EXECUTIVE SUMMARY

Byron Generating Station, Unitt 1 and 2

NRC Inspection Report No. 50-454/g7024(DRP), 50 455/g7024(DRP)

This inspection included aspects ..isee operations, maintenance, engineering, and plant

support. The report covers a six w. k period of resident inspection.

Operations

  • Routine control room operations were conducted safely and conservatively Good

annunciator alarm response was observed and the operators were knowledgeable of the

states of all the annunciator alarras. Operators were aware of activities that could affect

the safe operation of each unit. Good communication between the unit operators and

good supervisory oversight by the unit supervisors were also noted (Section 01.1). .

+ The housekeeping for Unit 2 was very good. Unit 2 structures, systems, and components

were easily accessible to operators. General area housekeeping was good given the

amount of outage activities that were in progress during the inspection period.

Equipment was staged app,opriately and carts property secured. The control of outage

related material was good except for two failures to control transient combustible material

(Section 01.1).

  • The shutdown risk program and its implementation were excellent, A detailed licensee

- _

review of the outage schedule was conducted. The licensee deiermined the risk level for.

each key safety function based on plant configuration and equipment Lvailability and used

safety system functional assessment trees (SSFATs). A core damage frequency (CDF)

was included in the risk profile. The shutdown nsk review board (SRRB) approved all

changes to the shutdown risk models. Shutdown risk was communicated to all station

personnel. Contingency plans provided additional guidance for operators and existed for

most higher risk conditions (Section 08.1).

  • The Plan of the Day (POD) meeting was an effective communication tool and helped

identify key performance measures at the site (Section 08.2).

Maintenance / Surveillance

  • Observed maintenance and surveillance activities were conducted well. Maintenance

procedures were used and personnel were knowledgeable of the associated activities.

Surveillance testing was performed well with prope* authorizations, good procedure

adherence, and effective communications and coc.anation (Section M1.1 and M1.2).

  • Based on procedure usage, supervisory oversight, and adequate protection of Unit 2

systems, the observed Unit i steam generator removal and replacement activities were

conducted appropriately (Section M1.3).

engineering staff were actively l'.. olved it the oversight of contractor personnel and were

knowledgeable of the evolutions il ey obs irved (Section E1.1).

  • A process for the identification, traceung, and resolution of nonconformances for the

SGRP was successfully implemented and appeared to be effective. A potential

weakness existed in that operations personnel were not involved in the nonconformance

repori review process (Section E7.1).

Plant Support

moving radiological area existed. The radiologleal protection (RP) technicians controlled

both the number of personnel near the old SG and the distance between nonessential

personnel and the old SG. Radiation Protection Supervision also ensured that the

transport evolution was properly controlled (Section R1.1).

.

The inspectors concluded that the methods for controlling the use of a drinking water

station in a high radiation / contaminated area on December 24,1997, created a potential

problem. Although there had not been any known contamination events attributable to

the manner in which the drinking water station was controlled, an individual could

potentially be contaminated due to the lack of direct control by RP technicians, the

general access to the water station, and the lack of personal surveys.

  • The security force properly controlled the fence penetration during the transport of an old

SG on December 17,1997. Good access control of personnelleaving and retuming to

the protected area through the fence penetration existed. Security supervisicn was

present. The protected area penetration was well controlled (Section Si.1).

  • The increased amount of transient combustibles during the refueling outage was not

always aggressively controlled. Two instances of poorly controlled combustibles were

identified. A 55-gallon barrel containing oil soaked rags and 13 containers of a flammable

liquid were both identified by the inspectors. Two violations of a failure to follow Byron

Administrative Procedure (BAP) 1100-9, " Control, Use, and Storage of Flammable and

Combustible Liquids and Aerosols," were cited (Section F1.1).

Romort Details

Summary of Plant Status

Unit i remained shutdown for a steam generator replacement outage for the duration of the

inspection period. During the pedod, all four old steam generators were removed, and all

replacement steam generators were set in place. Welding the new steam generators in pison

continued at the 6nd of the inspection period, and the containment hole was being restored.

