FOLLOW-UP ON OPEN ITEMS
(Open) 85-26-03, Review the responsibility to make PARS in the Emergency
Plan and procedures. Section 6 of the Emergency Plan was reviewed and
noted to have been changed to clarify the licensee's responsibility to
formulate and make a protective action recommendation (PAR) to offsite
authorities when conditions warrant. The emergency procedures were
reviewed and noted to contain provisions for protective action
recommendations.- However, the notification form used to notify the
offsite authorities referenced AP 528 (Protective Action Guides) which
'
provided no guidance on PARS associated with detericrating plant
conditions, rather it offered guidance only for PARS based upon the
results of dose projection. The procedure was determined to be
inadequate to be used as a tool for the formulation of PARS based upon
plant conditions. This matter is discussed further in paragraph 4B.
(Closed) IN 85-44, Monthly testing of the ENS _and HPN. The licensee had
reviewed this Information Notice and their procedures for the. monthly
checks and changed them to include a check of the Emergency Notification
System from the Control Room and the TSC.
Records of monthly checks
were reviewed for 1985 and noted to be adequate.

Center. The-licensee has followed the guidance in this notice and placed
backup numbers for the NRC Operations Center on the ENS phones in the
Control Room (CR), Technical Support Center ( TSC), and the Emergency
I
Operations Facility (EOF). A physical inspection of the ENS phones inL
l
the CR and TSC demonstrated that the labels had'been placed on the phones
I
and the correct numbers were in place.

i
. (Closed) IN-85-77. Possible Loss of ENS Due to Loss of AC Power.
1
According to the licensee's file on this issue, the information notice'
i
had been reviewed and an evaluation of the wiring for the ENS system was
~
made. .The licensee determined that the system was adequately wired and
would remain operable if there was a loss of AC power.

KNOWLEDGE AND PERFORMANCE'0F DUTIES (TRAINING)
t
The Emergency Plan, emergency implementing procedures,and records of
'
4
training were reviewed and interviews with plant personnel, Emergency.
j
Planning Personnel and the Training Manager were held. The following are
-
!
the findings and observations.
A review of the licensee's emergency preparedness training program
revealed the-licensee's contracted training program and related training
i
procedure (Temporary Change AP 580) for emergency preparedness training,-
had expired on 12-31-85 and had,not been replaced by the beginning of
.
i
this inspection. When.the-temporary procedure was allowed to expire
!
without being replaced by another procedure', an outdated 1983 procedure,
which was not being implemented, became effective. The. licensee
.
currently plans to use the site training organization to accomplish.EP
'
training. On April 14, 1986,
ie licensee acquired'an additional
individual to help reestablish he emergency preparedness training
i
program, and to update AP 580 (Training).
i
'
The EP, Section 8.1.3.(a), states in part, "It is.the responsibility of
the Emergency Preparedness Coordinator to' assure appropriate personnel
receive Emergency Preparedness' Training."' In addition Section 8.1.3(c)
also states " Records of the District's Onsite Emergency Response
'
l
Organization training will be maintained by the Emergency Preparedness
Coordinator (EPC) with a copy to be forwarded to the Nuclear Training
Superintendent." The intent of Section 8 was to insure'that someone.in
'
the emergency organization was tracking EP training to assure personnel
1'
maintained their required training. The review of training. performed.
indicated the EPC was'not maintaining training records or tracking
required training. ~The EPC was in possession of a box of records from
<
the former contracted training organization. However, the EPC.wa's unable
,
to produce selected records of the onsite organization, which included
Control Room staff, and'did not. appear to have'a method to track required
,
'
training. The discussions revealed the EPC was not cognizant of the
status of EP training implementation.
.In~ addition, the licensee did not
appear to be maintaining a tracking' system to assure appropriate
,
individuals receive timely training. The licensee committed to the NRC in
'
a letter dated August'31, 1984, to establish a tracking system to assure
that training is maintained.' This review determined that the licensee
had initiated a Nuclear Tracking list, but failed to maintain it,'in that

