l ABSTRACT Y . The 197f Annual Report of Nuclear Operations provides a summary of reactor operating experience, facility maintenance and design changes, surveillance tests, summary of radioactive effluents released to the environment, surveys conducted in and outside the reactor facility, and a summary of radiation exposures received by facility personnel and visitors for the time period January 1, 1979 to December 31, 1979 This report is prepared in accordance with the Technical Specifications of Appendix A, The Catholic University of America Facility Operating License R-31, Docket 50-77, Amendment No.7 issued by the U.S. Nuclear Regulatory Commission on March 12, 1979 i O A .. m.

l A. Reactor Operating Experience
- l. The reactor was brought back into. service at noon on May 9,1979, af ter being in the shutdown condition since February 22, 1975 Prior to this event, Dr. David Ebert was issued a Senior Reactor Operator License (SOP-3426) by the Nuclear Regulatory Commission (NRC) on January 17, 1979 The Facili ty Operating License No.R-31 was renewed by the NRC on March 14, 1979 A Reactor Restart Report was prepared and submitted to the NRC on August 9,1979 This report is reproduced in Appendix A. -
No changes to the facility design or performance characteristics which relate to reactor safety were undertaken'during the reporting period. Routine startup, operating procedures and emergency procedures have been modified considerably from what had existed previously. These procedures were approved by the Reactor Safety Committee prior to restart. Copies of these procedures are reproduced in Appendix B. Routine surveillance tests and inspections have been carried out at intervals specified in Appendix C. Resul ts of these surveillance tests and inspections are contained in the Facility Maintenance Log and the Reactor Operations Leg. The reactor has been used almost exclusively as part of a Nuclear Engineering Laboratory course which was offered during the summer and fall semesters of the reporting period. Some of the experiments conducted with the reactor con-I sisted of /M approach to critical, power calibration, control rod calibration, and flux distribution. There were a total of 33 meaningful startups carried out during the reporting period, for a total of 14.6 hours at critical conditions. A monthly tabulation of reactor operation is sho~wn in Table 1. Also' contained.in Table 1 l
~
e . is a listing of scrams, both scheduled and unscheduled. Details are covered in the next section. A routine inspection of reactor operations was made on October 29 & 30, 1979 by C.O. Gallina and K.E. Plu.r.l of the NRC Region I office (Inspection #50-77/79-03). Two minor items of noncompliance regarding posting of notices were identified. These noncompliance items were corrected on November 5, 1979 A concurrent investigation was undertaken by the same two investigators which covered several allegations relating to the operation of the reactor and related radiatio . safety and securi ty programs (Investigation #50-77/79-02). The allegations were part of a petition flied with the NRC on October 3,1979 The results of the investigation indicated that..."of the seven allegations investigated, five were found to be unsubstantiated. The remaining two allegations, while substantiated, involved minimal impact on reactor operations, safety and/or security, and did not violate any licensee or NRC requirements. No items of noncompliance or deviations are cited in this report."
- 8. Unscheduled Reactor Shutdowns and Scrams i l
Manual Scrams: There were a total of 18 manual scrams, one of these was 1. unscheduled. This unscheduled scram occurred when the operator inadvertently brushed gainst the scram button located on the horizontal expanse of the control panel .
- 2. Period Scrams: There were a total of 25 period scrams; all of them were unscheduled. Seven of the 25 were due to operator error, the remaining 18 due to Ins trument mal function, The period meter is a signal differentiating instrument which is connected to the Channel 2 log ammeter. Small fluctuations in the Channel 2 ammeter cause much larger fluctuations in the period meter
- which subsequently caused the 18 period scrams. The problem was traced to a small amount of water leaking into Channel 2 neutron detector housing causing fluctuations in the detector current. When the detector and housing were dried, the large fluctuations disappeared.
3 Channel 1 High Level Trip: There were three high trips on Channel 1. These were all due to operator error by either not changing scales soon enough or changl'ng scales in the wrong di rection.
- 4. Channel 2 Low Level Trip: There were two low level trips on Channel 2.
Both were due to the reasons discussed under period scrams, for large negative fl uc tua t ions. 5 Channel 3 Low Level Trip: There were 11 low level trips on Channel 3 Five were due to operator error by either not changing scales soon enough or changing scales in the wrong direction. The remaining 6 low level trips were due to large fluctuations in the ammeter current. The. source of these fluctua-tions is not clear. It is apparently not due to moisture in the detector housing, however~. The fluctuations come and go unexpectedly, subsequently I making it difficult to locate the cause.
- 6. Channel 3 High L'e vel Trip: There were 4 high level trips on Channel 3 l
Two were due to operator error due to the same reasons given in section 5 The remaining two were due to large current fluctuations as described in section 5 also. C. Preventive and Corrective Maintenance l No major safety. related corrective or preventive maintenance were performed l I since the last Annual Report which would have an ef fect on the safe operation j of the reactor.
O D. Changes Which Affect the Facilities Description None E. Changes to Procedures as Described'Ib the Technical Specifications
- 1. Item 16.6.1.2 - The office of the Executive Vice President and Provost has been separated into two offices, that of the Executive Vice President and separately that of the Provost.
- 2. There has been extensive changes to the following procedures: Routine startup, operation, shutdown and emergency. Copies of these procedures are reproduced in Appendix B.
F. New or Untried Experiments None G. Radioactive Effluents -
- 1. Liquid: None .
- 2. Airborne: None 3 Solid: None H. Environmental Radiological Surveys Performed Outside the Facility No radiation surveys were performed outside the Facility during operation.
i However, the gamma field at the reactor console during 25 MW operation was 0.3 mr/hr. The gamma field at the nearest outside wall is reduced by a factor of 10 compared to the reactor console. There fo re, it can be concluded that the maximum gamma field at an outside wall would be about 0.03 mr/hr. No neutron radiation would be detected outside the facility, Random wipes of surfaces both inside and-outside the Reactor Room have not detected any loose surface activity above background. I.