Unit 2 operated at or near full power for the entire inspection period.

l. Deerations

01 Conduct of Operations

01.1 General Comments (71707)

During the inspection period, the inspectors conducted several observations of control

room activities.- The inspectors routinely observed good annunciator alarm response and

the operators were knowledgeable of the status of all the annunciator alarms. Operators

were aware of activities that could affect the safe operation of each unit. The inspectors

also observed good communication between the unit opemtors and good supervisory

oversight by the unit supervisors. The inspectors concluded that routine control room

. operations were conducted safely and conservatively.

The inspectors also made routine inspections of the auxiliary and fuel handling buildings -

during the inspection period. Due to the steam generator replacement outage in progress

on Unit 1, the inspectors focused on Unit 1 activities that potentially affected Unit 2. The

inspectors considered the housekeeping for Unit 2 very good. Unit 2 structures, s, . ems,

and components were easily accessible to operators. General area housekeeping was

good given the amount of outage activities that were in progress during the inspection

period. The inspectors routinely observed equipment staged appropriately and carts

= properly secured. The inspectors considered the control of outage related material good

except for two specific failures to control transient combustible material, discussed in

Section F1.1.

04' Miscellaneous Operations issues (71707)

08.1 Shutdown Risk Proaram

a. Inspection Scope

'

During the inspection eriod, the inspectors reviewed the licensee's shut down risk

program. The review ncluded discussions with the shutdown risk coordinator, a review

of BAP 1750-6, " Shutdown Risk Program Summary," Revision 3, and a review of the

licensee's shutdown risk manual for refueling outage B1R08. The inspectors also

routinely observed shutdown risk postings and discussions of shutdown risk at daily briefs

and meetings.

b. Observations and Findinat

The licens .e's shutdown risk program provided control of components and systems

important to safety during unit outages. The control was provided through heightened

awareness of plant status during oute, ss, a committee review process for the scheduling

of risk significant activities during an outage, and contingency plans for risk significant

activities.

The inspectors routinely observed a heightened awareness of plant risk status during

outages. The licensee used posters, daily outage summaries, closed circuit television,

and discussions during both the operating crew brief and plan of the day meeting to

emphasize the shutdown risk associated with Unit i activities. The inspectors found that

station personnel awareness of the shutdown risk status wab excellent.

The licensee used a computer p*ogram colled Outage Risk Assessment Models (ORAM)

to assist in the review of risk significant activities. The shutdown risk coordinator

reviewed the outage schedule, identified risk significant activities, and then used the risk

significant outage schedule for the outage risk profile development. Both deterministic

and probabilistic approaches were included in ORAM. The deterministic portion allowed

the shutdown risk coordinator to include a defense in depth concept, Technical

Specification (TS) requirements, Updated Final Safety Analysis Report (UFSAR)

information and engineering judgement when safety system functional assessment trees

(SSFATs) were created. The licensee determined the risk level for each of seven key

safety functions based on plant configuration and equipment availability and risk level was

identified by color coding. Since the original outage risk profile was developed from a

schedule, the actual status of equipment was compared twice dally to the expected

equipment status and any discrepancies resolved. A probabilistic approach was also

included. The core damage frequency (CDF) profile was created for the outage and

included as an indicator of risk.

The licensee used a Shutdown Risk Review Board (SRRB) to review and approve all

changes to the shutdown risk models. The SRRB also reviewed and approved risk

profiles before the licensee began an equipment outage. The SRRB consisted of the

shutdown risk coordinator (either a licensed operator or a person having completed

license certification), at least one currently licensed operator, an outage management

representative, and a qualified nuclear engineer for reactivity issues. Senior station

management conducted a final review and approval of the outage risk profile,

Contingency plans were developed to mitigate challenges to key safety functions. A

cuntingency plan was required for higher risk activities. The plans were written to use

. Installed or temporary equipment and procedures. Typically contingency plans also

included increased monitoring of affected equipment.

c. Conclusions

The inspectors concluded that the licensee's shutdown risk program and its

implementation were excellent. A detailed review of the outage schedule was conducted.