the: list did not include all members of the' control room staff and those
individuals who would be designated for the Emergency Team. There was no
.
indication that the licensee was attempting to use the list for-its
intended purpose.
In order to ascertain the status of eme'rgency preparedness training, the
inspector examined individual training records maintained by.the Site
Training Department. The examination revealed that eight individuals-on
the Control Room staff had not received their annual. emergency
preparedness. retraining during periods that varied between 15.7.and'17
months. _Four of these individuals were Shift Supervisors, the
individuals who would be the Emergency Coordicator at the beginning of an
,
emergency. In addition 24 members of the District's Emergency Response
Organization, according to records, did not receive retraining including
,
personnel who would fill positions of the EOF Manager, Radiation
Assessment Coordinator, Technical Support Coordinator and'other essential
,
positions. Training for the above individuals varied between 16 and 20
months. AP 580, " Training" states th'at, " Training will be conducted
.
annually, and whenever necessitated by significant~ revisions to'the
Emergency Plan, Emergency Plan Procedures, equipment or when changes
occur to emergency assignments" and further references attachment.7.1'to
describe the specific training. Failure to conduct the required training
is an apparent violation of Technical Specification'6.8.1.e which-
requires implementation of procedures governing the EP.
In addition to the finding: 'dentified above, the matter of first1 aid
training was noted to be deficient. First aid training is described in
Section 6 of the Emergency Plan ~. Section'6.2.7 states " Health Physics
personnel and the Emergency Team are provided Advanced First Aid,
Standard Multi-Media and Cardio-Pulminary Resuscitation.(CPR) Training at
Ra'ncho Seco."
Section 6.2.7(d)(1) states, " Retraining of personnel
qualified in Advanced First Aid or Standard Multi-Media is conducted
every three years," and paragraph'3 states "At least one member of;the
Emergency Team will have Advanced First Aid training."
Based upon discussions with the site nurse.it' appears-that.the training
for advanced first aid was discontinued approximately 5 years ago, and
that multi-media first: aid was discontinued 3-years ago. Failure-to
conduct the required training'is an apparent violation of 50.54(q), that
requires the' licensee to follow and maintain in effect Emergency Plans
which meet the standards in 50.47(b).and the requirements of' Appendix E.
-The inspector further noted there'were no records to support that the-
licensee had conducted training that would_have been necessitated by.
changes in the Emergency Preparedness Program. . Discussions with licensee
personnel further supported that' training has not been provided in'
all cases. Examples of changes in the emergency preparedness program and
the subsequent lack of training are described in Paragraph 4 and 5 of.
this report,
f
Two apparent violations for failure to-implement training pursuant to 10 CFR 50.54(q)~and. Technical Spec,1fication 6.8.1.e-were identified. :The.
,
Technical Specification violation is a repeat violation.- A similar
violation ~was~ issued August.2, 1984. Apparently the licensee's
1
'
corrective actions contained in their, August 31,;1984 reply to the;
Notice of. Violation have been ineffective _(86-14-01).

CHANGES TO THE EMERGENCY PREPAREDNESS PROGRAM
h
Records of changes to the EP and implementing procedures were reviewed,
interviews with licensee personnel were performed, and changes in the
i
i
licensee's Emergency Response Organization.(ERO).were examined to
determine that the EP and implementing procedures are being adequately
maintained, and changes to the Plan and procedures do not degrade the
effectiveness;of.the.EP. As a result of.this review the inspector
identified a number'of instances where the EP and implementing procedures
were not maintained current. The following are the inspector's findings:
,
!
j-
a)
Prior to July:1955 The Herald Fire Department and,Ione Fire Academy
!.
were designated as offsite. relocation points'and provisions were
made to store emergency equipment and supplies at these facilities.
4
During July 1985 the licensee elected to remove emergency. equipment
s
from these 2 facilities, although they:still remain offsite
,
relocation points.> AP 519, " Site' Evacuation" was revised to reflect
i
the changes made to the Herald and Ione facilities. The revised-
procedure states in 5.2.2, " Radiation monitoring and decontamination
,
equipment must be brought from. Rancho Seco to the offsite relocation
i
point." The following procedures were not maintained in that
i
emergency equipment and'aupplies are still listed as available at
j
these facilities..
1)
Section 7 of the EP'still'11sts the Herald Fire Department &
j
- Ione Fire Academy as a place where-dedicated emergency
!
equipment and' supplies are stored. Emergency' lockers -
]
ambulance kits, and decontamination-(decon) kits are
_
j
specifically mentioned.
.
1
~
t
2)
AP 516, " Personnel Decontamination," Section 4 refers to
>
l-
decontamination kits which are maintained at the Herald Fire
'
Station and the Ion Fire Academy.
3)
AP 552, "Activ'ation And O Nration Of The Offsite Relocation
,
!
Points',". Sections 1 and 5 also reference emergency equipment,
protective clothing, curvey instruments, decontamination kits
'
and respiratory equipment, etc.
j
4)~
AP.305-9D,'" Personnel Decontamination," Sec' tion 3, still lists
Herald & Ione'as,an area where decontamination kits are stored.
,
~
~
It should be noted'that during a walkthrough'with an individual who
,
,
. would fill the position of the Radiation Assessment Coordinator the'
'
individual was not aware of the removal of the emergency equipment
formerly stored at the offsite relocation areas. The individual-
~
- ! .
also stated he had not' received'energency plan training in over a
-
~
year...The matter of training necessitated by changes to the
,
i
Emergency Preparedness Program was previously discussed in.ParagraphL

