SUMMARY
1 July 1989 through 30 June 1990 I The following table and discussion summarize reactor operations in the period 1 July 1989 through 30 June 1990.

at 10MW Sched. Time for Yr. at 10 MW l *MURR is scheduled to average at least 150 ho irs oer week at 10MW.
Total time is the number of hours in a month or year.
During the months of October and November (October 29-November 6).
the reactor was shut down for an extended period of time. 7.15 days, to I replace the beryllium reflector. During the maintenance outage, four (4) graphite wedges were also replaced and various in-pool valves were rebuilt.
The extended shutdown accounts for the low percentage of total operating l time during these two months: 81.85% for October and 73.42% for November.
There were 30 unscheduled shutdowns recorded during the year 1 July 1989 through 30 June 1990. Only 8 were in the last six months, which I- 1 I
l .
could be attributable to the UPS being installed in October 1989. Of these shutdowns,10 were Rod Run Ins (RRis) and 20 were scrams.
Seven of the unscheduled shutdowns (2 RRIs and 5 scrams), were due to a Nuclear Instrument drawer, detector or detector cabling failure generating a I spurious shut down signal (no actual high power or short period was indicated). A bid package is being prepared to upgrade this instrumentation and a request was made to DOE for money to support this upgrade. We l anticipate that integrated cable detectors and new Nuclear Instrumentation will solve the spurious scram problems.
Of the remaining 23 unscheduled shutdowns, nine were component failures, six were due to loss of electrical power to the facility, five were due l to personnel errors, and three were initiated by the duty operator in order to repair equipment.
July 1989 I The reactor operated continuously in July with the following exceptions: five shutdowns for scheduled maintenance and refueling; and six unscheduled shutdowns.
I On July 3, a reactor scram occurred while shifting the wide range I switch upscale during a normal reactor startup. Electronics technicians used a current source to simulate input to the wide range monitor (nuclear instrument channel #4), but could not reproduce this problem. The cause l was suspected to be a sticking relay contact in the feedback network of the picoammeter module for channel #4. The wide range switch was cycled I through its full range and the picoammeter relays operated normally. A normal startup was completed with no further problems, g On July 4, a rod not in contact with magnet rod run-in occurred when control blade "C" disengaged from its magnet during routine shimming. The control blade drive mechanism was removed and the upper guide tube was I realigned to center the amil. The surface of the amil was cleaned. A hot reactor startup was then completed with no further problems. On the next I maintenance day, the offset mechanism and guide tube for control blade "C" was thoroughly inspected and further refinement of the alignment. was accomplished. The control blade was then pull-tested satisfactorily.
I l2 I
l -
l On July 18, two reactor scrams occurred due to momentary site electrical power interruptions which occurred during a thunderstorm.
I These interruptions were verified by the power plant.
On July 28, the reactor was manually scrammed upon discovery of a ;
- g leak from primary heat exchanger 503A. After noticing an unexplained l decrease in the primary pressurizer water level, the duty shift supervisor
'I immediately made a brief visual inspection of the mechanical eqtJpment room and discovered water leaking from the end cap flange of primary heat exchanger 503A. The control room operator was instructed to immediately scram the reactor, Coincident with the manual scram, the duty operator l
noted that a rod not in contact with magnet RR1 was annunciated and that the natural convection cooling valves (546 A/B) were open. It is believed l that an unannunciated Power Level Interlock scram from the core DP transmitter 929 occurred just shortly before the manual scram duo to a l I pressure dip caused when the leakage from the heat exchanger increast t.
After the manual scram, a Power Level Interlock scram locked in en the I annunciator which was initiated by core DP transmitter 929. I I Subsequent investigation of the heat exchanger revealed a tear in the I end-cap gasket. 'Ihe flange surface was cleaned and the gasket was replaced. The reactor was then returned to normal operation. '
g On July 30, a reactor scram occurred due to a complete loss of site l electrical power. The emergency generator started immediately and assumed its electrical load satisfactorily. The power loss was caused by a l severe thunderstorm. Site power returned after approximately 45 minutes and the reactor was refueled and returned to normal operation.
i E Major maintenance for J 11y included: installing a new bellows seal and bearings on pool demineralizer pump 513B; removing. taking measurernents l on, and reinstalling the Nuclepore irradiator case: and replacing the endcap gasket on primary heat exchanger 503A.
&lgnELlRSS The reactor operated continuously in August with the following exceptions: four shutdowns for scheduled maintenance and refueling; three unscheduled shutdowns: and one power reduction to examine the Beamport I "F" valve arrangement.

