Several weeks ago Joshua Pearce at Clarion University in Pennsylvania released a study titled “ Thermodynamic limitations to nuclear energy deployment as a greenhouse gas mitigation technology .” In the study he stated... nuclear energy production would have to increase by 10.5% per year from 2010 to 2050 to both replace fossil-fuel-energy use and meet the future energy demands. This line, of course, made the headlines and has been picked up by several outlets and blogs . When looking into his calculations for this statement, he made one assumption error that overstated the above sentence by nearly a factor of three. Page 121, Section 4.1 of the study states: Richard Smalley pointed out that in 2004, the global economy consumed the equivalent of 220 million barrels of oil per day, which converted into electricity terms is the equivalent of 14.5 TeraWatts (TW), or 14,500,000 MegaWatts (MW) (2005). … With a nuclear plant having about 1000 MW (1 GW) of capacity, we would need 14,500...
Comments
- The nuclear fuel arrived on site on July 17 from GE.
- Expecting a December 2006 fuel load.
- Power generation is on schedule for May 2007. There was some hinting that this might happen earlier.
- The $1.8 billion restart project is on budget.
- Browns Ferry staffing was at 898 persons prior to restart. They are at 1015 now. They forecast a need for 1047 staff members to support 3-unit operation.
- About 2,300 contractor employees on site.
- Stone & Webster is the prime construction contractor.
- Bechtel is the prime design contractor.
- NRC will have an additional permanent on site inspector (2 -> 3), since it is their custom to have the same number of resident inspectors as operating units.
- There is a tremendous amount of testing and inspection, and internal and external approvals required as each of the many subsystems are turned over to the plant operators. (The subsystems of the Unit 1 are "owned" by the restart project, and the restart project sort of has to "prove" that the subsystems are appropriately designed and constructed and inspected/tested before the "operating plant" will accept them for operation.)
- The project involved 605,529 feet of cabling, of which 83% is installed.
- There are 41,038 cable terminations, of which 89% are complete.
- There is 15,137 feet of small bore piping, of which 96% are complete.
- I gathered that much of the unit's active equipment was either replaced or sent to the vendor for refurbishment.
