Meeting Summary: The Enforcement Conference was held to discuss the findings of
Inspection Report 50-423/88-03. The topics discussed at the meeting dealt with
the root cau;e analysis and corrective actions for an overpressure transient that
occurred at low temperature without the required overpressure protection systems
being in service. Additional topics were discussed, including generic implications
of the event and predicted plant response without operator action.

2. Purpose
The Enforcement Conference was initiated by NRC Region I to discuss the Janu-
ary 19, 1988 overpressure event without the required overpressure protection
systems operable. Northeast Nuclear Energy Company was requested to identify
and describe the event's root cause; broader implications; generic concerns;
lessons learned; and, both their short and long term corrective actions. To
ensure that the licensee was aware of the specific NRC concerns, Attachment
1 to this report hsd previously been provided to the licensee during the
February 18, 1988 exit meeting for Special Inspection 50-423/88-03,
3. Discussion
NRC management made a few brief opening remarks. NNECo then made a presenta-
tion based on the outline included as Attachment 2. NNECo agreed that the
events and technical issues described in the NRC January 18-29, 1988 special
inspection report were accurate.

During the RHR isolation event on January 19, a potentially significant event !
existed when the operating charging pump continued to run after the established
RHR letdown path was secured. Operator actions at the time were prompt and
appropriate. A relief valve on the letdown line downstream of the orifices
with a setpoint of 600 psig was capable of relieving RCS pressure during the
RHR isolation. The engineering evaluation discussed above demonstrates that
adequate margins remained to the reactor vessel limits. Although the RHR
isolation and RCS pressure increase event on January 19 is a significant event
that highlighted weaknesses in operating procedures, operator and technician
knowledge, drawings, and controls, the actual safety impact of the event was
minimal.
One item that warrants further licensee and NRC staff consideration because
of the potential significance of the isolation event is the question of "what
would the outcome of the transient have been if the operators had not acted
to mitigate the pressure increase." This question was presented to the lic-
ensee for consideration in his evaluation of the event.
8.0 Summary of Findings
Listed below are some issues to be discussed by the NRC and the licensee at
an enforcement conference. .
--
Evaluation of what the January 19th pressure transient outcome would have !
been assuming no operator action.
-
t
--
Adequacy of drawings and of training personnel in their use, especially
in interrelationships between drawings from dif ferent suppliers (e.g. ,
architect-engineer and NSSS vendor drawings).
--
Assuring that work affecting SSPS and other safety-related equipment is
performed by personnel having appropriate training, qualifications, and ,
experience.
<
--
Adequacy of controls allowing work on turbine bypass control circuits '
1
without tags for pulling fuses, and the duty senior control room operator .
on January 19th approving work without reviewing the applicable AWO. )
--
Adequacy and utility of Technical Specification curves prescribing
pressure-temperature limits.
--
Adequacy of procedures and training on the COPS design and interface with I
the SSPS. )
--
Use of alarn response procedures in post-transient reviews.
--
Appropriateness of provisions that allow up to 31 days to elapse between
surveilling a system for operability and placing it in operation, and
assuring adequacy of supporting equipment configuration in the interim
and afterwards,

--
Adequacy of the surveillance used to determine COP 3 operability.
--
Lack of positive indication of COPS arming. l

--
Development of a specific low temperature overpressure protection proce-
dure, or providing additional guidance in existing procedures to assure {
l
that operators are properly aware of low pressure overprotection fea-
tures' status and that they follow-up quickly, appropriately, and fully
to transients and to losses of overpressure protection.
--
Assumption by the operators that COPS was the available overpressure
system when, in fact, it was not operable. This resulted in the viola-
tion of TS 3.4.9.3 which requires at least one overpressure system to
be available at all times when less than 350 degress F (VIO 88-03-02).
The failure to notify the NRC about the overpressure transient via the
--
Emergency Notification System (ENS) within four hours (VIO 88-03-03).

EVENT SUMMARY .
:
On January 19,1988 with the plant solid in cold shutdown,
temperature 135 *F, pressure 350 psia, a pressure transient
occurred which challenged the COLD Overpressure Protection
System (COPS). COPS failed to operate when required. The
pressure transient was mitigated by manual operator action.

CONCERNS
- Pressure transient outcome assuming no operator action.
- Adequacy of drawings and of training personnel in their use.
- Work on safety related equipment performed by trained...
- Adequacy of controls of work.
- Adequacy of curves prescribing pressure temperature limits.
- Procedures / training on the COPS design / interface with SSPS.
- Surveillance interval / equipment configuration control.
- Are procedures inadequate to insure COPS operability?...
- Development of a specific low temperature overpressure...
- Use of alarm response procedures in post transient reviews.

The first capsule (Capsule U) should be removed at the end of the first core cycle (1st
refueling) as shown in Table 41. Subsequent capsules should be removed at 5,9, and 15
EFPY (Effective Full Power Years) as indicated. Each specimen capsule, removed after
exposure, will be transferred to a postirradiation test facility for disassembly and testing
of all the specimens.

criterion is satisfied throughout the event: ,750

(a) For isothermal pressure transients (i e., AT/At ' I h E "* ' N O T E "' **' ** t* " ***"'d'

the allowable salues of Table L1 at any value of

the design pressure and T, - RTuris not less than 'ALUATION BY ANALYSIS

CONCLUSIONS
O PRESSURE TRANSIENT OF JANUARY 19 HAS NO IMPACT ON
MILLSTONE 3 STRUCTURAL INTEGRITY.
O CHEMISTRY AND FLUENCE LIMIT RANGE OF ISOTHERMAL
TRANSIENTS OF CONCERN ~ 1500 F OR LESS.
0 OPERATIONAL LIMITS HAVE SIGNIFICANT SAFETY MARGINS
TO PRECLUDE COMPONENT DAMAGE.