l On August 15, a rod not in contact with magnet rod run-in occurred when control blade "B" disengaged from its magnet during routine 1 I shimming. The drive housing for this control blade was removed, the magnet and anvil vere inspected and the guide tube was realigned.
i i
Electronics technicians subsequently checked and verified the continuity of I l the drive mechanism amphenol connector. A hot reactor startup was completed and the teactor was returned to normal operation.
On August 22, a manual rod run in was initiated to allow investigation of an observed water leak in'the mechanical equipment room. ne small g leak was determined to be coming from a sensing line for primary flow 1 element 912E. The reactor was subsequendy manually scrammed to allow repair of.this line. Machine Shop personnel removed a secuon of tubing I where the leak occurred and placed a compression coupling in the sensing line to rejoin the sections. No more leakage was observed and the reactor was refueled and returned to normal operation. This entire sensing line was I replaced on the next maintenance day.
- l. On August 31, a reactor scram occurred from what was believed to be a spurious reactor loop low flow signal initiated by primary flow element I 912E. The annunciation for this scram was reset before it was adequately documented by the duty operator, therefore the " white rat" scram monitor was used to help determine the most likely cause. It was determined from l scram monitor indications that the most likely cause was a reactor loop low flow signal from primary flow element 912E.
]
One of the sensing lines for this element had been replaced three days previously and it was thought that the transmitter may not have been adequately vented at that time, thus allowing entrapped air to indicate spurious flow oscillations, he transmitter was vented and a i compliance check for that particular scram was completed satisfactorily.
l The reactor was then refueled and returned to normal opam%n.
I Major maintenance items for August included: replacing the 6" discharge line gasket on pool heat exchanger 521B; testing the operability and placing on service the new diesel emergency generator; installing new l bearings and mechanical seal on primary demineralizer pump 513A:
replacing sensing line for primary flow element 912E; installing bismuth /
indium filters in Beamport "F" centertube; removing pool pump 508B to the I Machine Shop for repair; and replacing nuclear instrument channe: #4 detector (wide range monitor) on two separate occasions.
I l-4 y I
'I Seotember 1989 1
The reactor operated continuously in September with the following '
Ll exceptions: four shutdowns for scheduled maintenance and refueling: and five unscheduled shutdowns.
On September 3, a reactor scram occurred from what was thought to i be a spurious reactor loop low flow signal initiated by primary flow element ig 912E similar to the unscheduled shutdown of August 31. The annunciation for this spurious signal did not lock in on the annunciator board, so the
" white rat" scram monitor indications were used to help determine the most likely cattse. The transmitter was again vented and a compliance t
check for that particular scram was completed satisfactorily. No further g problems of this nature were experienced.
On September 5, a nuclear instrument channel #4 (wide range l monitor) high power scram occurred during a normal reactor startup. No actual high power condition was indicated on any other instrumentauon.
After troubleshooting efforts, the Electronics technicians subsequently lI replaced the channel #4 compensation potentiometer and the detector and no further problems have occurred.
I On September 0, a reactor scram and isolation was initiated by the ig area radiation monitor exhaust air plenum alarm unit, All personnel exited 3 the containment building as per procedure. All indications from the remote area radiation monitoring station in the Electron!cs Shop read downscale, l ig which indicated a probable electrical problem with the area radiation monitor. A Health Physics technician and the shift supervisor reentered the containment building with a portable radiation monitor and found all l
,l radiation readings in the containment building at normal background. An l Electronics technician determined that a failed resistor in the high voltage '
circuit of the area radiation monitor had caused the scram and isolation.
- The resistor was replaced and the area radiation monitor was tested satisfactorily.
I On September 18, a nuclear instrument channel #5 (power renge l
i I monitor) high power rod run-in occurred shortly after entering automatic control during the completion of a normal reactor startup. Immediately prior to the rod run-in, channel #5 was indicating 109%. 5% below the rod i
g run-in set point of 114% As an operator shimmed the control blades out, channel #5 indication rose to the rod run-in trip set point of 114% before I I-5 I .
I !
the automatic insertion of the regulating blade compensated. He rod run-in trip point corresponded to an actual power level of 10.4 MW. ne power i level indications on the two other power range monitors were within normal !
5 operating limits. The rod run-in was reset and the indication for channel #5 was lowered to match the other power range monitors before the reactor '
l was returned to normal operation. The operator involved was instructed to be more aware of his power indications while shimming control blades, l On September 25, an anti-siphon system high level rod run-in occurred soon after completion of a normal reactor startup. The rod run-in
.g was a result of a combination of an air leak at a fitting on the anti-siphon i pressure tank and water leaking by the seat of anti-siphon valve 543B. The i valve 543B actuator had been worked on during the maintenance day 1 l' preceding this startup and it appeared that the actuator was not completely closing valve 543B, allowing water to leak by its seat. The combined loss of
)
I air pressure and the valve leakage allowed water to accumulate in the a' arm sensing leg which resulted in the rod run in. ne stroke for the valve 543B l was readjusted so that the valve closed properly and the leaking air fitting
~
on the anti-siphon tank was tightened. The reactor was then returned to l normal operation.
1 The annual emergency preparedness inspection was conducted by Nuclear Regulatory Commission Inspector, Jim Patterson, from September i 26 through September 28.
j Major maintenance items for September included: replacing inboard / i outboard bearings and mechanical seal on pool pump 508B: replacing compensation potentiometer and detector for nuclear instrument channel i I #4: installing new relay K-58 in the N.I. channel #4 downscale annunciation circult: replacing failed resistor in the high voltage circuit of the area radiation monitoring system; replacing inboard / outboard bearings and )
-l mechanical seal on primary demineralizer pump 513A: rebuilding the actuators on valve 546A (in-pool heat exchanger) and valve 543B (anti-I I siphon).
October 1989 The reactor operated continuously in October with the following exceptions: six shutdowns for scheduled maintenance and refueling; and two unscheduled shutdowns.
> I-lI l l-6
I i On October 10, a nuclear instrument channel #5 (power range l l monitor) high power scram occurred during a normal reactor startup. No j lE W actual high power condition was indicated on any other instrumentation. )
Electronics technicians subsequently discovered, and replaced, a failed dual l trip unit in the drawer for this channel. A normal startup was then '
completed satisfactorily.
l On October 23, a nuclear instrument channel #2 (intermediate range I monitor) period scram occurred during a normal startup when the drywell for this detector was inadvertently bumped while operators were attempting ,
g to physically adjust the drywell for an adjacent detector. The clamps j securing the drywell for this detector were tightened and the operators i involved were instructed to be more careful when working around sensitive !
-l equipment. A normal startup was then completed and the reactor was returned to normal operation.
The reactor was shut down at 2200 on October 29 to commence special maintenance procedure #11 which includes replacement of the !
l rear: tor beryllium reflector. This maintenance outage was successfully l completed and the reactor was returned to full power operadons at 1630 I g November 6,1989.
3 l This extended maintenance outage to replace the beryllium reflector g and four graphite reflectors was accomplished in seven days as opposed to the nine days it took to replace the beryllium reflector in 1981. The l g- experience, tools and knowledge gained during the 1981 beryllium I (3. changeout assisted the planning and preparation for this changeout and resulted in a 9 manrem dose savings (see Annual Report Section IX for l lg Health Physics Summary).
l To change out the beryllium reflector, the reactor pressure vessel had
[l to be dismantled to the split ring flange and to replace the four graphite L reflectors three beam tubes had to be pulled back approximately ten inches.
Lg During the course of the maintenance outage, the valve actuators for i W V507 A/B and V509 were also rebuilt.
l Major maintenance items for the month included: rebuilding the actuators for anti-siphon valves 543A and 543B, and for in-pool heat J
l exchanger valves 546A and 546B: renewing the power connector for control blade "D": replacing the dual trip unit in N.I. channel #5 drawer: removing Beamport "F" centertube: removing the (saddle) air cans in Beamport "A": j 1 '