AP 528, " Protective Action Guides" Revision 1,. dated 9/27/85, added
a requirement'that Plant conditions or trends will be considered
when promulgating. protective actions to recommend to offsite
authoritiesa A review of this procedure identified that the
4
1
.
procedure only' addressed protective actions based upon dose
projection. - The ' statement " plant' conditions and trends" was merely
added.to the instruction portion of the procedure and not the body
l
of the. procedure. -The procedure and attachments do not offer-
~
'
~ guidance as to what plant condition or trend must be present to
recommend shelter or evacustion.
.

.
ic)
Th'e -EP, Section 7.1.2, Technical Support Center, states, "The
l
Technical Support Center (TSC) is located adjacent to the Control
.
i
Room and incorporates the Nuclear Operating Superintendents' office
j
area and the computer-room as shown'in figures 7.2 and 7.3.
This
'
procedure and attachments 7.2 and 7.3 have not been maintained
'
current, in that prior to' September 10', 1985 th'e licensee
'
,
'
established a new TSC separate from the Control Room. .The new
JL
facility is located down the hallway from the Control Room.
Section 7.1.5 of the Emergency Plan describes the First Aid Room as
,
- being adjacent to the Auxiliary Building and next to the Safety
Office. In addition Figure 7.8 shows this location as being in.the
building housing-the Tool-Room. The_First_ Aid Room was moved in the
fall of-1984. The new location of the First Aid room is in the T&R
,
Building next to the cafeteria.
Additional examples of noncurrent procedures are discussed in Section 5
of this report.
'
l
Based upon the~ findings of this inspection, the licensee has not
implemented an effective method to assure,that when changes to the.EP,
j
emergency implementing procedures, or emergency facilities occur, other
,
impacted procedures are identified and training is accomplished .for those;
i
j
individuals who may be affected by the changes.-
.
. 3
i
'
The. failure to. maintain the Emergency Plan ~and implementing procedures

Protective Action Guides, AP 528
Dose Assessment Codes (Racode, Jade, and Specter)
Interviews with key personnel responsible for dose assessment in the
Control Room (CR), Technical Support Center (TSC) and the Unified Dose
Assessment Center (UDAC) were held. The interviews with plant and
contractor personnel and procedural reviews identified several problems
as discussed below.
Radiation monitors R150044 and R150045 are the high range effluent
monitors for the reactor and auxiliary building vents. These monitors
were installed pursuant to item II.F.1 of NUREG 0737 and provide the
capability to measure gaseous effluents that might be expected during an
accident. The licensee's procedures that utilize source term for dose
,
~
assessment are contained in AP 509, " Control Room Dose Calculation," AP
511. "TSC Dose Calculation," and AP 512,." EOF Dose Assessment". None of
these procedures contain reference to nor incorporate any methodology to
convert high range instrument response to a source term. The importance
of being able to utilize data from the high range. effluent monitors is
partially illustrated by a careful review of AP-509, " Control Room Dose
Calculation". This procedure addresses release pathways from the
auxiliary building stack. If a calculation is performed using the
maximum reading from the normal range monitors (R15001 and R15002) and
default values (most conservative) for vent flow rate and X/Q, the
projected doses obtained are below the lowest range of Protective Action
Guide values listed in AP 528. Consequently, the procedure as written is
of limited value in assessing the dose consequences from a severe event
with a release rate greater than the capabilities of the normal range
monitors. From a previous NRC inspection (Report No. 50-312/86-06), it
is noted that AP-501, " Recognition and Classification of Emergencies"
also makes no reference to the high range monitors for purposes of
classifying an event. The failure to update and incorporate instructions
for use of the high' range effluent monitors (R150044 and R150045) in
procedures AP 501, AP 509, AP 511 and AP 512 represents an apparent
violation of Technical Specification 6.8.1.e which requires that written
procedures covering the emergency plan to be maintained.
J
Additional deficiencies were noted in procedures AP 509, 511 and 512 and
are discussed below,
a)
procedures AP 509 and 511 only provide a methodology for determining
the release rate from the auxiliary building. No methodology is
provided for the containment (reactor building) vent.
,
b)
procedure AP 512 states, "obtain the release rate from Attachment
7.1."
Attachment 7.1 has a place for recording release rates (noble
gas and iodine) but provides no methodology _on determining what the
release rate is from instrumentation readings.
Paragraphs (a) & (b) above are additional examples of failure to maintain
procedures.
Interviews with licensee personnel established that computer based dose
assessment is the principal method expected to be used by the licensee in
-
.

