I - ! - { 3 ! y approximately 18 to 20 months Main Propulsior assistant. As Main 2| Propulsior Assistant my primary duties were all mechanical equipment 1 including reactor, fluid systems, chemistry and radiological controls, 3f 4j after the Thomas Jefferson, I served two years as Staff Instructor at the 01U prototype also in West Milton, New York. The first year of 5 that tour I was the leading engineer officer of the watch on shift in 6 charge of the watch section operating plant and training personnel. The last year of my duty there I was the Student Training Officer' 8 , responsible for production training, preparing students to go out to Si i the fleet and operate the ships. In 1976 I came to work for Metropolitian 101 l Edison Company in January of 1976 as a Supervisor of training at Three 11! ! Mile Island Nuclear Station. Primary responsibilities were operations 12| training, regulatory training as far as general employee training, ( emergency planning drills and general station staff trainings. In 14l January 1977 I was transferred to the Reading Corporate Office as Director of Training for generation for Metropolitian Edison Company. 16i t My duties in that capacity were not only overseeing the training 17| ! activities at the Three Mile Island Station but overseeing the fossil 18{ training requirements and corporate support staff technical training. 19| ; I served in that function until September of 1978 and at that time was 201 - transferred as maintenance supervisor at the Titus Station in Reading. 21 I The Titus Station is 240 M Watt cool fired plant. 22 23 RESNER: Ok, thankyou Mr. Tsaggaris, at this time I'd like to turn the 24 interview over to Mr. Essig. , 25| ! | | M 1 I m , .' , . * 4 i i ESSIG: Mr. Tsaggaris ah what we'd like to do this morning is to discuss *with you, sort of go through a chronology of your involvement with the event of 0400 on March 28 and just have you go through as best you recall at this time recognizing that it's been over a month ago now, the details may be a little fuzzy but we would appreciate the ! best you can recall the specific events that ycur were or duties that 6{ you were asked to do starting with when you received the initial call to come onsite. So if you quickly sort of run through the chronology i of your involvement, however we're interested primarily in the first 9| | three days following the event. That would be Wednesday, Thursday and 101 | Friday, 28, 29 and 30 of March. 11! ! 12. TSAGGARIS: On Thursday, March 29 I returned home from class I was 13 | attending that evening in Reading in the Graduate program and my wife 14! : informed me that I had received a call from Jim Seelinger requested 15i , that I report to the observation center Friday, March 30 at approximately 16i 11:00 to assume the duties of emergency control station coordinator up 17 i in the Unit 1 Control Room. I arrived at the 3bservation center at 18 approximately 10 a.m. on Friday March'30 and proceeded to the senior 19! ; person in charge who I believe at that time was Rick Barley in charge of the observation center watch. I received a clearance and took the 21 I bus onto the Island and reported to the Unit 1 Control Room. Bill 22 Potts was in charge of the ECS at the time and I spent the next hour, 23 hour and a half, failiarizing myself with communication setup, the 24 monitoring teams that were out and the monitoring scheme that was in 25\ , * I @b i i * . | ' | , - . i | [ 5 . y; progress. I tried to familiarize myself with the Unit 1 and Unit 2 - I 2 plant status and get a feel for the way the organization was being handled. 3t I received a turnover from Bill at approximately 12 to 12:30 in the afternoon and assumed the watch of emergency ccntrol station Coordinator. I was informed that I'd be standing 12 noon to 12 midnight wst.ch each day and' that I would be rotating with Bill an a, port and O;! f stalboard essentially rotation. 8 , ESSIG: Used sort of a Navy term... 91 10. ! TSAGGARIS: What that means is that we were on 12 hour shifts and I lit would take the 12 noon to 12 midnight and he would come in and relieve 12. and then I would come back the next day at 12 noon, Ok. 13 14I : ESSIG: At the time that ah you reported in the Mr. Potts do you know 15i how long he had been on duty as ECS coordinator? 16| ! 17' !

I ESSIG: At 12:30 you relieved Potts. 6| 7 TSAGGARIS: At that time as far as on and off-site monitoring, I believe we had one monitoring team on the west shore and one monitoring team on the east shore, one monitoring team onsite perhaps two, I can't exactly remember and we had monitoring teams, one monitoring ! team in a helicopter. There were several helicopters but one would go 121 up taking the team out and when he had to refuel, he'd land and then 13 | the team would transfer the other helicopter would go up.