I !
l loading spent fuel elements in the National lead fuel shipping cask and transferring them to the beamport floor for temporary storage; replacing I two thrust bearings and one line bearing in pool pump 508A: connecting reactor control instrumentation and back up door power to the new uninterrupuble power supply (UPS) and placing the UPS on service: !
- g rewiring the Elgar AC line conditioner for standby operation and removing from service: and commencing special maintenance procedure #11 which includes replacing the reactor beryllium reflector.
I November 1989 The reactor operated continuously in November following completion l of the extended maintenance outage with the following excepuons: three
.l shutdowns for scheduled maintenance and refueling; and four unscheduled shutdowns.
1 On November 6, a reactor loop low pressure scram occurred during a _
low power (5 kilowatts) test to perform rod worth measurements, when tne l
l primary demineralizer loop isolation valves (527E, 527F) were opened. The demineralizer loop had been isolated and depressurized to change the I demineralizer prefilters. When the isolation valves were opened after completing this task, a slight (momentary) pressure drop was detected at primary pressure transmitter 943 due to its close proximity to the 4
demineralizer inlet isolation valve (527E), thus inidating the scram. This task is usually, though not always, completed with the reactor shut down and ;
the primary system depressurized. In cases where the primary system is l pressurized, the demineralizer prefilters can be isolated locally with manual Isoladon valves without using the air-operated loop isolation valves (527E, I
. I 527F). This results in depressurizing a small portion of the demineralizer loop volume (one filter bank) instead of the entire demineralizer loop. )
l
( These local manual valves can then be operated slowly to prevent significant pressure changes. The operators involved in this particular case were instructed to follow the accepted method for performing this task with the '
primary system pressurized.
On November 9, a nuclear instrument channel #3 (intermediate range g monitor) period scram occurred while the reactor was operating at a steady state 10 MW. No actual power transient was indicated on any other nuclear instrumentation. The intermediate range short period rod run in and I scrams are designed to assure protecuon of fuel elements from a continuous startup rod withdrawal accident (HSR. Add. 5, Section 5). If an actual power I
I-8 I
4 I transient had occurred at 10 MW, the three power range instrument scram and rod run-in trips would have occurred before a short period trip could occur, The channel #3 detector drywell and the surrounding pool area were ]
l visually inspected with no unusual indications noted. A front panel check of l channel #3 was completed, no electrical anomalies were indicated, and this
'g parucular problem could not be duplicated. The reactor was subsequently 5 retumed to normal operadon with no further problerns of this nature. 1 g On November 14, both of the operating secondary coolant pumps shut {
down when their substation power supply breaker tripped due to a thermal l overload, his occurred when the motor for secondary pump #2 drew l excessive current and its local breaker failed to trip, which then caused the )
substation breaker to trip. His substation breaker supplies power to the i
I local breaker panels for secondary pump #2 and #3. The primary coolant inlet temperature then rose to the high temperature scram set point of
! 148'F in approximately two minutes, causing a reactor loop high temperature scram. The operators involved in this particular situation did i not respond quickly to the changing temperature because they were I lg occupied with determining the cause of the loss of secondary flow. They have since been instructed that in this situation, the standard operating procedure calls for a manual reduction in reactor power if full secondary

l December 1989 g The reactor operated continuously in December with the following
.W exceptions: four shutdowns for scheduled maintenance and refueling; and two unscheduled shutdowns. .
On December 2, a nuclear instrument channel #5 (power range monitor) high power scram occurred. No actual high power condition was I I indicated on any other instrumentation. Channel #5 is one of three power range monitors, all of which will indicate any actual high power condition g and will respond by rod run in or scram. Electronics technicians subsequently discovered, and replaced, a failed trip module in the drawer ,
for this instrument. The reactor was then refueled and returned to normal ;
j operation. ,
On December 11. a rod not in contact with magnet rod run in I. occurred when control blade "B" separated from its magnet during a normal <
reactor startup. The reactor was subcritical when this occurred. The rod l drive amphenol connector was checked and the magnet strength was tested (
sausfactorily. The anvil surface was cleaned and the pull rod was centered within the guide tube. A normal startup was then completed with no further I problems of this nature, g Major maintenance items for this month included: replacing the drawer trip module on channel #5: installing a new breaker on secondary pump #2 controller assembly: Installing a spare trip actuator amplifier in the l rod run-in pos!Uon; and replacing the source range monitor detector.
. January 1990 The reactor operated conunuously in January with the following l- excepdons: six shutdowns for refueling and/or maintenance; and two unscheduled shutdowns.
On January 1, a rod run-in occurred simultaneously with the acknowledgement of an S-1 on limit annunciation. S-1 is an automatically
'g operated hydraulic valve which allows secondary water to bypass the primmy heat exchanger according to temperature demand. An annunciation for this valve occurs when it reaches 20% of its full open or full closed postuon. No unusual or abnormal indications were seen or recorded on any instrumenta-tion at the ume of the rod run-in. After examining all reactor indications
'I l 10 I
I ;
i l and finding no apparent cause, the rod run in was reset and the reactor was returned to normal operation. 'Ihe S-1 annunciation was felt to be coincidental and the rod run in was considered spurious. I On January 31, a manual rod run in was mitiated by the shift ;
g supervisor after observing the channel 5 and 6 power range indications i drifting down below 95% power. The problem was isolated to channel #4, the wide range monitor. This channel is part of the servo mechanism that I automatically maintains reactor power at a preset point. The detector for j this channel was replaced and its drywell was repositioned. The reactor was j g subsequently returned to normal operation.
Major maintenance items for this month included: installing a new air ,
l can in Beamport "A"; installing a new ce' . 'rtube with silicon filters in Beamport "F"; and replacing channel #4 detector (twice).
l February 1990 l The reactor operated continuously in February with the following I exceptions: four shutdowns for refueling and scheduled maintenance; one shutdown for refueling and a Nuclear Regulatory Commission reactor I operator startup examination; and two unscheduled shutdowns.
g On February 1, a reactor scram occurred when a Campus Facility electrician inadvertently opened breaker #2 on the uninterrupuble power supply (UPS) electrical distribution panel #1, while attempting to secure the l breaker for a wall heater in the UPS room. Breaker #2 on the UPS distribution panel #1 supplies power to the UPS. The UPS supplies condluoned power to two distribution panels located in the reactor control '
I room, which, in turn, supply reactor control and instrumentation power.
The opening of breaker #2 and the subsequent momentary loss of control l and instrumentation power caused the scram. The breaker was immediately reset, restoring power. A pre-criucal startup checksheet was completed and the reactor was returned to normal operation upon completion of a hot I- startup. The Campus Facility supervisor of the electrician involved in this incident was informed and the situation was discussed among Reactor l Operations and Campus Facility personnel.
I On February 26. a manual rod run in was inidated by the shift super-visor when no automatic rod run-in occurred subsequent to receiving a channel #4 high power rod run-in annunciation and drawer light. No actual I l-11 I

i I high power condidon was indicated on any instrumentation prior to or at the time of the annunciation. An electronics technician isolated the I
problem to the dual trip unit for channel #4 (wide range monitor) which he !

subsequently replaced, ne dual trip unit in channel #4 provides a signal 1 indication for the annunciator and drawer light and a separate signal for the l trip functions (rod run in and scram). The electronics technician I determined that the signal leg for the annunciator and drawer light was f defective and created a spurious annunciator and drawer indication. Before i replacing the dual trip unit, a test of the operability of the rod run in and I scram trip funcuons for channel #4 indicated that the trips operated i
satisfactorily and in their intended manner. After completing a pre-cridcal ll checksheet, which includes a check of all nuclear instrument channels, the reactor was returned to normal operation with no further problems.

