges*, all reactors, 104 license renewalsActual discharges, shutdown reactors only

Actual MTHM in dry storage, all reactors

There are 104 operating reactors and 14 shutdown reactors

~ 9,500 MTHM in dry storage (as of 5/14/07)

~ 3,800 MTHM from14 shutdown reactors

Current Inventory: ~ 55,700 MTHM from118 reactors (as of 12/06)

Spent Fuel Transportation• Excellent safety record

• Public anxiety nonetheless

• WIPP helped establish cooperative planning and coordination w/ States

• Yucca would start no sooner than 2017 and continue 24 yrs

• Yucca would include emergency response training and $ CSGMW

• Balance public info & security

25

Nuclear Waste Legislation• Not a good track record

• S. 2589/H.R. 5360– Land withdrawal for the site– Lift the 70,000 MT statutory cap– Reform the NWF appropriation process– Provide licensing, transportation and

other regulatory improvements

• Inhofe Multi-stage Licensing (S. 2551)

• Reid “take title” proposal (S. 784)

26

Nuclear Waste Fund Balance (in millions of dollars, based on FY 2009 Budget)

Balance at start of year $21,542

Receipts

Fee payments from utilities 764

Earnings on “investments” 1,173

Total receipts and collections 1,937

Appropriations from NWF for Yucca 247 (32 pct of fees paid)

Other related salaries and expenses 41

Balance at end of year $ 23,191

27

Why NWF Reform is Needed• Projected fee revenue $750 M

• FY 2008 appropriation 187 M*

• “Line loss” 563 M

The balance is credited to the NWF but in reality is either gone (spent) or inaccessible

* Defense adds $199M for total $387M in FY 2008

Reprocessing Basics• Banned in U.S. by Ford, Carter

• Done in UK, RU, FR, JA

• Present methods separate plutonium

• Economics not apparent, $ of U↑

• Decades away in US

• Likely siting and transport concerns

• Requires different waste storage

• Still need at least one repository

31

New Nuclear Plant Storage• NWPA still applies

– New Standard Contract needed– Fee for power sold still required

• COL will require a spent fuel management plan

• Likely to have more pool capacity

• Some utilities consider lack of disposal a dealbreaker; others don’t

• Reprocessing still a question