The licensee determined the risk level for each key safety function bas 3d on plant

y configuration and equipment availability using SSFATs. A CDF was included in the risk

profile. The SRRB approved all changes to the risk models. Shutdown risk was

08.2 1Q,pFR 50,54ff) Letter Commitment Review

e. Inspection Scope

The inspectors reviewed the status of selected commitments pertaining to the

licensee's March 28,1997, response to the NRC's request for information pursuant to

10 CFR 50.54(f). The commitment numbers correspond to those used by the licensee in

their response,

b. Observations and Find: 31

Commitment 266: "The Plan of the Day meeting is being restructured to communicate

and discuss key performance measuras and current issues at the site."

The inspectors periodically attended the Plan of the Day (POD) meeting. The POD was

structured to communicate recent events, present plant status, and discuss planned

work. Each day a presentation was made by different department representatives,

discussing current issues, typically including performance measures.

c. ponclusions

The inspectors concluded that the POD was an effective communication tool and helped

identify performance measures at the site,

M1.2 Surveillance Observations (61726)

a. Inspection ScoAt

The inspectors observed the performance of all or parts of the following surveillance

tests. The inspectors also reviewed plant equipment and surveillame testing activities

against the UFSAR descriptions.

b. Qbservations and Findinos

The inspectors noted that proper authorization was routinely obtained from the control

room senior reactor operator (SRO) before the start of each surveillance test. At the

completion of the surveillance test and after independent verification of system

restoration, the TS action requirement was cleared. The inspectors observed the

communications between operators in the control room and the auxiliary building, and

observed the coordination between the nuclear station operators and nonlicensed

operato+s Test instruments used were verified to be calibrated as applicable. The

inspectors reviewed completed surveillance tests and verified the surveillance tests met

the acceptance criteria.

ASME Surveillance Reauirements for the 2B Residual Heat Removal (RH) Pumo

The inspectors observed the second attempt by the licensee to perform an ASME

surveillance on the 2B RH pump. Due to over ranging the suction ressure gauge, the

first attempt to perform the surveillance had been unsuccessful. The surveillance test

required the suction gauge to read within 80 percent of full scale. During the first attempt,

the gauge read greater then 80 percent of full scale cue to RH system check valve

leakage (discussed in inspection Report No. 50-454/97022; 50-455/97022, Section M2.1).

The licensee performed a temporary procedure change and installed an additional suction

pressure test gauge. The test was repeated and test data gathered with no further

problems identified.

c. Cor.clusions

The inspectors concluded that, based on proper authortzation, good procedure

adherence, effective communication and coordination, and proper verification that the

surveillance test acceptance cdteria were met, the observed surveillance testing was

performed well.

M1.3 Steam Generator Replacement Frolect (50001)

a. Inspection Scope

Steam generator removal and replacement activity observations were conducted in the

Unit 1 containment and spent fuel pool area. The inspector observed the general

activities and the following specific work activities:

  • A40232MM Containment / Equipment Hatch Removal for the Transfer of

Equipment into the Containment.

  • B(A/D/B/C)SG0100 Holst SG Out of the Containment and Replace with New SGs.

b. Observations and Findinos

The inspectors observed construction activities during the SG replacement outage. The

inspectors observed procedures in use during work activities. The new SGs were stored

according to the manufacturers recommendations to prevent degradation during storage.

The installation of temporary services (welding equipment, power supplies, and lighting)

was completed as described in the procedures. The inspectors also frequently observed

supervisors observing the work activity.

Work activities did not affect the operability of common systems required to support

Unit 2 full power operation. During SG removal and replacement activities, the inspectors

verified that safety related equipment and systems required to be operable per TS and

the UFSAR wers not impaired by the activities,

c. Conclusion

Based on procedure usage, supervisory oversight, and adequate protection of Unit 2

systems, the inspectors concluded that the observed Unit i SG removal and replacement

activities were completed appropriately.

transport of an old SG. The inspectors conducted interviews with the SGRP site project

manager, the SG construction lead engineer, and the SGRP lead mechanical engineer.

The inspectors also accompanied the SGRP lead civil engineer and civil engineering staff

on field inspections.

b. Observations and Findinas

From December 17 through ig,1997, inspectors performed an assessment of licensee

oversight of contractors involved in the SGRP The inspectors were told by the SG

construction lead engir,eer that field engineers physically monitored all major evolutions

associated with the SGRP. The field engineers typically verified that the contractors

followed the approved work packages, that acceptance criteria were met, and that quality

control requirements were satisfied. The SGRP lead engineers for each discipline (civil,

electrical, and mechanical) were also involved with problem resolution.