June 1990 g ne reactor operated continuously in June with the following exceptions: four shutdowns for refueling and scheduled maintenance:and three unscheduled shutdowns.
On June 6, a reactor scram occurred due to the loss of facility I electrical power during a severe thunderstorm. Site power was restored to the facility in approximately fourteen minutes. At the onset of this electrical outage, the emerency generator started satisfactorily and assumed its l electrical loads. It vras discovered, however, that a main facility exhaust fan (either EF-13 or EF-14) was not operating. EF-13 and EF-14 are redundant.
I 100 horsepower motor driven exhaust fans-either fan will start upon the failure of the (operating) fan. Electronics technicians discovered blown fuses in the control circuits for both fans. He fuses were replaced and an j exhaust fan was started. An emergency generator load test (Compliance Procedure #17) was cerformed and the exhaust fan operated satisfactorily.
The reactor was subsequently refueled and returned to operation.
On June 14, a reactor scram occurred due to the momentary loss of facility electrical power during a severe thunderstorm. Again it was discovered that the ma' saust system was not operating and that the control power fuses for eacn fan were blown. The fuses were replaced and l an exhaust fan was started. An emergency generator load test was I I-13 g 1
I
- l performed satisfactorily and the exhaust fan (s) operated properly. 'Ihe reactor was refueled and returned to operadon.
Exhaust fans EF-13 and EF-14 and their associated controllers are part of a facility ventiladon system upgrade completed in October of 1989.
,g After consultation with the system design engineers and the controller vendor the following modifications were suggested to alleviate the fuse problems: separating the voltage source for control power to each fan so
- l that power for each fan is developed across different phases; increasing the
, amperage rating of the control fuses from 3 amps to 6.25 amps for each fan
'g which would also require replacement of the 480V/120V transformer a currently rated at 250 VA with one rated at 750 VA. The first modification has been completed. The second modifleation has been completed on l EF-13 and will be completed on EF-14 when a second control power transformer arrives. ' A Licensee Event Report was sent to the Director of ~
lg Nuclear Reactor Regulation on July 6,1990 detailing these unscheduled Ig shutdown events and the subsequent corrective actions, g On June 18, a rod not in contact with magnet rod run-in occurred when control blade "A" disengaged from its magnet during a normal startup. ,
The reactor was subcritical at the time this occurred. The anvil and magnet !
were checked and cleaned and associated wiring was inspected. Rod alignment to the offset tube was checked. No anomalies were noted. A normal reactor startup was then completed with no further problems of this type.
Major maintenance items for this month included: removing the l silicon filter centertube from Beamport "F" and installing the iridium /
bismuth filter centertube: replacing the control power fuses on exhaust ~.w EF-13 and EF-14; replacing the reactor temperature (Tc ) multivolt I. transmitter: repairing worn leads on the Th RTD for the in-pool heat exchanger; and replacing the control circuit transformer on EF-13.

1.4.9 Radiation Safety ]
The Shif t Supervisor is directly responsible for the overall safety of personnel on his shift and indirectly responsible for ,
all peiaonnel whose safety may be affected by activities con-ducted under his supervision. Radiation safety is a very im-portant part of this responsibility. It should not be construed that surveys, monitoring, or other measurements to check for contamination or radiation are to be made by operations person-I nel, but rather that the Shift Supervisor is responsible to insure that through coordination with the Health Physics person-i nel, adequate protection is provided for evolutions conducted lI i
during his shift.

I 11'.1.6 Reactor Shutdown Procedure I A ~. The procedure for a routine reactor shutdown requires only that the manJai rod run-in circuit be activated. However, prior to shutting down the reactor:
- 1. Turn on the source' range recorder and time and date-the chart.
- 2. Insert the fission chamber until a count'of approximately 105 cps is obtained on the SRM recorder.
- 3. Place the IRM recorder in fast speed and time and date
- the chart.
- 4. Take a set of nuclear and process data.
B. Depress the manual rod run-in button on the control console.
' Enter the time of shutdown in the log book.
C. Follow the reactor power decrease by changing the range-selector switch so as to keep channel WRM-4 on scale.
D. Complete the Reactor Shutdown Checksheet if the control room '. ]
.is to be left unattended for an ' extended period. ]
E. Ensure that the-primary and pool systems-are shutdown as per S0P IV.2 and V.2 respectively if the control room-is left
- unattended for an extended period of time.
11.1.7 Reductions in Power
- The procedure for reductions in power to perform short evolutions-(<- 45 minutes) such as Room 114 entry. shall be as follows
A. Turn on source range recorder and time and date chart.
B. Inset fission chamber until a count of approximately 10s cps is obtained on SRM recorder.
C. Place IRM recorder to fast speed and time and date the chart.
. Take a set of nuclear and process data, i
E. Depress the manual rod run-in button on the control console, i F. Drive control rods in 3" or to a height of 21" withdrawn, whichever corresponds to a lower rod height.
G. After evolution is completed, recover powt:r following pro-cedure for hot startup (11.1.2).
H. If the evolution for which the reduction in power b made exceeds or appears that it will axtend past 45 mirates, shut down the reactor following proceduce 11.1.6.
Rev.8/14/89_ App'd D SOP /Il-8 I .
i ag F. During' the process of' actually removing the offset, the core
's neutron levels will be continually monitored using the- t fission-pulse channel SRM-1. The reactor control room may i be unattended during the removal operation. All reactor l systems will be shutdown.
'. t 11.3.2 Caution Should be -Taken During Removal as Follows:
A. Due to the potentially'high radiation level produced by the activated blade, place the bridge arils to the upscale posi- -
tion to prevent a building isolation alarm while the offset is being handled near the surface of the. water.
gg B. Extreue caution should be used during Step II.3.3.L so that undue stress is not placed on offset mechanism'while breaking it loose from. guide pins. Also, extreme caution should be
) used while maneuvering the offset mechanism away from the pressure vessel.
11'.3.3 - The Detailed Procedure for Removal is as Follows:
A. Electrically disconnect the rod drive mechanism. ,
B. Remove the four bolts at the base of the rod drive mechanism and with either the rod magnet fully inserted or withdrawn, l remove the rod drive mechanism.
C. Remove the four bolts at the base to the rod' drive shaft housing assembly.

F. Verify that all the valve position indicating lights are
- operating. If not, replace the appropriate light bulb. If this does not clear the malfunction, determine the cause and make repairs prior to any reactor start up.
I.
NOTE: The following steps are at Shift Supervisor's discretion..
G. Turn off the pool flow and temperature recorders.
'H. Secure power to P508 A/B. ;
V.3 Partial Pool Filling Procedures (Pool at Refuet 1.evel or ' Above)
.V.3.1 To increase the water level in the pool with demineralized water j
- f rom T301 or T300, one of the two following procedures can be-
- used; hcwever, all water in T301 shuuld be used first.
.- A. Filling may be accomplished with the skimmer system (Section VII.S.3) with or without the skimmer pump operating and the reactor either cperating or shutdown. Required operational pool makeup will be accomplished in this manner:
- 1. Check capacities of tanks T300 and T301 and check proper valve lineup.
- 2. Observe the pool level and check that the skimmer pump is secured.

