PURPOSE STATEMENT: THIS LESSON WILL PROVIDE THE STUDENT WITH AN UNDERSTANDING OF THE RESPONSE OF THE PLANT'S VITAL PROCESS INSTRUMENTATION DURING AND AFTER A MAJOR PLANT ACCIDENT. INCLUDING FAILURE TIMES AND FAILURE METHODS. THE STUDENT WILL ALSO LEARN ALTERNATIVE MEANS OF MEASURING LOST PARAMETERS. II.

State the probable failure modes of critical instrumentation when exposed to the adverse condition defined in the previous objective. 3. Describe what is meant by adverse containment conditions. i l: l 6. Describe at least one alternative means for measuring the following primary parameters: - RCS loop temperatures - PZR pressure PZ1 level - RCS flow rate Letdown flow rate 5. Describe the problems associated with the PZR pressure control system and PORV's at TMI-2 and relate how thage have been corrected at VEGP. \\ .s n

III. LESSON OUTLINE: NOTES I. INTRODUCTION A. TMI-2 accident 1. During first day - all instrumentation with a.rP s u c4 - * ~' -" ' exception of thermocouples worked satisfactorily. y,, u 2. Following accident several indicators f ailed due to: a. Being overranged (Temp instruments) b. Flooding of containment floor. 3. Failure prompted use of alternative means of measuring key parameters. B. Scope of Lesson o aIforNL 3 1. Problems associated with Pressurizer level control and PORV's at TMI. 2. Factors affecting vital instrumentation operability. 3. Alternative mesna of measuring key plant parameters II. PROBLEMS ASSOCIATED WITH PRESSURIZER LEVEL AND PORV'S AT TMI Misunderstandingofishthalpicprocesses. A. 1. Isenthalpic processes conserve energy (h) - R-U -6b-i T1-oo 2. As pressura drops via throttling process the steen M P ^"2 expands distributing the energy over a larger Tp-co, area. Therefore the temperature drops. 2. Isenthalpic processes not common knowledge prior to TMI-2. Now is part of training. . - < T.*

O B.

Misundesstand Valve Position Indication MI-MI L. W TF1 ao was demanded position, not actual pag 6 ties. 7 2. Therefore, when control switch was placed in shut position, it indicated shut when it was really still open. C. PORY Leaked Prior to Accident 1. Related to isenthalpic throttling process. 3 J

.c.e.x,s r-e -se u-ees 111. LESSON OUTLINE: NOTES 2. Tailpipe temperatures were prematurely high prior to the accident. Therefore, when the relief valve remained open it was not readily apparent. D. Industry misunderstanding of pressurizer level response during a steam space LOCA. 1. Pressurizer level thought to decrease as pressure decreases during all LOCA events. 2. During steam space LOCA, however, level rises as pressure decreases. a. Bubble moves to head area (hottest part of system) b. As head bubble expands, it displaces water into the pressurizer. III. ENVIRONMENTAL EFFECTS ON INSTRUMENTATION A. Radiation o 83Cm u L.* l 1. Adverse containment conditions f r radiation 5 are rad levels in excess of 10 R/hr. 2. No adverse effects on pressure, temperature, d/p instruments.

Pressure - no significant effect h c. d/p cellu (level) - level decreases (5 to '10% error at 300*F) C. Cont Ir 1. Adverse containment pressure greater than or equal to 4 peig 2. Adverse effects a. RTD's - no significant effect b. Pressure - changes reference for gauge pressures 4 i

Shorting out instruments 2. Adverse effects RTD's - fail low /high a. b. Pressure - fail low c. d/p cells - fail low IV. ALTERNATIVE MEANS OF MEASURING VITAL PARAMETERS g .q A. Pressurizer Level ?"-?? 0"? 2 7P-oo3 1. Measure d/p between liquid and vapor space sample taps (large errors) 2. Compare actual pressurizer hestup rate to pre-calculated heatup rate curves based on level vs. HUR with different curves for different combinations of pressurizer heaters. B. Pressuriser Pressure Si !? 0"2 2 Tf - o'o 1 1. Measure pressure at liquid or vapor space semple line 2. Use alternate wide range loop pressure instruments on hot less 1 and 4. C. RCS Flowrate pg 1. NC - DeltarT hstween hot and cold leg vide range temperasures. D. Letdown Flowrate -i'

Heat balance across letdown heat exchanger 2. Flow balance across VCT. E. Loop NR Temperatures 45-3B=QS3=4. Tf - co s 1. Use Wide Range temperatures. 2. Use core exit thermocouples 5

SUMMARY

A. Existence of reliable instrumentation vital to safe operation of plant. B. TMI showed danger of zeroing in on one indication, no matter how reliable it may be, or is thought to be. C. Alternative indications may be used to replace faulty instrumentation or act as backup indication for verification of actual plant or component conditions. s I e 4 e 9, cu b
