Summary
Scope: This special inspection involved (90) inspection hours on site after
the reactor startup on May 17, 1985, when the reactor was taken critical below
the control rod insertion limits required by Technical Specification 3.1.3.6.
The predicted critical rod position was calculated to be 38 steps on bank D,
but actual critical position was 26 steps on bank C, which was below the inser-
tion limit of 47 steps on bank C. The primary source of error was attributed
by the licensee to be errors in the xenon calculation.
Results: Three violations were identified: (1) Technical Specification
6.8.1.a - Failure to follow procedure for Reactivity Balance Calculations
(Estimated Critical Rod Position OP/0/A/6190/06) and failure to follow
procedure for reactor startup (0P/2/A/6100/01 and OP/2/A/6100/05) (paragraphs
5.c and 5.d), (2) 10 CFR 50 Appendix B, Criterion V - Failure to review changes
to the Xenon Predict Program values used in estimated critical control rod
position calculations and shutdcwn margin calculations, (paragraph 5.e),
(3) Technical Specification 6.10.1.d - Failure to retain records of Surveillance
Requirement 4.1.1.1.1.e for calculation of shutdown margin (paragraph 5.f).

b. DiscussionofXenon(Xe) Values
Since the beginning of operation of McGuire 1 and 2 the licensee has
felt that the vendor (Westinghouse) underestimated peak and
equilibrium Xe values. This was based on past experience and surveys
of other utilities. A value different from the vendor peak value by
1000 percent millirho (pcm) was used for Unit 2 cycle two. The
values used for Unit 2 cycle two for peak and equilibrium Xe were the
same values used for Unit 1 cycle two, due to similar core designs.
Discussions with the corporate nuclear engineering staff revealed
that the general office usually underpredicts the vendor Xe values
and the plant reactor engineering group supplies a multiplier to the
general office values for values used in the plant computer. The
plant values are usually greater than the vendor supplied values.
The general office felt that the library of cross sections and decay
constants (EPRI library) used in their computer code (PDQ - a two
dimensional diffusion theory code) underpredicted the actual Xe
values in the core. Also, it was felt that the vendor estimates have
improved lately due to changes in the vendor codes and updated
library. This would account for the values used by the plant after
5/17/85 being similar to the vendor values.
Further checking by the reactor engineering group on 5/22/85 found
that the values used in Unit I cycle two were in error. The values
were changed in error in August 1984, based on an estimated critical
on bank D instead of the correct value using bank C. The Xe values
were changed to more closely predict estimated critical rod position.
This error was carried over into Unit 2.
c. Licensee Analysis of 5/17/85 Event Performed on 5/17/85
The previous calculations of critical position were checked and found
correct. Boron samples were also verified as correct.
The plant nuclear engineer assigned to handle the missed estimated
critical position concluded that the error was due to Xe. This was
based on several things. First, the startup on 5/8/85 was essen-
tially Xe free and no problems were noted. Other parameters in the
reactivity balance used to calculate critical position were recently
verified during startup physics testing (control rod and boron
worths). This startup was the only startup in the cycle with signif-
icant amounts of Xe, and the time elapsed between the trip and
startup involved estimating Xe on the peak Xe curve from the decay of
iodine following a reactor trip. Previous estimates of Xe had been a
source of debate and a measurement of Xe in this cycle had not been
performed.