The inspectors accompanied the SGRP lead civil engineer and civil engineering staff on

field inspections. The inspectors observed the horizonta, otation of a new SG, the

lowering of two of the old SGs, the operation of the outside lift system, and the transport

of an old SG During the rotation of the new SG, the inspectors observed the SGRP lead

civil engineer review the work package. The engineer also verified that the work package ,

documentation reflected the physical condition of the SG, verified quality control

requirements had been completed, and discussed the status of the job with the

responsible foreman.

The inspectors accompanied the SGRP lead civil engineer and civil engineering staff as

they observed the lowering of the two old SGs. The lowering of each SG from the runway

to the transport vehicle by the outside lift system was performed without problems. Prior

to the transport of each SG to the old SG storage facility, the SGRP lead civil engineer

verified that all prerequisites were completed. The transport of the SGs to the old SG

storage facility also was performed without any problems,

c. Conclujlons

The Inspectors concluded that the licensee's oversight of contractors during the

hotontal rotation of a new SG, the lowering of two old SGs, the operation of the outside

lift system, and the transport of an old SG was effective. The SGRP lead civil engineer

and civil engineering staff were actively involved in the oversight of contractor personnel

and were knowledg6able of the evolutions.

b. Observations and Findinas

The inspectors discussed the Pacess for identifying, tracking, and resolving

nonconformances with the SG construction lead enginear and the SGRP lead mechanical

engineer. The inspectors were tesid that identification and the disposition of

nonconformances were accomplished by a nonconformance report (NCR). The NCR was

'

reviewed by the contractor's quality control personnel and project ugineering personnel

with copies of the NCR pmvided to Comed SGRP site quality verification (SQV) and

Comed SGRP engineering groups. The licensee's problem identification forms (PIFs)

were not used unless the nonconformance was outside the scope of the contiactor's

work.

c. Conclusions

The inspectcis concluded that a process for the identification, tracking, and resolution of

nonconformances for the SGRP was successfully implemented and appeared to be

effective. A potential weakness existed in that operations personnel were not involved in

the nonconformance report review process.

IV. Plant Support

R1 Radiological Protection and Chemistry (RP&C) Controls

R1.1 Radiolooical Control of Old SG Durina Tra7 sport (71750. 50001)

The inspectors observed the removal of an old SG from the Unit 1 containment on

December 17,1997. While the old SGs were lowered to the ground and during transport

to the old SG storage faciiity, a moving radiological are : existed. The licensee ensured

the entire SG was encapsulated with an extra coating to prevent any possible spread of

con * amination. The radiological protection (RP) technicians also controlled both the

number of personnel near the old SG and the distance between nonessential personnel

and the old SG. Active participation by RP supervision was also noted by the inspectors.

The inspectors concluded that the transport evolution was properly controlled.

R1 ? Control of Drinkina Water inside a Radioloaically Posted Area (71750. 50001)

a. Inspection Scope

On December 24,1997, during a routine inspection of th3 auxiliary and fuel handling

buildings, the inspectors noted a 5-galloq water fountain inside the radiologically

posted area (RPA). The inspectors reviewed Byron Radiation Protection Procedure

(BRP) 5000-7," Unescorted Access to and Conduc,t in Radiologically Posted Areas,"

Revision 7, and Station Policy 12, " Drinking Water in the RPA," Revision 2.

10

..

.

- b. Observations and Findinas

~ The inspectors observed that the drinking fountain was placed such that a person coming

out of the Unit 1 containment could obtain a drink of water while still in an area posted as

a high radiation area (HRA) and corataminated area. A hole was cut in the plexiglass

boundary of the HRA, and the water bottle was located in the RPA such that the spigot

penetrated into the HRA and contaminated area. A procedure was posted on the bottle

indicatir:g that to get a drink, a worker should remove an outer glove, take a paper cup,

get a drink, and then crush the cup and place it in a potentially clean trash barrel. No

personnel were in the HRA, and the inspectors did not identify any RP personnel in the

immediate area of the water bottle.

