One last thing...
US coal-fired plants are OLD !
For 14 coal-fired units in this territory (about 5000 mw), a rough weighted-average age is 47 years !
Mechanical condition alone may make these candidates for retirement– what would a carbon tax do ?

• CHANGES IN THE WIND...– 1992: Disaggregation of the industry– Environmental refocussing:
• 1969: SO2
• 1980’s: Ozone, oxidants
• 1990: Mercury
• 1995– Greenhouse gases, CO2

ON THE THRESHOLD
• Nuclear as baseload
![Page 14: Nuclear Renaissance- Real, or Imaginary ?. Framework: I. A Bit of History II. Change Happens III. On the Threshold– Maybe IV. Where Things Stand Now.](https://reader035.fdocuments.in/reader035/viewer/2022081501/56649e9f5503460f94ba254c/html5/thumbnails/14.jpg)
DAILY INTEGRATED ELECTRIC LOAD
![Page 15: Nuclear Renaissance- Real, or Imaginary ?. Framework: I. A Bit of History II. Change Happens III. On the Threshold– Maybe IV. Where Things Stand Now.](https://reader035.fdocuments.in/reader035/viewer/2022081501/56649e9f5503460f94ba254c/html5/thumbnails/15.jpg)
ON THE THRESHOLD
•Nuclear as baseload
•Unable to follow load
•Economics:
•High first cost
•Low operating cost

NEW PLANT DESIGNS
1) Emphasis on passive safety(Engineered safeguards are not first-
line defense)2) Precertified designs (Except for site-related differences)

BUT...
![Page 21: Nuclear Renaissance- Real, or Imaginary ?. Framework: I. A Bit of History II. Change Happens III. On the Threshold– Maybe IV. Where Things Stand Now.](https://reader035.fdocuments.in/reader035/viewer/2022081501/56649e9f5503460f94ba254c/html5/thumbnails/21.jpg)
BUT...
Financing is MUCH more difficult!
--Disaggregation of industry makes
utility financing like manufacturing
![Page 22: Nuclear Renaissance- Real, or Imaginary ?. Framework: I. A Bit of History II. Change Happens III. On the Threshold– Maybe IV. Where Things Stand Now.](https://reader035.fdocuments.in/reader035/viewer/2022081501/56649e9f5503460f94ba254c/html5/thumbnails/22.jpg)
POSSIBLE SOLUTIONS1) Consortia
2) Government loan guarantees
![Page 23: Nuclear Renaissance- Real, or Imaginary ?. Framework: I. A Bit of History II. Change Happens III. On the Threshold– Maybe IV. Where Things Stand Now.](https://reader035.fdocuments.in/reader035/viewer/2022081501/56649e9f5503460f94ba254c/html5/thumbnails/23.jpg)
WHERE WE STAND NOW:
-More than 30 announced projects(some construction started)
-17 requests for COL (26 units)(but nothing issues until 2011)
-Mostly consortia-Mostly existing sites
(reduced likelihood of interventions)-Gov’t loan guarantees piddly