. Review of the nuclear instrument chart recorder traces was performed
+
on June 6-7, 1985, at the request of the inspectors. That review
revealed that the startup rate on 5/17/85 at 0600 hours0.00694 days <br />0.167 hours <br />9.920635e-4 weeks <br />2.283e-4 months <br /> had been
faster than the 1.0 decade per minute (dpm) specified by the plant
procedures, specifically 0P/2/A/6100/01, Controlling Procedure for
Unit Startup (item 2.3), and OP/2/A/6100/05, Unit Fast Recovery (item
1..
2.1).- The licensee's evaluation of the rate was 1.3 dpm, and the
inspectors calculated 1.8 dpm. Failure to follow procedure was
identified as a violation of Technical Specification 6.8.1.a which
requires that written procedures shall be established, implemented,
and maintained for operating procedures, Violation 370/85-21-01,
Failure to follow procedures.
d. Restart on 5/17/85
For the restart at 1149 hours0.0133 days <br />0.319 hours <br />0.0019 weeks <br />4.371945e-4 months <br /> on 5/17/85, a new estimated critical
rod _ position was calculated using plant procedure Reactivity Balance
'
Calculation, Enclosure 5.2 of OP/0/A/6190/06. An estimated position
!- of 228 steps on bank D was calculated. This is all rods out. Step 9
4
of the procedure yielded a negative number for the reactivity worth
i of rods to be inserted and a negative value required an estimated
critical boron calculation per Enclosure 5.1. This would have
required a boron dilution but the results of the enclosure were
ignored and a procedure change not initiated to update the Xe values :
'
believed to be in error. The procedure had been checked by a second
licensed operator.
The dilution was ignored due to the fact that the engineer believed
i the Xe to be in error and a dilution would have resulted in a possi-
ble repeat of the criticality below the insertion limits. The Xe
< worth was thought to be 717 pcm less than as previously used. The
boron concentration also had been increased by 227 ppm.' Using these
l values the critical position was estimated by the engineer to be
around 100 steps on bank D. The actual critical position was 90
steps.on bank D. In effect, the procedure was used to estimate
critical rod position and was used as a test to determine Xe worth.
Failure to follow procedure was identified as a second example of the
violation of Technical Specification 6.8.1.a. which requires that
I, written procedures shall be established, implemented, and maintained
,
for operating procedures (370/85-21-01). This violation was dis-
,
cussed with plant management in the exit meetings on 5/24/85 and
- 6/7/85.
'
e. ~ Computer Changes after the Startup to Correct Xe Values
'
'
The value for Xe worth used in step 3 of OP/0/A/6190/06 comes from a
l
computer program. Changes were initiated to the plant off-line
computer which were not in accordance with nomal procedures.
i Nomally, the corporate nuclear engineering staff reviews these
changes and after approval the computer technicians make the changes,

On 5/17/85 the changes were made to the off-site (corporate) computer
first by computer technicians and then mailed to corporate for.
approval. Discussions with corporate personnel revealed that they
were initially unaware of the event and first learned of the event
days _later from another facility.
The on-line (process computer) was updated with new Xe values on
5/22/85. Changes to the plant computers are made with a Production
Technical Services Service Request Routing and Approval Form (Form
34744 (12-81)). This form requires approval by a technical sponsor.
The reviews of these forms in the past had not identified any errors
in Xe values.
Subsequent analysis of the process through which the Xenon Follow /
Predict program is changed revealed some concerns, which are detailed
below.
Changes to the Xenon Follow / Predict program were made without per-
forming a Nuclear Safety Evaluation of the change. There have been-
-at least five recent changes to this program, none of which had an
associated Nuclear Safety Evaluation until May 24, 1985.
1) June 29, 1984 (Initial cycle values)
2) July 9,1984 (Change to near vendor values)
3) Sept. 11, 1984 (Errorintroduced)
4) April 24, 1985 (Unit 2 cycle two initial values)
5) May 17, 1985 (Correction)
The evaluation for the May 24, 1985, change was performed five days
after the change had been implemented. In an effort to determine why
the evaluations had not been performed, it was detennined that the
licensee did not recognize that changes to the computer calculated
values were considered to be a procedure change. Administrative
Policy Manual 4.2.4.1.e requires all procedures changes to receive a
nuclear safety evaluation prior to use. Since the calculation
derived from the computer program are directly employed in procedure
OP/0/A/6190/06 Reactivity Balance Calculation for determining esti-
mated critical positions _and shutdown margins, which are safety-
related detenninations, the change should receive the same
considerations of technical viability and safety implications as any
other change to a safety-related procedure. Any change, therefore,
should be preceded by a Nuclear Safety Evaluation.
The. failure to implement Nuclear Safety Evaluations for changes to
the referenced computer program is a violation to the requirements of
10 CFR 50 Appendix B_ criterion V. Activities affecting quality are
required to be accomplished in accordance with instructions or
procedures appropriate to the circumstances which embody the neces-
sary acceptance criteria to ensure the satisfactory accomplishment of
the task. Data such as the Xe values used in the procedure are
required to be technically valid and receive the-same review and
. .

