Abstract

Plant parameters and performance of an industrial plant such as a boiling water nuclear reactor plant can be assessed over a global network. Plant parameter and performance data are compiled from a plurality of operating plants, and this data is stored in a categorized historical database. Users are provided access to the historical database over the global network to perform self-assessments and generate comparison graphics showing percentile ranking, trending, etc. Data generated at a particular plant can be downloaded to a server site for more detailed engineering analyses using conventional methods. Reports and commentary on the analyses can be returned to the user via the global network.

Claims

1. A method of assessing plant parameters and performance over a global network, the method comprising:

(a) compiling plant parameter and performance data from a plurality of operating plants;

(b) storing the plant parameter and performance data in a categorized historical database; and

(c) enabling access to the historical database over a global network.

2. A method according to

claim 1

, wherein step (a) is practiced by receiving the plant parameter and performance data from the plurality of operating plants over the global network.

3. A method according to

claim 1

, further comprising comparing plant parameter and performance data among the plurality of operating plants based on the plant parameter and performance data stored in the historical database.

4. A method according to

claim 3

, wherein step (b) is practiced by storing the plant parameter and performance data in the categorized historical database according to plant type, and wherein the comparing step is practiced by comparing plant parameter and performance data by plant type.

5. A method according to

claim 1

, further comprising performing engineering assessments based on the plant parameter and performance data stored in the historical database.

6. A method according to

claim 1

, wherein step (c) is practiced by enabling categorized access to the historical database according to input parameters.

7. A method according to

claim 1

, wherein the plurality of operating plants are boiling water nuclear reactor plants, and wherein the plant parameter and performance data comprises reactor water chemistry characteristics and reactor performance data, step (c) being practiced by enabling access to the historical database to determine current reactor performance trends and to predict future reactor behavior.

8. A method according to

claim 7

, wherein step (c) is practiced by enabling categorized access to the historical database according to input parameters and by displaying data for a particular one of the plurality of operating plants.

9. A computer system for assessing plant parameters and performance over a global network, the computer system comprising:

at least one user computer running a computer program that effects compiling of plant parameter and performance data from a plurality of operating plants and storing of the plant parameter and performance data in a categorized historical database; and

a system server running a server program, the at least one user computer and the system server being interconnected by a computer network, the system server enabling access to the historical database over the computer network.

10. A computer program embodied on a computer readable medium for assessing plant parameters and performance over a global network, the computer program comprising:

means for compiling plant parameter and performance data from a plurality of operating plants;

means for storing the plant parameter and performance data in a categorized historical database; and

means for enabling access to the historical database over a global network.