- 1. Using bolt removal toel, loosen offset rr ::hanism hold down -
; b'olt on rear of assembly.
J. The lifting and removal' of the offset can be accomplished by ] ; using a center pull lifting , rod, the J-shaped "T" lif ting ] L- - tool, or in some cases both tools. If using the' center-pull: ]
'i rod, thread the rod in snug and raise the- blade.to full out. - ]
If using the "T" lif ting tool, insert the pulli_ng tool into 3
.the hole in the counter balance arm and raise the blade to -]
l full out, then insert the "T" section of the lif t ' tool' into ] the lifting lug at the top rear of the offset. ] K. Attach the lifting tool to the crane. l L. Jog the crane while lifting by hand until the offset mecha-l nism lifts free of the side guide pins. Observe clo_se_ly_ the ] strain necessary to break the offset free. If the offset .l l . mechanism does not break loose from its reflector platform- l 1 L after' applying a reasonable amount of tension, relieve the l tension on the lifting tool and determine the reason for> the-h difficulty before continuing.the attempt to lift the mecha-nism. q M. After the offset mechanism has cleared the guide pins care- , fully raise it until' the top of the blade. mount is about' 1/8" '
~
below the pressure vessel intermediate-flange. NOTE: Af ter the mechanism clears the guide pins, the blade is still partially within the gap so caution must be observed to hold the mechanism steady while
- raising it to the flange above or the blade may be L damaged.
N. With the blade now clear from its gap, carefully move'the i mechanism away from the pressure vessel " spool" flange and ig E raise the mechanism to the surface. Rev. 1/16/90 App'd g_ SOP /Il-14
u l CAUTION: The lower portion of the mechanism and the-lower tip of the blade will be very radioactive,- ; so insure close Health Physics coverage is pro-K , vided before- raising the blade to the pool. water surface. I 11.3.4 Installation of the Control Blade Offset Mechanism L The procedure for installing the blade and offset mechanism is , essentially the reverse of the above, with a particular emphasis l on the following: points: . A. Before inserting the mechanism, check the clearance of the l blade gap with the gapping tool. B. After disengaging the lifting tool, the Shift Supervisor -- ] .
. or Senior Operator will exercise the blade over its full m
length of travel until he is convinced that the blade moves j l l freely and is able to travel through the gap totally without 1 resistance. C. During the subsequent pull for the rod drop test, determine
;g 3/ the position at which the photocell for the drop timer' . actuates with respect to the ' blade full-in ' position. It ; must not be greater than 5.2". . 11.4 Waste Tank Analysis A waste tank analysis is performed by the laborator) + ,s for O evidence of activity prior to release to the sanito sewer.
L See Section VII.8.6. A pH of each sample is measured to i determine its acidity. If the waste water is very Nidic (pH L less than 4) and the liquid waste is to be held, a caustic 1 . solution should be 'added and circulated to prevent excess corrosion of the waste tanks.

i I VI.6.3 Secondary Water pH Control
)
To control pH, water is sampled and monitored by the pH unit , located in the tunnel entrance of room 114. If the pH increases I above the system setpoint, the acid injection valves automatical-ly open and acid is gravity fed into the tower sump. The acid 1 used is concentrated sulfuric acid supplied from the 250-gallon j day tank in the cooling tower. J I VI.6.4 Sample Paths for pH and Conductivity I i , A. During normal operation of the secondary system, the auto-matic pH and conductivity control units receive their sample
~
water through valves S104 and S151. '; l B. During operttion of the secondary system with the air condi- ; l tioning units secured and isolated, close S104 and open S103. This provides a representative sample for these units to control pH and conductivity. ] . l C. The pH and conductivity units shut down when secondary pumps (P-1, P-2, and P-3) are secured. l l VI.6.5 Secondary Water Corrosion Prevention 1 The prevention of corrosion in the secondary system is
~
A. accomplished by automatic addition of a corrosion inhibiter, i B. These chemicals are fed automatically by a metering pump ) I. system based on makeup flow. , J u 1 Rev. 1/16/90 App'd m , SOP /VI-8 j

I VI.6.6 Secondary Silt, Algae and Hud Control Silt and mud buildup is controlled by the feeding of a chemical silt dispersant to the cooling tower basin. The dispersant is added to ensure solids remain suspended a sufficient amount of time to allow the secondary blowdown to remove them from the , system. This reduces secondary conductivity and minimizes the buildup of silt in low flow areas, a fouling condition. ! I Microbiological and algae growth is controlled by the addition of two microblocides/algaecides. The addition frequency is 3 determined by weather conditions and reactor operations.

l- a EVALUATION OF ENVIRONMENTAL IMPACT. OF INCREASED STACK RELEASE FLOW RATE' i Stack release limits set for MURR in Technical Specifica-tion (1) Number 3.7: " Facility Gaseous and Particulate Radio-active Release" are-based on activity concentrations. An increase in stack flow rate affects the total allowable release of activity, and thus this evaluation is made to
- I l~
. assess the environmental impact the increase will have on the nearest resident and on the population surrounding the MURR.
The change in stack height and exhaust exit path is also con-1 . sidered. The safety significance of the impact is discussed in relation'to background radiation and in relation to a previous environmental impact appraisal made by NRC. (2) I Data and lamustptiana I The data and calculations in Table 3 describe the physi-cal =information~of the stack release point. principal-isotope released in gaseous effluents from MURR. Argon-41 is the The Technical Specification limit for Ar-41 release is 350 I t times.the MPC listed in Appendix B, Table II,' Column I of

= (1.4 x 104 pCi/ min) (1x10-6 C1/ C1) (1 min /60sec) = 2. 4 x 10-4 Ci/sec In the previous environmental assessment, (2) the NRC used meteorological data collected at the Callaway Plant, located 'I. near Fulton. These data were collected between May 5, 1973 and May 4, 1975, and were judged by the NRC to be " reasonably representative of long-term conditions expected at the MURR ,
site." This current assessment utilizes meteorological data gathered in Columbia, MO from 1960 to 1969. (3) The Columbia data was judged to be more appropriate for use in assessing airborne releases from MURR because of the longer data period and the proximity of the data site to MURR. Table 2 lists E wind data (stability, class, speed and frequency) for each of ' the sixteen campus points. A-1

' Population' dose estimates were made assuming l ground release conditions. Population density data was generatedW- t
_using 1980 census data, 1985 update & n, and growth projec- , J : tions provided by City of Columbia oi .cials. Estimates for i population doses were based on the piajected 1990 population densities (See Table 6) . The max! um average annual dose was determined at the-center of each population zone, except for the 16 zones'at 0-1 miles. Because residences are no closer than 760 m, the midpoint was chosen at 0.75 miles (1200 m) from MURR. In LI' . L addition, radioactive decay was considered in these calcula- ; tions due-to the significant amount of time required for the
! plume to' move to these distances. Otherwise,_ calculations !I: were made as were the individual dose estimate calculations.
Data for c yand o, is given in Table 7, che summary of annual
.' ~ doses in Table 8, and the population dose estimate in Table
- 9. For the. population out to 10 miles, the maximum annual popula-tion dose is estimated to be 145 person-rem.