1-Backgrounh and Introduction t . The reactor was placed in the shutdown condition on February 22, 1975 and not operated again until May 9,1979 Repair work was initiated on June 15, 1978 by Dr. David Ebert and Mr. Vindsor Dempsey. Dr. Ebert I received a Senior. Reactor Operators License ( on January 17.1979 and the Reactor Operating License was extende iother 20 years on March 12, 1979(2) . Re air and necessary paperwork to ve. , and document conformance to the new Technical Specifications was completed on May 8,1979 The reactor was restarted on May 9,1979 following the approved Reactor Restart Procedures (approved by the Reactor Safety Committee).(3) O in the subsequent months following restart,1) a power calibration, 2) 1 control rod calibrations, 3) measurement of k,x and, 4) verification of ' shut down margins were performed and observed to be both consistent with f. previously determined values and to conform:with the Technical Specifi- ,
~ '
cations.(2) The reactor is now being operated on a routine basis. 1

- 1. . Verify that all the maintenance and tests are in conformance wi th the Tech Specs. and have been car'ried out and documented. .
- 2. Perform I tems 1-9a of the Prestartup Checkout Procedure, but leave the Cd foil inserted in the glory hole position.
l 3 Undertake a 1/H plot as SR #1 is inserted, estimating the critical position l
~
of each step. 1
- 4. Assuming that the reactor is still subcritical with the SR #1 Inserted, t estimate the subcritical neutron multiplication constant (k) under the l
condi tions that all rods are out of the core (ARO) and the Cd foil inserted. h This k will be - K,5 I- SM where R; is the ratio of the neutron detector ;
. readings of SR #1 out tol-Rt inserted (R y<:1). R; can b'e computed for each detector I and applied, and then averaged and appl.ied. A gg is the assumed reactivity worth of SR #1 ( N 0.0125). f.

If this is not the case, Step 7 should not be undertaken until the descrepancy is resolved. 7 From the above information, assuming that the Cd foil has been removed, estimate and verify a. that the shutdown margin (wi thout Cd foil) is ?f 2 Io l2. j with the most reactive rod inserted; b. that the estimated k is /,.

- 8. Provided that all the above conditions have been , satisfied or discrepancies resolved,1/M measurements should be undertaken as the SR #1 and 2 are inserted.
Af ter SR #1 has been inserted it should be scrammed according to Prestartup Check 9b. Likewise, af ter SR #1 and 2 have been inserted they should be scrammed according to Pres tartup check 9c. .
- 9. Criticality should be achieved at the lowest practical poser level since a power calibration has not been undertaken for 5 years (approximctely id4).

Chann61 #1 = 584K cpm /100 cu - Channel #2 = 114% / 100 mW
. Channel #3 = 4.13 x 10'I Amps /100 mW These factors are consistent with those obtained in the past l years of operation.
. b) Control Rod Calibration Results: . -
The integral rod worth for the fine control rod is given in Figure 2. The total worth of the fine control rod was deternined to be 0.142% ok/k and the dif ferential worth was measured to be 76 pp/cm in the linear region of the range. The differential rod worth for the coarse control rod was determined to be 607 pp/cm.
%e total worth of the coarse control rod was inferred to be i i
1.14% ak/k. These values are consistent with those obtair.ed in 1 the past years of oner.' tion.