approval as the procedure in which it is employed. This is violation
50-369/85-20-01, 50-370/85-21-02, Failure to review procedure
changes.
f. Inspector Review of Shutdown Margin Calculations
The inspector reviewed the shutdown margin calculation performed on
5/17/85 prior to the 1149 hours0.0133 days <br />0.319 hours <br />0.0019 weeks <br />4.371945e-4 months <br /> startup on May 17, 1985, and found
that by using the inflated Xe values in the procedure, errors result-
ed in the nonconservative direction. The procedure, Shutdown Margin
- Unit Shutdown, Enclosure 5.5, allows taking credit for the Xe worth
in the shutdown margin and estimates a time that boration would be
required as the Xe decays. The time was determined to be 2100 hours0.0243 days <br />0.583 hours <br />0.00347 weeks <br />7.9905e-4 months <br />
using the inflated Xe values and 1700 hours0.0197 days <br />0.472 hours <br />0.00281 weeks <br />6.4685e-4 months <br /> using the Xe curve with
the updated Xe values.
The inspector requested a review of all past shutdown margin calcula-
tions performed since the introduction of the Xe error in Unit 1
cycle two. These records were not available. The licensee performed
the surveillance calculation but was retaining only the shutdown
margin value and not retaining the data used to perform the calcu-
lation. The inspector stated that this practice was inconsistent
with record retention requirements for surveillances required by
Technical Specifications. The records for the shutdown margin
surveillance, as required by T.S. 4.1.1.1.1.e, while in modes 3, 4
and 5 for the period August 1984 to June 1985 were unavailable. With
the reactor in mode 3, 4, or 5 the shutdown margin is required to be
determined once every 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> considering the following factors:
1) Reactor coolant system boron concentration
2) Control rod position
3) Reactor coolant system average temperature
4) Fuel burnup based on gross thermal energy generation
5) Xenon concentration
6) Samarium concentration
The Technical Specification requirement is implemented in Station
Directive 2.1.1 attachment 5, Document Retention Requirements, which
requires a six year retention of completed safety-related permanent
station procedures that involve documentation of compliance with
acceptance criteria. The failure to retain the records was identi-
fied as violation 50-369/85-20-02 and 50-370/85-21-03.
g. Licensee Reconstructed Data for Shutdown Margin
The licensee was able to reconstruct some of the data used for
determination of shutdown margin. A review of these data was per-
formed to determine if the required shutdown margin had been reduced.
This review was conducted using the updated Xe values and minimum
boron concentration following reactor trips or shutdowns from the

cycle two. A check was made to determine if the decay of Xe reduced
the shutdown margin. The licensee also stated that the shutdown
boron concentration curve contained a 100 ppm (1000 pcm) safety
factor.
The results of the review revealed that on 2/5/85 the reactor trip
was 23 ppm short of the required shutdown margin but, by using the
100 ppm safety factor, 77 ppm was available before the shutdown
margin was violated. Also, for the shutdown on 11/23/84 and cooldown
on 11/24/84 it could not be determined if the required boration took
place prior to or after cooldown due to the lack of records of boron
sampling times.
The results of the review were not made available for the inspectors
review until 6/6/85. The inspectors questioned the source and basis
of the 100 ppm safety factor. The safety factor is built into the
vendor supplied table for the shutdown boron concentration. Discus-
sion with the vendor revealed the safety factor is introduced because
of known uncertainties in the vendor calculations such as control rod
worths, and boron worth, and that the safety factor is not an addi-
tional margin available to the licensee. A vendor engineer offered
the opinion that approximately 25 ppmB excess margin was available
because measured boron concentrations at McGuire were consistently
less than the predictions of the Westinghouse calculations.
h. Review of Unit Trip on 6/1/85 and Startup on 6/2/85
The reactor trip of Unit 2 cycle two at 0919 hours0.0106 days <br />0.255 hours <br />0.00152 weeks <br />3.496795e-4 months <br /> on 6/1/85 and
startup on 6/2/85 was reviewed for estimated critical rod position
problems. At the time of startup, after the trip, the value of the
Xe worth was greater than 100% power equilibrium. The startup was
conducted using the corrected Xe values implemented after 5/17/85
(nearvendorvalues). The estimated critical rod position was within
500 pcm of the actual rod position and no problems were noted during
the startup.
i. Summary and Conclusions
The corporate nuclear engineering staff conducted an evaluation of
taking the reactor critical below the rod insertion limits and
identified two safety parameters of concern - the available shutdown
margin and the ejected rod worth. The shutdown margin for Unit 2 at
0600 hours0.00694 days <br />0.167 hours <br />9.920635e-4 weeks <br />2.283e-4 months <br /> on May 17, 1985 was found to exceed the required margin.
The ejected rod worth was within that analyzed in the Reload Safety
Evaluation.
The startup procedure should have been revised prior to the second
startup when it was found to be incorrect. Further, inadequate
reviews of reactivity parameters used in estimated critical rod
position and shutdown margin calculations led to the problem of
taking the reactor critical below the rod insertion

