Feb 19, 2024 · Uprating generally involves physically modifying a plant to increase its generating capacity. 1 Since 1977, the Nuclear Regulatory Commission (NRC) has approved 144 power uprates with at least one in every state with operational reactors.
Feb 19, 2024 · 19 Feb 2024. View. Add to list. Nuclear power in the US has steadily contributed 19% of electricity since 1990, mainly through uprates. These uprates, approved by the NRC, have boosted capacity by 24,080 MWt or 8030 MWe, equivalent to over 7 new plant units. Most uprates range from 0-5%.
The three categories of power uprates are — measurement uncertainty recapture power uprates. stretch power uprates. extended power uprates. Measurement uncertainty recapture power uprates are less than 2 percent and are achieved by implementing enhanced techniques for calculating reactor power.
Nuclear power plant uprating is a timely and cost-effective way to provide incremental electric generation. Westinghouse has successfully implemented more than 150 plant upratings, providing more than 5000 MWe of additional power generation worldwide.

- Substation Uprating
All actions involving substation construction require heavy planning. This is especially true of a program of substation uprating or expansion. The trend is toward the assessment of existing substations and individual equipment to develop a predictive maintenance and substation life extension program. There are many figures that need to be carefull...
New vs. Uprating or Expansion Existing Substation
Cost is usually a primary factor when determining a course of action: construction of a new facility versus uprating and/or expanding an existing facility. Prepare construction cost estimates for the schemes under consideration. Generally speaking, substation designers should choose the plan with the most favorable cost/benefit ratio, provided that such action is consistent with the near- and long-range system plan. With facility expansion or new construction, designers should include in cost...
In uprating substation equipment, the cooperation of the equipment manufacturer is usually required. Although an agent or distributor for the equipment vendor may initially be contacted, obtain final determinations from the manufacturer’s headquarters engineering staff as to technical feasibility of the uprating, the cost of such work, and where th...
The process of increasing the licensed power level of a commercial nuclear power plant is called ‘power uprate’. In most cases, this is an economic way of producing more electricity in a nuclear power plant, while maintaining adequate safety, design and operational margins.
