Persons Contacted
During the course .of this inspection the following personnel were
contacted.or interviewed:
- R. Knight, Licensing Engineer, TMI-I
- J. Whitehead, Emergency Planner
- G. Baker, Manager - Environmental Controls
- B. Good, Radiological Programs Manager
- J. Byrne, Manager, TMI-2 Licensing

2.
Purpose
The purpose of this inspection was to verify the licensee's completion of
various open items identified in previous inspections and to determine the
status of those items yet to be completed.
3.
Status of Previously Identified Items
3.1 (0 pen) Inspector Follow-up Item (289/83-20-03):
Evaluation of the
effect of a temperature increase on the response of the RM-L-10
turbine building sump radiation monitor.
Since the licensee has not /et qualified or quantified the effect of
temperature on the monitoring device, efforts were initiated to re-
view the operating procedure and reduce the alarm set point suf-
ficiently to offset instrument abnormalities that may be due to sump
temperature.
The licensee committed to complete the action by
December 15, 1984.
Further, the licensee committed to collect and
analyze sump temperature data for six months following plant start-up
to verify that sump temperatures did not exceed the instrument's per-
formance specifications. This item will remain open until sufficient
information is available to conclude that the instrument will perform
acceptably in the normal turbine sump environment.
3.2 (0 pen)
Inspector
Follow-up
Item
(289/84-03-01):
Provide
the
capability to obtain an RCS sample under all accident conditions and
modes of operation.
The licensee is in the process of completing system modification to
permit sampling from the Decay Heat System. Modifications were ex-
pected to be completed by November 17, 1984, followed by pre-opera-
tional and start-up testing in the following six weeks.

will remain open until the start-up testing program for the modifi-
cation has been successfully completed.

3.3 (Closed) Inspector Follow-up Item (289/84-03-02): Modify Containment
Atmosphere Sampling (CAS) System to permit sampling after containment
--
--
isolation; evaluate sample representativeness and make provisions to
assure that temperature and pressure corrections are considered.
EPIP 1004.31, " Post Accident Atmospheric Sampling" has been revised
to
address
design
changes
in
the
System
and
includes
consideration of temperature and pressure in the evaluation of sample
results. The CAS system has been modified to enable the acquisition
of a more reliable and representative sample.
The licensee has
verified system operability.
Override capability is provided to
enable sample acquisition if required following automatic containment
isolation. This item is considered closed.
3.4 (Closed) Inspector Follow-up Item (289/84-03-05): Provide results of
demonstration of chemical. analysis capability for chloride, boron and
pH using the intended post accident instrumentation and procedures.
The licensee's submittal dated February 29, 1984 provided the results
of a demonstration of ability to analyze a post accident standard
test matrix solution.
While most chemical parameter results were
acceptable, it was identified that the use of the Flouroborate
Specific Ion Electrode technique, Procedure CP-N1904.1, provided
unacceptably high errors for boron concentrations greater than 500
ppm.
In order to assure acceptable results, the licensee's program
now relies on the Mannitol Boron technique, Procedure CP-N1904, for
concentrations greater than 500 ppm.
Procedure CP-N1901.1 is only
used for concentrations less than 500 ppm boron.
Additionally, the licensee's Emergency Plan Implementing Procedure
1004.33, Revision 7, " Post Accident Sample Analysis", now addresses
the analysis of fission gases stripped from the coolant sample and
incorporates the information into the core damage estimation.
No. 494, Revision 2, " Post Accident Sampling Radiological Analysis",
addresses the personnel exposure due to acquisition of the stripped
gas sample.
This item is considered closed.
3.5 (0 pen) Inspector Follow-up Item (289/84-16-01):
Test and balance
Auxiliary and Fuel Handling Building Ventilation upon completion of
system modifications.
System modifications are not expected to be completed until April 1,
1985.
This item will remain open until test and balance data has
been reviewed.

3.6L(Closed) Inspector Follow-up Item (289/84-16-02):
Review process
control procedure to assure that the requirements of 10 CFR 61.55 and
61.56 are sufficiently addressed.
It was verified that Procedures 1104-28A and 1104-28I are both being
implemented and subject to-audit by the quality assurance ' group.
Quality Assurance Monitoring Reports Nos. SLS-0335-84, DMW-288-84,'
SJH-1015-84, DHW-308-84 and SCD-1254-84 were reviewed and substan-
tiate that the requireme'nts of 10 CFR 61.55 and 61.56 are being
'
implemented in the process control program.
-3.7
(Closed) Inspector Follow-up Item (289/84-16-03):
Review licensee's
response to IE Report 50-320/84-04 relative to ALARA effectiveness.
This item is closed with respect to Unit-1. The licensee's response
will be evaluated relative to Unit-2 ALARA effectiveness.
3.8 (Closed) Inspector Follow-up Item (289/84-03-07): Develop procedures
for the collection of representative plant effluent samples including
provisions for handling and analyzing high dose rate samples.
In order to reduce dose effect on personnel, the licensee modified
the existing MAP-5 system by not initially loading Channel #1 with
charcoal and particulate filters.
Following confirmation of the
extent of activity from the fractional collectors (channels #2 and
- 3), it will be determined if Channel #1 may be used as the primary
sample collector.
Applicable
procedures,
such
as
1004.31
" Post
Accident
Atmospheric Sampling", and associated N1990 Chemistry procedures have
been revised as necessary to accommodate the acquisition and analysis
of the sample.
Special sample geometrics have been established for
counting equipment and the capability has been established for pulse
pile-up rejection (PUR) circuits in the associated MCAs.
The PUR
circuit permits high count rate pulses to be resolved with correction
to dead time, and minimal increase in the counting error. This item
is considered closed.

tor summarized the purpose and scope of the inspection and identified
findings as described in this report.
.
At no time during the inspection was written material provided to the
licensee by the inspectors.