In the same NRC evaluation, the population dose for implementing Amendment No. 12 was estimated to be 20 person-rem. Although ' assumptions, data, and conditions for calculation are not fully. described in the NRC Amendment No. 12, estimated doses are greater than those predicted by the current assessment, which utilizes more realistic model (effective stack height
; and stability class weighting) and better site-specific data (meteorological data and updated population densities). The NRC concluded "that_there would be no significant environmen-tal impact attributable" to an increase in stack release I"- limit to 350 MPC. With lower doses estimated for the current change in stack height and flowrate, it is also concluded that no significant environmental impac exists. The same conclusion applies to instantaneous release limits.
Another method of assessing risk from the estimated
;g: doses is to compare them to natural background dose rates. 'g. The average whole body dose to an individual in the US is 360 mrem /y . (9) The estimated doses in terms of % of natural backgrcund are:

I SECTrlON 2.0- ANALYSIS OF A LOSS OF ELEURICAL POWER TO THE i MURR 2.1 Introduction ^ ',
'1his report contains an analysis of a complete loss of power at ~
the MURR, This implies a loss of commercial nower followed hv a failure of the emergency generator system. The L emergency generator system is described and the routine surveillance tests are outlined. Accident analyses will then be L presented for a complete loss of electrical power during a i period when the reactor is shut down. 2.2 Descrintion ,g Upon'a lo'ss of normal electrical power to the facility, the EG g- assumes the desired electrical loads. Drive power to the ' generator is provided by a Cuminins six cylinder, turbocharged l diesel engine. The engine is provided with a 270 gallon fuel storage tank and a mechanically driven fuel injection system. The EG is capable of assuming full load from a cold start in El 1 seven seconds. A 24 volt nickel-cadmium storage battery is ' used to start the EG. A static type dual rate float / equalizer charger automatically maintains the startup battery fully-LI charged. ( A four pole generator equipped with a brushless permanent magnet exciter produces 60 cycle 277/480 volt. 3-phase
.g service, and has a standby continuous load capacity of 275 KW, ,E! The design of the exciter and regulator provides voltage regulation of better than plus or minus 2%. Stable generator output voltage and frequency are established within two seconds after a transition from no loaa to full load conditions.

!2.4? Accident Analvata 2.4.1 Loss of Commerr ini Power with the Reactor Oneratina at -
i10 MW and the Rmeraency Generator F211a to Start Each system that is affected by a complete loss of electrical
; power is listed and commented upon in the following ~
paragraphs.
! (1) Reactor Control System At the time ofloss of commercial power while operating at 10 MW, the reactor would scram as a result ofloss of j ~. power to the electromagnets holding the blades in position. The blades would drop into the core by giavitational force and the reactor would be shut down.
(2) Reactor Process System ! All process systems (e.g., primary cooling, pool cooling, j etc.) will be placed in the shutdown condition to the yg. failsafe design of these systems. Ioss of electrical power g would cause a cessation of coolant flow cnd a closing of l- the isolation valves. In the primary system, redundant p I valves 546A and B open by spring actuation placing the in-pool heat exchanger in service. The fallsafe design of L the system permits shutdown decay heat removal vrith no
)h electrical power (reference: Appendix D of Addendum 4 i to Hazards Summary Report).
j (3) Containment Building Ventilation Isolation Doors . Power would be lost to the motor operated doors and. they would fail to close (or open) in response to any
- g; electrical signal. Also, the gasket seals would not inflate 3: since the inflating mechanism responds only when the-doors are closed against their stops. The backup cg isolation doors, however, fail closed upon loss of solenoid L
power and hence would automatically close upon loss of building power. g III-17
- l '
, (4) Emergency Air Comnressor - , l , g)l 'Ihe emergency compressor motor would fall to operate '3 in response to a falling pressure in the reserve tank. 'lhe- '
reserve tank holds a volume of 10.5 ft3at a nominal'~
"(; ~ -pressure of 100 psi, which would be sufficient to inflate all gasket seals on all isolation doors if this were ' "; g.- ,
required. Bct the ability to recharge the tank to nominal E operating pressure would be lost in the event of a , complete' power failure. The primary function of this compressor is to provide air to the seal gaskets of all
'l" . (-
isolation doors. Since the doors would not be operable
- g. with no. power there is little demand for the emergency ,
E, air supply. (5) Truck Entry Door: Door 101 Benmhole Floor During reactor operation and during periods when the ] ll l-reactor is left unattended, the door is closed and the seal is inflated.- Loss of commercial power would prewnt one . L from being able to open this door or deflate the' seal. r . IIence, loss of commercial power during normal reactor - operation would leave the status of this door unaffected. t l( u (6) Personnel Airlock Door: Doors 275/276 Grade Level' .! i During reactor operation and during periods when the:
- reactor is left unattended, one of these doors remains L ~
closed and the gasket inflated. Loss of commercial . power without the ability of the EG to provide emergency: power, would prevent one from operating these doors qk electrically. There is in existence, however, a procedure . i by which the gaskets can be deflated manually and the L doors manually opened or closed. Even though the doors L , cannot be operated electrically, it is possible for one to leave the building through these doors in the event of
- j. . ;
~
a power failure. However, the ability to maintain at least 4 one door in the closed position with its seal gaskets ,g inflated is lost if power to the doors is not available. The .E ^ containment integrity of the building, therefore, cannot j III-18 _ _ _ _ = _ _ _ _ _ - _ _ _ - _ - _ _ _ _ _ _ - _ _ _ _ _ _ - -
I Il , be' guaranteed if emergency ~ and electrical power were not available to operate both doors.' Howevet, the reactor g will be shutdown and containment is not a vital lB' requirement. ) , (7) imhorntory and Reactor Exhaust Fana: ' EF-13 and EF-14. Fifth Level West Tower h Upon isolation of the reactor building, the operation or inoperation of these fans would have no consequence on the status of the reactor building. Upon~1oss of commercial building power without the availability of
, emergency power, both of these fans would cease to (l function.
(8) Reactor and Imboratory Corridor and Exit Liahts
. The 120-volt corridor and exit lights in both the reactor l' building and laboratory building depend upon commer-cial power or emergency backup. In most areas, emer- .g; gency wall battery pack lights which operate upon loss of ;gL commercial building power provide sufficient lighting for . all personnel to leave the reactor building and laboratory g corridor areas safely. Visibility in all the strategic place-ment of these battery pack emergency lights. ;(9) Fan Failure Alarm System ;g The exhaust fans, EF-13 and EF-14 " failure to operate" >m; alarm system would not function. Loss of building commercial power and loss of emergency backup power .l. would prevent the operation of these fans as previously discussed. Such a situation precludes the need for these . alarms.
(10) Intercommunication System y I The laboratory area and the reactor building are provided with a muluple station intercommunication system. The
.; loss of this system results in the inability to transmit .l III-19 ,h

telephone communication to each laboratory area and- !
- g: . various areas inside the reactor building would not be . ;
2Ei interrupted by a loss of commercial power, There is also: provided portable battery-powered transmitter-receiver - l 4
. packs which can be 2 sed to maintain communication i ' ~
between the Emergency Director in the laboratory loaby j and investigation parties sent out from that area. f

