I have been involved in the turbomachinery industry for 45 years and thought I know a little about the evolution of steam turbines. Previously, I had been set straight in short order that the inventor of tilting pad thrust bearing was not an American from Philadelphia named Albert Kingsbury. Rather, it was an Australian working in England (not an Englishman) named Michell. I learned from the article entitled "Steam turbines power an industry" in the August issue of Power Engineering, that Sir C

I have read and reread Bob Smock`s March 1996 piece, "There`s gold in those old power plants," and for the life of me cannot find the rationale for the "movement."

I am writing with some concerns about Part 2 of the outage management report, "Focus: nuclear power plant outages," by Jerry Locsin, CSR Data Services, in the January issue of Power Engineering. There seem to be several problems with this article.

After reading the September 1995 issue of Power Engineering, I was disturbed with some of what appeared to be facts in an article entitled, "High-tech Cogen plant saves money at Wellesley College." First, BVA Cogen did not design the cogeneration station here at Wellesley College. BVA did the negotiation for the gas contract between Wellesley College and Boston Gas Co. The entire plant was developed by Wellesley College staff, and much of the design was done by Wellesley College staff also.

The "Opinion" editorials in the May 1995 and June 1995 issues of Power Engineering suggest a national power delivery system that is not in the best interests of the United States. While the goal of the deregulated electric utility industry is admirable, the immediate repeal of the Public Utility Regulatory Policy Act`s (PURPA) mandatory purchase clause which you support in the May editorial does not provide a path to that goal.

I agree with your "Opinion" editorial in the Power Engineering March 1995 issue (page 11). However, I believe that utility executives must start making decisions based on the long term (greater than five years) benefit to the company rather than the impact on the current year`s balance sheet. In the example you provided, few utilities are willing to spend $25 million for a 50-MW power uprate modification. The addition of 50 MW will result in nearly $10 million in revenue per year assuming an 80

A letter in Power Engineering, December 1994, concerning low-level nuclear waste gives the wrong information about the availability of waste disposal sites. At this time the sites are Richland, Wash., and Barnwell, S.C., and they only accept wastes from the states which are members of their compacts.

Operations and maintenance (O&M) is certainly one of the major expenses in the production, transmission and distribution from all sources of electric power. However, non-fuel O&M is typically just a fraction of total O&M and payroll an even smaller fraction of that. Dumbsizing staff has become quite popular, perhaps because of the agonizing personal and personnel noises it generates, impressing boards of directors and stockholders. These people haven?t a clue about power, but they know to the pe