d
the TSC and EOF. Manual calculations would be performed by control room
personnel early in an event and as backup methodology for TSC and EOF
calculations. As discussed above, AP 511 and AP 512, "TSC Dose
Calculation" and " EOF Dose Calculation", respectively, are the licensee's
procedures governing dose. calculations. It is noted that in both of
these procedures the primary emphasis is on manual calculational
techniques. AP 511, under paragraph 5.0, " Instructions" has a note which
states, " NOTE: These calculations may be performed.using Apple II Code
"RAC0DE".
No further instructions are given.regarding how to use the
>
code, a description of the code, or its limitations and capabilities. AP
512 has a similar note that states." NOTE: These calculations may be
performed using Apple.II Code "UDACODE".
(See AP 554', Attachment 7.7)"..
,
The inspector noted that " JADE" has replaced "UDACODE" and Attachment 7.6
l
is the correct reference in AP 554. Otherwise the referenced
i
instructions (Attachment 7.6) appeared adequate for setting up and;
i
running the code. However, as is the situation with "RAC0DE", no further
instructions on code description, limitations and capabilities were
,
provided. Failure of AP 511 to provide instructions on use of computer
based dose calculations represents an apparent violation of Technical Specification 6.8.1.e for failure to maintain a procedure.
Further examination of the: licensees use of computer codes for dose
assessment. disclosed the following.
The licensee has three separate codes available for use in the TSC,
" JADE", " SPECTER" and "RACODE".~
t
Various changes to the codes occurred in 1985.
t
l
The Unified Dose Assessment Center'in the EOF only uses the " JADE"
!
code.
Only the " SPECTER" code provides a capabil'ity to calculate doses
i
j
based on a primary to secondary release source tera.. It is-also
noted that none of the licensees procedures for manual dose
calculation (AP 509, 511 and 512) contain methodology for
,
i
calculating doses from a primary'to secondary source term. Since
i
control room personnel would rely on the manual calculations, and
the EOF does not.use " SPECTER" it is apparent that the licensee's
capability for assessing the consequences of a primary to secondary
source term is limited.
The licensee was unable to produce documentation such as user guides
that would describe the codes methodologies, assumptions,.
- capabilities and limitations.
I
Several key individuals (those expected to use the codes,.i.e. a
Radiological Assessment Coordinator and a UDAC Dose Assessment
I
Coordinator) interviewed were not aware of all the capabilities
.
contained in the codes. The lack of awareness of-computer code
'
capabilities or existence indicates that training has not been given
)
in all cases when codes were'added or revised.

