BRM ECIAAR POWER PLArf SDEJIATOR - CB30Ff VISIT
.n-On December 15 and 16, P. P. Collins and R. J. Darsey visited the Singer Link Company la Sunayyale, California to witness the operation of the BAM Nuclear Power Plant Simulator (EPPS). BIM personnel wem perfbming acceptance tests at this time prior to moving the EPPS to Iyachbarg, Virginia.
36W personnel present during the acceptance testing were Messrs. Beddens, Beach, Rosser and Marshall. Singer 1 Link personnel present included Mr. R. Perran, Project Manager, and Dr. D. Prederich, Qaief Programmer.
The EPPS is based on the BBEJD plant and is a duplication of the SIEJD cont rol room. The simulation appears complete. All valves, pumps and
,~
- fustrumentation associated with the primary," secondary, circulating and engineered safeguards are " live" and vary as plant conditions vary.
One excellent feature of the MPPS is the Bailey Meter integrated control system. Rather than program this system into the computer, the ICS is installed and aceives the conditions from the computer and, in turn, sends its output to the reactor and turbine controls. Eence, the response of the controls to a change in " plant" conditions should be identical to that on an actual Epi plant.
Real conditions are simulated. As examples:
(1) Valve stroke times are programmed into the computer so that systems containing slow moving valves flow increase of decrease gradually as the valve position changes.
(2) lights dim as electrical loads are changed, and (3) the main generator motors and rejects the load if improper paralleling techniques are used.
v However, progrsssaing is not complete. The most serious deficiencies noted by Mr. Bursey and me are:
(1) inability to duplicate low power conditions up to about 20%, (2) identical response of the four power range channels to a dropped rod located at the periphery of the com, and (3) excessive swelling of the pressurizer level during a normal heatup.
These and other deficiencies were discuseed with Mr. Doddens at the conclusion of our visit.
Two pieces of equipment, not installed as part of the MPPS, are the nuclear instrumentation and radiation monitoring cabinets. Mr. Doddens stated
$ hat these cabinets wem located on back panels and therefore were act lucluded. We pointed out to Mr. Deddens that an important part of operator training was to instill in the trainee the habit of verifying 80012000%

the proper operation of instruments prior to manipulating reester controls.
I Also, we mentioned the importance of following trends on instruments, rather than relyint, solely on alarr.s prior to taking eornctive action.
I plant to discuss these items with Mr. Doddens again and I believe we should require, at a minimum, (1) that one channel of each nuclear instrument be available so that the trainees can perfom pre-s't.artup checks and (2) sufficiert radiation monitoring instruments be available so that the trainees can r.onitor changes due to power increases, fuel failures, and excessive releases to the atmosphere.
At the conclusion of our visit we discussed the personnel that were to be the instructers_ at the NFPS center in Ignchburg, Mr. Doddens infor: sed us that three people, all with many years of military PWR experience, have been selected as instruct 4rs. We intend to request Mr. Deddens to furnish us with detailed resumes.
Based on our observations, verbelieve that the B&W EFPS will eventually be acceptable as part of a training program to qualify individuals for " cold" licensing examinations. The B&W personnel were extremely cooperative and are attempting to meet, or exceed, the requirements imposed in our letter dated December 18, 1969 We plan further visits to the MPPS when it is installed in Lynchburg to follow up on the deficiencien noted above.