limits, exceeding the startup rate limit prescribed by procedure and
the possibility of nonconservative errors in the shutdown margin
-calculations. The lack of plant records of previous shutdown margin
calculations made the review process difficult. A complete review of
this event was not conducted by the licensee until prompted by the
-inspectors.
6. Post-Refueling Startup Tests Unit 2 Cycle Two (72700). 1
The following post-refueling startup tests for Unit 2, cycle two were
reviewed:
,
a. PT/0/A/4150/21, Post Refueling Controlling Procedure for Criticality,
Zero Power Physics, and Power Escalation Testing. The test was
approved on April 25, 1985 and performed on May 4-24, 1985. The
impact of core alterations on excore detector signal was evaluated
and found to be acceptable (step 8.3). The predicted shutdown margin
at the rod insertion limit was 3115 pcm, considerably in excess of
the minimum required of 1300 pcm (step 8.4). The shutdown margin for
the rod-swap tests (reference bank in) was acceptable (step 8.5).
More than one decade of overlap between the source-range and inter-
mediate-range nuclear instruments was demonstratea, enclosure 13.2.
Using enclosure 13.3 the point of adding nuclear heat and the upper
power limit for zero-power testing were established. Performance of
the reactivity computer was compared against stop-watch period and i
reactivity measurements for reactor instrumentation using enclosure
13.4, and found to be acceptable,
b. PT/0/A/4150/28, Criticality Following a Change in Core Nuclear
Characteristics. The test was approved April 24,-1985, and performed
on May 4-5, 1985. The chi-squared statistical test was used to
confirm proper operation of the source range detectors used in
providing input for the inverse multiplication calculations that
guided the approach to criticality.
c. PT/0/A/4150/10, All Rods Out Boron Endpoint Measurement, was approved
on April 26, 1984 and performed on May 5-8, 1985. The predicted
all-rods-out boron endpoint concentration was predicted to be 1491
+/- 50 ppmB. The measured result was 1423 ppmB, which was outside
the numerical acceptance limits. The result was evaluated by Westing-
- house, at the request of the licensee and found to be acceptable.
d. PT/0/A/4150/12A, Moderator Temperature Coefficient of Reactivity
,
during Startup Mode. The test was approved on April 26, 1984. It
was performed for all rods out on May 6, 1985 and with bank D in on
- May 7, 1985. Although the results were acceptable, the inspector
noted that the differences in results between heatup and cooldown
measurements were greater than observed in the past. The temperature
'
increments were only one degree F. Larger increments would yield
,
more consistent results, and would be compatible with the fuel
1 vendor's recommendations for startup tests,

e. PT/0/A/4150/11, Control Rod Worth Measurement, was approved on
April 26, 1984. It was performed on May 6, 1985, for control bank C,
which was to be used as the reference bank in later rod-swap measure-
ments. The reactivity computer traces were independently evaluated
by the inspector, and good agreement with licensee values (within 0.2
pcm per increment) was obtained. The measured worth was 871 pcm,
which was in acceptable agreement with the predicted value of 908 +/-
91 pcm.
f. PT/0/A/4150/11A, Control Rod Worth Measurement, Rod Swap, was ap-
proved on April 30, 1984, and was performed over the period May 6-7,
1985. All measured worths met the acceptance criterion of less than
30% or less than 200 pcm difference from prediction.
g. PT/0/A/4150/02A, Core Power Distribution, was approved on April 19,
1985. The first measured power distribution at.100% power was,
performed on May 15-18, 1985. All thermal and power distribution
limits were satisfied.
h. PT/0/A/4600/02E, Incore and NIS Recalibration: Post Outage, was
approved on May 25, 1984, and performed on May 10-12, 1985. The
results of eleven quarter-core flux maps were analyzed using a
computer program to obtain the correlation between the individual
chamber currents of the power range detectors and axial offset. The
program does not perform an evaluation of the quality of fit of the
data to the correlation line. The licensee stated that the results
are also plotted by hand and a visual evaluation of the reasonable-
ness of the results performed. The inspector had no further ques-
tions regarding this practice.