.
The licensee's failure to provide procedures to calculate doses from a
primary to secondary system-source term (except for the TSC) represents
an apparent violation of Technical Specification 6.8.1.e for failure to
maintain procedures.
One apparent violation for failure to maintain procedures pursuant to
Technical Specification 6.8.1.e (with multiple examples) was identified
in this program area.
6.
NO"IFICATIONS AND COMMUNICATIONS
Yhe inspector reviewed AP 506, " Notification /Co munication" to determine
that adequate provisions exist for notifying both offsite agencies and
District personnel of an emergency event. This included a review of AP 506.01, " Activation of the TSC", and AP 506.02, " Activation of the EOF".
In addition, the inspector had discussions with one individual from
security. This individual would be tasked with making notifications to
activate the TSC during the evening and backshift hours.
The inspector determined that the licensee has the capability, by
procedure, to notify all appropriate personnel and agencies. However the
discussion with the individual from security further substantiated
weaknesses in the area of training. The individual indicated that it had
been more than a year since emergency plan training had been provided,
and he was unable to locate the proper procedure for notifying District
personnel to activate the TSC. The individual was also unaware of proper
record keeping procedures. AP 506.01 requires records of names of
individuals contacted and the time of contact for planning purposes.
No violations were identified in this program area.
7.
LICENSEE AUDITS
10 CFR 50.54(t) requires licensees to provide for a review of the
emergency preparedness program by persons who have no direct
responsibility for implementation of the emergency preparedness program.
A review of the 1986 annual EP audit was performed. From this review the
audit appears to satisfy the regulatory requirements contained in 10 CFR 50.54(t). An examination of the 1985 annual EP audit (audit 0-692) was
also performed to ascertain the status of items identified as deficient
during 1985. Emergency Preparedness Audit number 0-692, the 1985 annual
EP audit, identified deficiencies in the Training Program, maintenance of
the Emergency Plan and implementing procedures, and the licensee's system
for maintaining required records (Plaza 50 Files). The findings of audit
0-692 were transmitted to Corporate and Plant management by letter dated
March 22, 1985. The findings of this inspection and the licensee's 1986
annual EP audit indicate that major deficiencies exist in the Training
Program, maintenance of the Emergency Plan and implementing procedures,
and the licensee's record system. It appears that the licensee has been
ineffective in correcting identified deficiencies (86-14-03).
There were no violations observed in this area.
8.
EMERGENCY DETECTION AND CLASSIFICATION
.
9
.
.
.
This program area was inspected to determine whether the licensee used
and understood the standard emergency classification and action level
scheme. Selected emergency action levels (EALs) specified in the
classification procedures were reviewed. The reviewed EALs appeared to
be consistent with the initiating events specified in Appendix 1 of
NUREG-0654. The inspector noted that some of the EALs were based on
parameters obtainable from Control Room instrumentation.
Interviews were held with two Shift Supervisors and two Senior Control
Room Operators to verify that they understood their responsibility and
authority in relation to accident classification, notification, and
protective action recommendations. Walk-through evaluations involving
accident classification problems were conducted vilu,these personnel.
The following weaknesses were identified:
(1) All personnel exhibited difficulty in using the EPIPs to classify
the hypothetical accident situation presented to them.
It was
necessary for them to search several times through the procedures to
locate desired information.
(2) The individuals were unable to locate in the procedures the person
responsible for assembly / accountability at the assembly area.
The inspector attributed the above weaknesses to the poor quality of the
licensee's training program as discussed in paragraph 3 above and in NRC
Inspection Report 50-312/86-06, paragraph 4.b.
To insure that the licensee's EALs are consistent with those of the state
and local agencies, discussions with those agencies were held.
10 CFR 50, Appendix E Section IV.B states in part, "That emergency action levels
shall be based on in plant conditions and instrumentation in addition to
onsite and offsite monitoring. These emergency action levels shall be
discussed and agreed on by the applicant and State and local governmental
authorities and approved by NRC. They shall also be reviewed with State
and local governmental authorities on an annual basis."
The discussions with state and local agencies indicated that a review of
the EALs had not taken place in 1985.
In addition, the licensee was
unsure if such a review had taken place and was unable to provide
documentation that such a review had been accomplished.
One apparent violation of 10 CFR 50, Appendix E Section IV.B was
identified in this program area for failure to provide for state and
local governmental review of EAL's (86-14-04).

PROTECTIVE ACTION DECISION-MAKING
This area was inspected to determine whether the licensee had a
24-hour-per-day capability to assess and analyze emergency conditions and
make recommendations to protect the public and onsite workers.

(a) Lack of guidance in the procedures for a protective action
recommendation based upon plant conditions.
(b) General impediments in the dose assessment area.
(c) Training deficiencies affecting the performance of key individuals.
The capability of offsite officials to make protective action decisions
and to promptly notify the public was discussed with licensee
representatives. Licensee procedures made provisions for contacting
responsible offsite authorities on a 24-hour basis. Backup
communications links with offsite authorities were available.
There were no violations identified in this program area.

EXIT INTERVIEW
An exit interview was held on April 25, 1985, for the purpose of
discussing the praliminary findings of this inspection. Licensee
personnel present have been previously identified in paragraph 1 above.
G. Perez, acting Senior Resident Inspector was also present. The
licensee was informed that violations were identified in a number of
program areas, and that NRC Management would determine the specific
course of action to be taken. The following observations were made by
the inspector:
1.
Training was deficient for numerous personnel in the onsite
organization, and the licensee's EP training program and
implementing procedure for training were not current.
2.
The Emergency Plan and implementing procedures were not being
maintained. District Personnel were also aware of this fact, This
may have an adverse effect on their effectiveness during an
emergency.
3.
The dose assessment program appeared marginal in several areas.
4.
The licensee had been ineffective in correcting problems previously
identified by the NRC and their own audit program of the emergency
preparedness program.
5.
The licensee does not have the capability to use their procedures to
determine a protective action recommendation based on plant
conditions.