The inspectors discussed the availability of drinking water in the RPA with the Radiation

Protection Manager (RPM). The RPM stated that the purpose of having water s.vailable i

was to prevent heat stress and that the water was controlled by RP personnel as stated

in the station policy. On December 24,1997, the inspectors noted that the water station

was not directly controlled. The inspectors also noted that no method to perform a hand

contamination survey, cr frisk, before using the drinking water station existed; however,

RP personnel routinely surveyed the area for contamination, and no personnel

contamination events occurred related to drinking the water.

Following the inspectors' observations, the licensee stated the controls for the use of the

drinking water facility were improved. Changes included posting the water bottle for heat

stress relief use only and requiring that RP personnel only dispense the water. The -

licensee also moved the water bottle such that it was under direct RP personnel control.

The inspectors considered the improvements appropriate.

c. Conclusions

The inspectors concluded that the methods for controlling the use of a drinking water

- station in a high radiation /cor,taminated area on December 24,1997, created a potential

problem.' Althoug5 there had not been any known contamination events attributable to

the manner in which the drinking water stations was controlled, an !ndividual could

potentially be contaminated due to the lack of direct control by RP technicians, the

general access to the water station, and the lack of personal surveys.

-81 Conduct of Security and Safeguards Activities (71750,50001)

S1.1 Removal of Old SG from Protected Area -.

The inspectors observed the removal of an old steam generator from the protected area

on December 17,1997.- The inspectors observed the security control of the fence

penetration and access control of personnelleaving and retuming to the protected area

through the fence penetration. Security supervision was present. The inspectors

considered the penetration well controlled.

F1 Control of Fire Protection Activities (71750)

F1.1 Transient Comtstible Material Control

a. Inspection Scope

Curing routine inspections of the auxiliary building, the inspectors observed the licensee's

control of comt ustible material. The inspectors also reviewed BAP 1100-9, " Control,

Use, and Storage of Flammable and Combustible Liquids and Aerosals," Revision 4.

b. Observations and Findinas

On December 3,1997, the inspectors observed mechanical maintenance personnel

performing planned maintenance on the 1 A chemical and volume control (CV) pump.

The inspectors noted a 55-gallon barrellocated outside the CV pump room that contained

oil soaked rags. The inspectors also observed the mechanics working on the 1 A CV

pump using the SS-gallon barrel as storage for oil soaked rags.

During the review of BAP 1100-9, the inspectors noted that paragraph C.6.c stated that

flammable / combustible liquid soaked rags , , . shall be disposed of by using an approved

waste can with a self closing lid. The inspectors identified the discrepancy to the Fire

Marshall and the SS-gallon barrel was removed and replaced with an appropriate

self closing lid container. The Fire Marshall also stated that the 55 gallon barrelwas not

an approved container. The inspectors concluded that the use of a 55-gallon barrel to

store oil soaked rags was a failure to follow BAP 1100-9 and a violation of TS 6.8.1 as

described in that attached Notice of Violation (50-454/455-97024-01(DRP)).

On December 8,1997, the inspectors identified 13 containers of Carboline staged near

the Unit 2 fuel transfor canal control panel. The inspectors noted that the buckets were

labeled as flammable.- The inspectors did not notice a Transient Fire Load tag and

confirmed that a Transient Fire Load Permit had not been issued. After the inspectors

identified the discrepancy to the operating crew, a Transient Fire Load Permit was

prepared.

Byron Administrative Procedure 1100-9, paragraph C.2.a stated that all flammab!s and

combustible liquid containers transported into plant areas which will be left unattended

shall have prior authorization by the Station Fire Marshal / designee. Authorization shall be

accomplished by completing a Transient Fire Load Permit and submitting it to the Station

Fire Marshal / designee for approval. An approved Transient Fire Load tag will then be

issued upon Fire Marshal approval. The inspectors concluded that the failure to obtain a

Transient Fire Load Permit was a failu'e tv, follow BAP 1100-9 and a violation of TS 6.8.1

(50-454/455-97024-02(DRP)).

c. Conclusions

The inspectors concluded that the licensee did not always aggressively control the

increased amount of transient combustibles during the refueling outage. Two

independent cases of poorly controlled combustibles were iden'ified by the inspectors

during the inspection period. On separate occasions, a 55-galk, i barrel of oil soaked
