Description

Seamless Integration

Nuclear Power Plants that deploy CANBERRA's powerful data management and analysis products such as OpenCDM and OpenEMS will have the instant integration of countroom information automatically. This information flow doesn't just involve counting results but also plant configuration information, eliminating hours of redundant and error prone data entry. This fast and simple data flow between applications saves time and money.

Unit/Sample Point Tables

Most power plant samples are collected on a regular route or schedule - that is, samples are repetitively collected from the same locations over time. The Apex NPP option includes a Unit/Sample point table that allows the user to pre-enter the sampling locations. The individual locations (sample points) are organized by unit (reactor). Also, each Unit/Sample Point combination can have one or more specific count procedures associated with it. When the Unit/Sample points are selected while defining a sample, only those associated procedures are shown to the operator - simplifying the user interface and reducing the possibility of error.

Nuclear Power Plant Analysis and Reporting

Production counting facilities such as Nuclear Power Plants have a number of specialized analysis and reporting requirements that help ensure compliance with regulations and technical specifications. Apex was designed with these requirements in mind. This countroom productivity suite takes the world class Genie™ analysis routines and extends them to provide a number of powerful features.

Reactor Coolant Gross Activity Analysis and Report

Calculation of gross reactor coolant activity is routinely needed to determine compliance with plant technical specifications. With APEX it's just another example of how standard analysis routines have been extended to provide special Nuclear Power Plant specific features easy-to-use.

The user can select to use one, two or three spectra representing the following combinations:

• Non-degassed sample
• Degassed liquid and stripped Gas samples
• Stripped gas, filter and filtrate samples

The sum of the activities are calculated and reported and compared to the last X/E-Bar result for the appropriate reactor unit.

Mean Energy Analysis (E-Bar)

The mean energy analysis feature takes sample data, allows interactive selection of activities, calculates total gamma and total sample activity, and determines E-Bar. With the flexibility of APEX, the user can use site-specific parameters to convert the mean energy calculated to an RCS gross activity limit.

Dose Equivalence Report

These reports are typically constructed for Dose Equivalent Iodine (DEI) and Dose Equivalent Xenon (DEX), but can be constructed for any nuclide. The report normalizes the activity of the nuclides of the specific element (e.g. iodine) so the dose received from all isotopes of that element are related to a specific isotope (e.g. ¹³¹I).

Decontamination Factor Report

This report determines how well a cleanup system is working. The report calculates the effectiveness of cleanup by radio-isotope by comparing the activities of the inlet sample(s) and outlet sample(s). The following calculation is done for each isotope:
DF=(inlet activity)/(outlet activity)
The software allows for one or two inlet samples and one or two outlet samples.

Air Sample Analysis

This feature calculates the Derived Air Concentration (DAC) for a number of samples. Results are reported by gaseous, radioiodine and particulate components. The user can also enter the ³H activity manually to include in the results. Report output includes nuclide activities, DAC values, DAC fractions and CEDE.