(11) Reactor Bhilding Isolation and General Evacuation Marmi i, i Loss of reactor building power without emergency back-up power would result in the loss of all audible and visual t L( evacuation and isolation alarms. (12) Diesel Room Distribution Panel Power to the EG control panel, EG room lighting and EG : room temperature controls are provided by this panel.. Loss of commercial power as well an emergency power ' would leave these loads de-energted. However, failure of the generator engine to operp.te preempts the need for l these loads. l; (13) Ecactor Centrols and Instrumentation Power to all reactor instrumentation and controls, both 1
'l process and nuclev, is provided through a 120 VAC , 7 distribution panel located in the control room. Loss of comn.ercial power without emergency backup would not effect the control and instrumentation power for 20 -
minutes because of the capacity of the uninterruptable I power supply (UPS). Once the: reactor is confirmed to be
~
shutdown and before the UPS batteries reach a low l voltage. condition, the control and instrumentation systems would be secured. The UPS unit would be i secured prior to the batteries reaching a low voltage condition to prevent a low voltage transient on the system. The reactor operators would then have no control console information relating to changes in the I III-20

' status of reactor system different than that gathered * - when the UPS was operating. ' All' subsequent information regarding valve position and - the status of the reactor would have to be obtained visually by the reactor operator. With the reactor shut down and with system status known before securing UPS power, the reactor operator can monitor valve position ;gl B indications at the reactor bridge and the redaced intensity'of the Cerenkov glow in the region of the core.
Operation of the emergency pool fill system would be unaffected. 2.4.2 Loss of Electrical Power during Reactor Shutdown Periods The status of all systems would be identical to that discussed in paragraph 2.4.1 with the following exceptions: (1) Reactor Control System In this case it can be assumed that the reactor is in the shutdown mode with all systems secured. This would be
. assured by the fact that prior to the loss of commercial - (' power a complete shutdown checksheet for the reactor-and systems had been completed. Therefore, there would be no need for the reactor operator to determine 5 : the status of the reactor or reactor systems after the loss.
of commercial power. (2) Persons within Containment at the Time of Loss of
; Commercial Pmy,gr Research and other non-reactor staff personnel may be =
within the containment building at tk a time of the loss of commercial power. All personnel allowed un-escorted access to containment have a knowledge of how to
- l. operate the personnel airlock door manually without assistance at a time when electrical power to these doors g is unaval'able. Simple directions are posted next to the u airlock doors.
- I 111- 2 1 1
I (3) Containment of the Ranctor Buildina Containment integrity of the reactor building would be l assured by virtue of the status of the reactor during a normal shutdown period. Truck entry door 101 on the beamhole floor would be closed and sealed, the 16" building exhaust isolauon valves would have failed closed, the supply and return fan on the fifth level would have
~l' ~
stopped operating, the primary isoladon doors would remain open, however, the backup isolation doors would have failed closed. 2,5 Conclualons ! Under the postulated failures, the reactor will shutdown and l the core will be cooled indefinitely by natural convection circulation through the in-pool heat exchanger. It may be necessar" ::o violate containment briefly to allow personnel to ! enter and exit containment, however, the reactor is in a safe configuration. Health Physics monitoring with portable instruraents would preclude the accidental exposure of l personnel to radiation. I 'I o lI i I I 1

'Ihe need for a means of remote sampling of the containment j building (as opposed to having personnel enter into containment to sample) i I was recommended during a routine safety inspection by the Nuclear Regulatory Commission (NRC) on March 6-10, 1989. l
;g This modification utilizes the system originally installed to perform the reference volume method of determining containment buildmg leak rate. This system had not been used at MURR since 1978, w:.ien MURR l changed its method vf performing the building leak rate to the make up flow method. The reference cans for the reference volume system have I been disconnected to provide sampling points for the air sampling system (see Figures 1 & 2). 'Ihe safety evaluation for this modification documents that it does not present an unreviewed safety question as per 10 CFR 50.59.

I ' I ModlScation 88-6: Emergency Electrical Power Unnrade (replacing ! cmergency generator (EG) and automatic transfer switch) : This modification replaces the original 45 KW gasoline powered EG with a 275 KW, diesel powered generator. This change was made due to the I age of the original EG as well as its lack of capacity for anticipated facility modifications, he HSR sections changed by this modification are mainly descriptions of the EG and the Emergency Electrical Distribudon system. ! ne HSR section (Addendum 5, Section 2.0) that contains an analysis of a complete loss of electrical power at MURR, remains virtually unchanged ! except for descriptions of the new EG and Emergency Distribudon System. t ne surveillance tests for the new EG will be incorporated into the HSR and ' will meet or exceed technical specification requirements. The HSR Addendum 5, Section 2.0 analysis concludes that a complete loss of I electrical power creates no hazard to the health or welfare of the general public. We bases for Technical Specification 3.10 states that on loss of normal electrical power the EG is not required for protection of the fuel t l element integrity. ,g The probability of the occurrence of a malfuncuon in the new EG is 3 expected to be less than that of the original EG, which had provided 22 years of service, but had no capacity for future expansion of emergency , electrical loads (i.e. new exhaust ventilation fans). : The safety evaluation for this modificadon, summarized here, I h documents that it does not present an unreviewed safety question as per 10 CFR 50.59. Modi 8 cation 88-11: Reactor Control Power Unnrade t This modificadon replaces the Elgar line conditioner with an ' Uninterruptible Power Supply (UPS) to provide regulated reactor control power. The replaced Elgar line conditioner was not specified in the original I- Hazard Summary Report. The line conditioner was added as an enhancement to the 120 VAC electrical supply to the reactor control and instrumentation power supplies. l lI l IV-3 I
1 HSR Addendum 1, Section 3.5 addresses the reguladon required of j MURR instmmentation and control and specifies system tolerances to l electrical supply changes over the following ranges' i Supply Voltage: 115 Volt +/- 10% Supply Frequency: 60 Hz +/- 5% l Temperature: 32'F to 120 F ,g These regulation parameters provided the impetus to install the Elgar line E conditioner, which can regulate supply electrical power as follows: .! I Supply Voltage: Supply Frequency: 115 Volt +/ .05% 60 Hz +/ .05% ne UPS can provide regulation as follows:
+/- 1% of Nominal Voltage (115 VAC) , +/- 0.1% of Nominal Frequency (60 Hz) ne UPS cannot provide the absolute voltage reguladon of a line conditioner, but it provides regulation over a greater range ofinput voltages.
A line conditioner regulates small monitoring voltage fluctuations, whereas a UPS regulates the outrut for even a complete loss of input voltage. , The UPS will protect the reactor instrumentation and control power
- from line transients, line noises and during the transitional period between the loss of facility electrical power and when the Emergency Generator I assumes emergency loads (see flg 3). The safety evaluation for this modification, summarized here, documents that it does not present an unreviewed safety question as per 10 CFR 50.59.
Modification 88-7: Exhaust Ventilation Uoprade l This modification to the ventilation system replaces the original exhaust fans with two speed fans and 100 H.P. motors and adds an acid I scrubbing system for the silicon laboratory to remove nitric, hydrofluoric and acetic acids. The new exhaust fans increase discharge flow from 20,500 SCFM to 33,500 SCFM, which ensures all MURR fume hoods will have a l minimum of 125 LFM face velocity. These modifications also required the addition of two (2) new roof top air handlers (6,000 SCFM cach) to supply air to the facility. Modificadons to the fan failure and warning system have I also been accomplished. l IV-4 I
I The fast speed isokinetic probes for the stack monitor were installed on May 7,1990. The ventilation system was balanced on May 14,1990 and placed in continuous fast speed operadon on May 15,1990. I 'Ihis modification will be complete when the auxiliary heating system for the new roof top air handlers are modified and operationally checked. The safety evaluation for this modification documents that it does not present an unreviewed safety question as per 10 CFR 50.59. I I I LI I I I i I o I IV-5 L