l c) k Calculation:
- The excess reactivity at 20*C which would result if all the
~
control and safety rods were inserted was determined to be 0.435% 0# k. This valta is less than the Tech. Spec limit of 0.65% ak/k and is consistent with the value obtained I'n
~
the past years of operation. i s d) 1. The shutdown margin with the most reactive rod inserted I at 20 5*C was determined to be -2.0% ak/k. The choice of 20.5'c was cho;en becatse . this was the lowes t temperature at which the reactor was operated since May 9,1979 This particular Limiting Condition for Operation r (LCO) therefore O defines the minimum tengerature for operation when the 91oh
'1 hole is empty and the normal material in the Access Ports.
II. The shut down margin with theleast reactive coarse or safety rod removed and the oth'er rods inserted was determined
/
to be -0 71% ak/k at 20.5'C. This value is within the limits established by the Tech. Specs. t 1

B. Precautions
- 1. To avoid an inadvertent scram, the ranges for chan.iel 1 and channel 3 should be changed when readings have reached slightly greater than mid-scale.
- 2. The reactivity addition rate shall be limited such that the neutron level is not permitted to increase at a rate which would result in a stable period of less than 10 seconds.
I fe ,
. 3 If abnormal neutron flux levels or instrument operation is observed at any time during the startup, a manual scram shall be initiated and the Reactor Supervisor immediately notified.
The startup shall not proceed until the abonormality is resolved and corrected. h C. Procedure 4, 1. Check the four DOWN limit lights and the four ENGAGED lights ON. Depress the Magnets On pushbutton to energize the control and safety rod magnets. Observe the MAGNETS ON light energized. NOTE The ENGAGED light for the FINE Control Rod has no meaning since the rod is not carried by a magnet.
- 2. Record the rod position and flux monitoring instrument readings.
i 3 Insert the Safety Rods, first No. I and then No. 2, to their UP l I limits. During rod insertion, carefully. monitor the flux level ! Instruments to ascertain that Instrument operation and neutron flux level behavior is normal . Observe the rod position windows Illuminated when Safety No. 2 reaches i ts UP limit. ) l
- 4. Record the flux monitoring instrument readings for each channel 1 l
and determine the ratio of Safety Rods UP readings to the readings' ~ l recorded in step C.3 above. Compare with data obtained on l previous startups to accertain proper flux level and ins trument behavior.
11 -
- NOTE If an Estimated Critical Position (ECP) has been calculated to pre-position the Fine Rod at other than i 15 cm, or to preposition the Coarse Rod and achieve cri ticali ty using the Fine Rod, omit steps 5 and 6 and proceed with steps 7a and b.
- 5. Insert the Fine Rod to 15 cm (near the center of its operating range).
- 6. Insert the Coarse Rod in slow speed to achieve criticality.
7 Applicable to startups for which an ECP has been calculated: '
- a. Insert the Fine Rod (Coarse Rod) to the pre-determined position. j
- b. Insert the Coarse Rod (Fine Rod) to approximately 2-3 cm. below the caluclated critical position and allow instrument readings to stabili ze. Then continue Coarse Rod (Fine Rod) insertion to achieve criticali ty.
- 8. When cri ticality is suspected, withdraw the neutron source and establish a constant neutron level (infinite period) at the desired power level.
9 Record rod posi tions, flux moni toring instrument readings and reactor period. These readings should be compared with previous cri tical data and/or the calculated ECP (if applicable) to verify proper reactor operation. 4. S

e, IV. Cri tical Operation ., A. Precautions
- 1. Observe precautions lis ted in Operating Procedure .No.I.
- 2. The Coarse Rod worth us about 1.2-1.4 % , the Fine Rod t
worth about .15 .32 % $. B. Procedure
- 1. Normal Operation
- a. The reactor is in general controlled with the Fine Control Rod. This is nost easily done using slow speed; however, the speed and control rod selected is at the discretion of the operator and will depend upon operator experience and ability. -
- b. If criticality is being maintained wi th the Fine Rod at less than 8 cm., the Coarse Rod should normally be withdrawn such that the Fine Rod may be inserted to an operating posi tion. In the range of 10 - 20 cm.
- c. If criticality is being maintained with the Fine Rod inserted more than 22 cm., the Coarse Rod should be inserted such that i the Fine Rod may be withdrawn to an operating position in the range of 10 - 20 cm.
- d. The 1inear micromicroammeter (channel 3) should normally provide the most sensitive Indication of changes of power level; however, it should be frequently cross-checked with channels 1 and 2.
- 2. Power Level Changes
'a . Power Level may be increased by insertion of elther the Fine of Coarse Control Rod depending upon the desired reactor period. Normally, the neutron flux is steadled at the new power level by manipulation of the Fine Rod.
- b. Power Level may be decreased by wi thdrawal of either the Fine or Coarse Control Rod. Normally, the neutron flux is steadled at the new power level by manipulation of the Fine Rod.
13 -
- c. If moderator or fuel is inserted into the reactor, or if an absorber is withdrawn, the reactivity will increase. The control rod (s) should be withdrawn and withdrawal coordinated with the insertI6n of approved material such that mininal perturbations to power level are incurred. Such an evolution requires that the potential reactivity worth of the control rods and the material to be inserted be known. If the neutron flux level increases at a rate faster than can be compensated for by control rod withdrawal, a Manual Scram shall be immediately ini tiated.
- d. If an absorber is inserted or moderator is removed, the reactivity will be negative. It is not necessary to follow this change with a control rod; however, if it is desired to maintain a given power level, then control rods should be inserted as necessary and Rod movement coordinated with the negative reactivity insertion, created by the approved material, in order to minimize power level perturbations.
O e 4 9 e
f. t . V. Reactor Shutdown A. Shutdown Procedure
- 1. To perform either a normal or emmergency shutdcwn, depress the red SCRAM button on the motor control panel, i 2. Observe the following:
- a. Scram alarm Indicator light and bel ENERG1 ZED.
- b. Magnets ON lamp DEENERGlZED.
- c. Engaged lamps OEENERGlZED.*
- d. Up Ilmit lamps remain ENERGlZED.*
[ e. Neutron level decreasing.

