## Chornobyl Safety Improvements: Technical Areas

**Training**
**Analytical simulator**
**Symptom-based emergency operating instructions**
**Management and operational control procedures**
**Quality assurance**
**Fire safety upgrades**
**Safety parameter display system**

## Training

***Objective:*****	****Improve operational safety through enhanced training ****	****for plant personnel**
**Activities:**
**Training on systematic approach to training**
**Analysis of training needs**
**Training course development**
**Provision of equipment**
**Training implementation**

## Analytical Simulator

***Objective:*****	****Provide an analytical simulator that will model Chornobyl-3, for training and for use in development/validation of symptom-based emergency operating instructions**
**Activities:**
**Computer provided, tested by S3 Technologies**
**Chornobyl-3 database developed by revising Kursk-4 database**
**Development of design specifications**
**Software model integration**
**Once simulator is in Ukraine, staff trained on simulator use**

## Symptom-Based Emergency Operating Instructions

***Objective:*****	****Improve operational safety by developing and implementing symptom-based emergency operating instructions**
**Activities:**
**Orientation training/training on development of protocols and flow charts**
**Development of procedure writers’ guide**
**Development of protocols and flow charts**
**Provision of computer equipment**
**Analysis**
**Verification and validation of instructions**
**Implementation**

## Management and Operational Controls Procedures

***Objective:*****	****Improve operational safety through development and implementation of improved management and operational control procedures**
**Activities**
**Orientation and management structure analysis**
**Procedures development**
**Equipment labeling and tagout activities**
**Procedure training**
**Implementation of improved program and procedures**

## Quality Assurance

***Objective:*****	****Improve operational safety through development of improved quality assurance procedures**
**Activities:**
**Orientation, training on QA overview and performance-based QA auditing training**
**ISO 9000 gap analysis of Chornobyl’s QA program**
**Development of select QA procedures**
**Implementation of procedures**

## Fire Safety Upgrades

***Objective:*****	****Reduce the risk of fire at Chornobyl by improved fire detection/suppression capabilities and improved fire separation of vital rooms/compartments**
**Activities:**
**Agreement with Bechtel National on material and equipment to be provided to plant:**
**Penetration sealing materials**
**Structural steel fire protective coating material -- purchased and installed by a Ukrainian company, Asken**
**Fire detection system -- Cerberus testing for Ukrainian certification, Energoproekt designing system**

## Fire Safety Upgrades, contd.

**Firefighter suits**
**Hose nozzles**
**Fire doors -- agreement among Chornobyl, Asken Company, and Pacific Northwest National Laboratory; Energoproekt producing design drawings**
**Floor coating materials -- testing in Russia and Ukraine**

## Safety Parameter Display System

***Objective:*****  Provide a safety parameter display system for Chornobyl-3 to help operators quickly assess the status of key plant parameters.  The system will enhance the implementation of symptom-based emergency operating instructions.**
**Activities**
