8 Fleet Modernization Upgrade

• 5 Spanish replicasimulators.

• Certified accordingto the ANSI-3.5

Introduction



All Spanish FSS had a specificmodernization plan.

• First Stage: Long-Term operation.- Modernization of Computers and

simulation environment- Modernization of Input/output System

• Second Stage: Improve OperatorTraining.

- Improve new codes/models to trainnew scenarios (shutdown sequences,severe accident...)

- Implementation of DCS

Introduction


10





Avoid obsolescence of SimulatorArchitecture:

• New computers, from Unix toWindows

• New Simulation environment

• Porting of the source code (newcompilation).


12





Avoid obsolesce of I/O System (hard tofind spare cards)

Tesis+ is the evolutionary design of theTesis I/O system.

It is a distributed system based on aTCP/IP network protocol (fast or GIGA-Ethernet) running under Windows OS(64 bits) with a client/server architecture.


14





• Migration to the Tecnatom model buildermodels (Team Suite: Team_Flow,Team_Logic, Team_Electric…)

• Upgrade thermal hydraulics codes tocope with new scenarios: midloop, openvessel…

• Add new codes to cope with SevereAccident Scenarios. MAAP



Codes/models Modernization: Shutdown Scenarios

• Best Estimated codes (TRAC_RT) upgradedto cope with incondensable gas, allowingcontinuous operation in outage scenarios.

• Highly demanded by training schools andthe regulatory body

• Scenarios to train based on PSA and plantoperational experiences

• More relevant midloop operations and open-vessel


17

DCS Modernization



DCS Modernization

• New DCS of Spanish NPPs such as newturbine digital control systems, new feed watercontrol systems, etc… have beenimplemented in FSS in the recent years.

• They are based on platforms such as OvationMARKVI, S7,etc…

• Implementation first in Simulators lead tonumerous benefits. Most important:

- Tune the DCS in Simulator- Operator Training in advance



DCS Implementation. Feed Water Level Control of Cofrentes NPP

• Replace the analog control system,panel components and humanmachine interfaces. Under MARKVIplatform of GE

• The DCS implementation pursued 4goals:

1. Control response analysis and tuning2. Plant operators training in advance3. Operating and Functional Procedures

review and validation4. HFE: Validation and Regulatory Body

requirements fulfillment

CONCLUSIONSLessons learned & operating experience



CONCLUSIONS

Benefits of the modernization process in the Spanish FSS:

• Extension of the simulators life

• Simulators stability and robustness

• Improved training in new scenarios

• The implementation in the simulator of the DCS prior than in plant, lead to these benefits:

- Detection of discrepancies and parameters adjustment- Training the operators in advance- Simulator behaviour closer to real plant- Physical Fidelity- Review of procedures- Validation of the HMI



Lessons learned & operating experience

1. Planification of Simulators Modernization� Avoid obsolesce and ensure long-term operation.

the sooner the better

2. Source code porting� Different results with different compilers

� Long time of testing: Whole simulator to be tested

3. Shutdown sequences� Long time scenarios: make the training sessions

dynamic and prioritized according to PSA

4. DCS implementation� DCS usually required of high level of detail