- g. Coarse and Fine Rod digital position indicators returning to zero centimeters, (indicates magnet carriages are being driven down).
i
- NOTE The engaged lamps will remain deenergized and the UP limit lamps remain energized until the magnet carriages have been driven to their lower limi t. At the lower limi t, i the Engaged larps and DOWN limit lamps should energize, and the UP limit lamp should de-energize.
3 Monitor the decreasing neutron flux level by changing the Range
, Selector swi tches for channels 1 and 3 l
- 4. If the reactor is 'not to be immediately re-started, or if the console is to be lef t unattended, carry out the Shutdown Check- l off procedure.
)
- l 15 -
L B. Shutdown Checkof f Procedure
- 1. When all reds are fully withdrawn and the magnet carriages have been returned to their DOWN limit, deenergize reactor power by depressing the STOP button on the console.
- 2. Lock and remove the key from the console key switch.
3 Record the stable neutron flux level for Channels I, 2, and 3 Place the strip chart recorder to Standby.
- 4. Install and lo'ck the Cadmium shutdown rod into the Glory Hole.
I 5 Check the reactor skirt door's and console doors locked, and announce that the " Reactor is secured" to nearby persons. NOTE The neutron flux monitoring instruments and area radiation monitoring systems should normally remain energized. ' l e

V. Reactivity Excursions and/or High Radiation A. Precautions
- 1. In the very improbable event of an uncontrolled nuclear excursion there is extremely little chance that at least one of the instrument scrams will not shut the reactor down. However, the reactor, in a very fast runaway, will actually shut itself down by its negative temperature coefficient. The occurrence of such an incident will be indicated by a reactor scram and actuation of the automatic high radiation and evacuation alarm.
~
- 2. If sufficient energy is released during the reactivity excursion to melt the Thermal Fuse, the lower reactor core half will drop approximately two inches and separate the assembly into two sub-critical masses. Subsequent startup will not be possible.
! 3 If an alarm from the Area Gamma Monitor (no reactivity excursion) is suspected as being the resul t of monitoring instrument mal-function, the alarm should be treated as valid until the absence of a radiation hazard is verified. B. Procedure
- 1. Positive Reactivity Excursion with no Apparent High Radiation levels
- a. If a positive reactivity excursion results in a power level greater than 100 milli Watts but less than the scram setpoint, immediately withdraw the Coarse Control Rod to reduce power to 100 milli. Vatts or less.
- b. If a positive reactivi ty excursion occurs at a rate such that Coarse Control Rod withdrawal is insufficient compensation, or if the origin of the power level increase is unknown, immedia tely scram the reactor in accordance with the Shutdown Procedures.
Further operation of the reactor will not be permitted until approved by the Reactor Supervisor and the Reactor Administrator.
- 2. Abnormal Reactivity Excursion and High Radiation Levels
- a. Immediately scram the reactor, push the Stop button, and remove the console key.
- b. Carry out procedures delinated in the General Emergency Procedures as described in the final Safety Analysis Report.
3 Area Gamma Moni tor Alarm (No reactivi ty excursion)
- a. If operating, shutdown the reactor in accordance with the .
Shutdown Procedures.
- b. Evacuate all pe'rsonnel from the Reactor Room.
- c. Immediately notify the Radiation Safety Office, the Reactor l l
Supervisor, and the Reactor Administrator.
- d. Conduct a radiation survey of the Reactor Room and, if !
applicable, the Centrol Room to determine the source of radi a tion .
- e. Further access to the affected area should be restricted until
- authorized by the Radiation, Safety Office.
