New Analog Rod Position Indication System (NARPI):

NARPI — Upgrade Electronics for the Westinghouse Analog Rod Position Indication System

Is this your Rod Position Indication System?

• Inaccurate Indication
• Excessive Calibration Time
• Drifting Indication with Power Changes
• Nonlinear Detector Outputs

Why replace your whole system when you can upgrade to a modern, accurate system for a fraction of replacement cost?

Why tolerate inaccurate rod indication when you can correct problem channels by upgrading on an individual rod basis?

Why wait for an outage when you can upgrade selected channels while at power?

The New Analog Rod Position Indication System (NARPI):

• Provides automatic linearization of rod position curves.
• Provides automatic temperature compensation (for reactor power) on a system, group, or individual rod basis. On—board temperature compensation available.
• Requires minimal installation time. Virtually no wiring or physical changes required. Does not require removal of existing RPI cabinets. Minimizes impact on plant procedures.
• Greatly reduces calibration time. Initial calibration typically less than 13 hours. Subsequent calibration typically less than 3 hours.

NARPI modules have the same form, fit and function as the original models, but include component, operational, and maintenance enhancements. This includes full use of discrete electronics, individual module power supplies, and front panel access for calibration and maintenance.

The NARPI upgrades can be installed at your convenience as individual module replacements, a phased implementation, or complete system upgrade. 

Why not investigate this cost—effective solution to reduce the burden on plant staff and numbers of unplanned call—outs, and increase system reliability and accuracy?
