EMERSONWestinghouse E 20 Training From Normal Operation to Se lectric Belgium 14 Catalog vere Accident Management

to the operators during an accident recovery. 

Course Approach

The teaching approach combined classic 

presentations where the physical aspects of the 

most important EOP recovery strategies are 

presented and explained with Case Studies, 

which put the attendees in situations for which 

they have to come up with answers to operator 

initiated questions or advises. The Plant 

Engineering Staff (PES) Case Studies in the 

following agenda are intended to provide 

information on the possible evaluations that a 

Technical Support Center (TSC), Shift Technical 

Adviser (STA) or Plant Engineering Staff (PES) 

would have to perform to support control room 

operators in case of accidents. This includes 

evaluations concerning: 

 RHR suction alignment 

 Need to transfer to hot leg recirculation 

 Establishing RCS letdown or not 

 Venting RV head or not 

 Post-SGTR cooldown method 

 Control of sump pH 

 SG overfill 

 Which SG to use for cooldown 

 Reinitiation of feed to a dry SG 

 RCP status 

 Long term plant status

ENGINEERING COURSES 

ENG 141: ASME Code Familiarization 

ENG 142: US-Nuclear Standards, Rules and Regulations 

ENG 143: Fracture Mechanics Applications 

 ASME CODE FAMILIARIZATION 

(ENG 141) 

Course Objectives 

The purpose of the course is to present the 

background and history of the ASME code for 

boiler and pressure vessel design and 

construction. Specific attention is also paid to 

the organization and use of the code. At the end 

of the course the attendees will be able to 

manipulate the ASME code for their own 

application. 

Practical workshops are foreseen to enhance 

code utilization. 

Course Outline 

DAY 1 

 What is the ASME code? 

 General introduction to the ASME B&PV 

Code 

 Comparison and relationship with other 

US and European Codes: ANSI, ASTM, 

AWS, ASNT, French RCCM, German 

KTA 

 Administration of the ASME Code and 

organization of the Code editions and 

addenda. 

 Why was the Code introduced and how is it