This amendment temporarily increased the Special Nuclear Material I hwentory under Facility license R-103 pending the establishment of capability for the offsite shipment of spent fuel. As part of its annual reporting requirements, the status of establishing this spent fuel l shipping capability is described below: On April 18,1990, MURR submitted a request to the Nuclear Regulatory
.I Commission (NRC) to amend the BMI-1 spent fuel shipping package Certificate of Compliance to authorize MURR to use this cask. On July 6 1990, the NRC submitted four questions to MURR concerning our I- request. The answers to these questions are being prepared and will be sent to the NRC in mid August.
I A submittal was made September 12, 1986 pertaining to the new MURR I fuel design with associated revisions to the Technical Specifications. The fuel design has been evaluated by the NRC and Amendment No. 20 was issued August 1,1990 approving the new fuel design. A description l of this amendment will be provided in the 1990-1991 annual report. A request for a unique purpose exemption as defined in 10 CFR 50.2 I was submitted September 26,1986 and is pending.

I !l Miscellaneous Items-In December 1989, Mr. Ronald J. Dobey, Jr., Health Physics I Technician, completed his MBA degree and left employraent with the University to become an Agreement State Regulator in Kansas. Mr. R. I Mark Stumbaugh was hired as a Health Physics Technician in March 1990. Mr. Stumbaugh received his original training in the Nuclear Navy Program, followed by two years in health physics jobs at several nuclear power l plants. An additional Health Physics Technician position waa established and hiring for that position is underway. Ms. leslie M. Powell was hired - I into the newly established secretarial position to support the MURR Health Physics Group. She had been the MURR receptionist for over three years and was familiar with many of the secretarial needs of the Health Physics l Gmup. Three new Health Physics Standard Operating Procedures were I added. HP-34: "MURR Identification Badge Program and Implementation" was established to provide guidelines and policies for the use and issue of I identification badges at the MURR facility. HP-35: "Beamport Area Access" was established to define access controls for the area surrounding the beamports following the redefinition of the MURR neutron beams as high l radiation areas (see Inspection Report No. 50-186/89001). HP-36:
" Remote Sampling of Containment Air" was established to provide the I capability of sampling containment building air without entry in the cases where airborne contamination is suspected following containment isolation. Copies of these procedures are attached at the end of this section.
ADCO Services, Inc. has continued to act as our institutional waste broker. Through ADCO, MURR disposed of 798.9 cubic feet of LSA material generated at MURR. The replacement of the reactor beryllium reflector and graphite reflector wedges (see Section I) was accomplished with a total of 4.96
.k manrem exposure. The October 1981 changeout of the heryllium reflector had required 14 manrem to complete the job (see Operations Report I 1981/82). The prejob review and training utilizing the knowledge gained from this 1981 job helped to identify several ALARA measures which were implemented for the 1989 job: this accomplished a 9 manrem reduction.
I m.e I
I l l Review of dose received for the 1989 job have identified additional ALARA measures to be considered for the next scheduled beryllium reflector I changeout. A program to improve the docurr.9ntah. . :,onnel dose review g . for the purpose of ALARA assessment ?tas b # . . Afarch 1990. 'Ihis program has established ALARA reportit.g criteria and provided an 3
-improved mechanism for management review. As the program is being l established and tested, assessment is continuing in how to best fit the ALARA review process for the various working groups at MURR. ALARA I efforts to reduce extremity exposures in the production of radioisotopes used in radiopharmaceuticals at MURR have continued. Changes in the chemical compound of the target materials have allowed for reduced handling of these materials during processing, which has greatly reduced 1 the extremity exposures received per acuvity handled.

Purnene To provide guidelines and policies for the use and issue of identification badges at the MURR facility. III. ceneral Personnel at the facility will be issued I.D. badges based on I level of access, blue for containment access and orange for lab access. Personnel having containment combination access will be identified by a special hole punch in the white side of the badge. This will assist in maintaining positive I control of the combination. Along the bottom of the badge the individual's name will be printed. Temporary badges will also be available for use as spares and I- for personnel who have unescorted status but visit the site infrequently. These badges will appear much like the 3 permanently assigned badges with the following exceptions: in g place of a photo the word " TEMP" will be visible; and instead of a name a serialized number will be used for identification at the bottom of the badge. These will be maintained at the 'I Front Desk and in the Control Room and will be logged out as needed. Personnel requiring an escort will be recognizable by their I' lack of an I.D. badge. All personnul at the facility without an I.D. badge shall be escorted by badged personnel. IV.

$5.00 each subsequent replacement. Chronic loss or I forgetting of badges will be reviewed and could result in loss of access to the facility.
During non-working hours each person will be responsible for the safe, secure keeping of the issued I.D. badge. Badges shall be kept in a manner which will preclude theft or misuse of this identification material. They should not be
.g hung from rear view mirrors or left on car seats or in any 'g unsecured area where theft could occur.
At the time of termination of access to the MUR3 facility, the individual and sponsor will ensure that the I.D. badge is turned in to the receptionist for proper disposition. ,3 Any unescorted personnel inside the facility without an I.D. '5 badge shall be challenged and the Control Room notified of the unauthorized entry. The individual shall then be i 3 escorted to the lobby for interrogation by the receptionist ! l-g or reactor operator. This applies as well to a person with lab access I.D. badge found unescorted inside containment. V. Procedure The materials used to produce the badges will be assigned as
~g follows: ID camera and film to Health Physics; and the badge g blanks, lamination folders, die cutter, and lamination . machine to the Director's Office. The name or number will be !
printed by Kroy lettering. This will be done with cooperation ) between HP and the Director's Office. j Issuance of identification badges will be as follows: the I individual will be photographed following Indoctrination and this photo will be given to Direct <-- . .ece personnel for subsequent badge assembly. At this time the new personnel will be given a temporary I.D. badge while awaiting permanent LI l I.D. badging. The new personnel should normally receive their permanent I.D. badge within twL weeks. l The designation of combination access will be made by the Reactor Manager.
