ENCI.0SURE: SEABROOK EMERGENCY PLAN EAl. EVALUATION A.
GENERAL FINDINGS:
1.
Figure 5.3, Critical Safety Function (CSF) for the Heat Sink, is j
improperly labeled Number 4 It should be Number H.
2.
The plan skips misc. emergency condition 8c, a typo.
3.
The words "other than fire" should be deleted from chart EAL 17 B.
PLAN EALS VS NUREG-0654 App. 1 GUIDANCE.
Note - In the remainder of this enclosure, paragraph numbers conform to the initiating conditions of Appendix 1 of NUREG-0654 NOTIFICATION OF UNUSUAL EVENT (NOVE) 1, 3c, 4, 5, 6, 9, and 17 are not specifically identified in the Seabrook EAls. Confirm that these initiating conditions are covered in the Seabrook tech specs and that a NOUE would be declared under such conditions.
3b. Classified as an Alert (not NOVE) at Seabrook but only if based upon letdown monitor readings. The case of equivalent values from an RCS sample (as distinct.from the letdown monitorl is not covered.
11 & 12.
Not covered by the Seabrook EAls.
8.
Not covered.
It appears that the intent was to cover this requirement in Seabrook EAL item 20.
Powever, no classification can result from item 20.
13, 14 & 15. Covered generically as Seabrook item 18a. However, the detailed definition stated in the NUREG initiating conditions is missing.
Seabrook simply discusses " hazards", undefined.
AI.ERT lb. The Seabrook EAL is solely contingent on letdown monitor and neglects the possibility of a 300 uti/cc input from an RCS sample, as is provided for in the more general definition of the NUREG.
Ic, 4, 6, 19.
Not covered in Seabrook EAI.s 5.
Incomplete.
Provided that the numbers work out, it possible that a leak of 50 GPM outside containment would invoke Seabrook EAL 12b.
- However, the case of-the 50 GPM leak inside containment is not addressed.
f O
. 10.
Incomplete. Although the Seabrook EAls address some facets of this item (e.g., 6c,16c, etc.I, it does not appear that " Complete loss of any function needed for plant cold shutdown" has been covered. Those functions must first be defined.
12.
Incomplete.
The Seabrook EAI. (13) states " fuel accident with release of radioactivity".
Recommend consider adding "to containment or fuel handling building".
15.
Incomplete.
Typically there are many tech spec radiological limits with one set called " instantaneous". Assuming that is the case, since no particular tech specs are referenced in Seabrook EAL 12b, omission of
" instantaneous" is critical.
16, 17 & 18.
Incomplete.
I.acking a definition of the word hazard in Seabrook 18b, it does not appear that the specific circumstances of the NUREG (II. D. 11 are covered by this item.
See comment under NOUE 13, 14, 15.
SITE AREA EMERGENCY (SAE) 1.
This initiating condition correlates to Seabrook EAL iten 15. However, there is no SAE in Seabrook 15.
The terminology " emergency coolant recirculation" is ambiguous.
5, 13a, 13b.
Not covered in Seabrook EAls.
8.
Clarification is needed. Many of the applicable situations are covered.
To ensure that " Complete loss of any function..." was addressed, definition of functions needed for hot shutdown is required.
- 10. Not covered by Seabrook EAls. Without input from radiation levels,.
the only classification made for a fuel handling accident by the Seabrook plan is an Alert.
The NUREG merely requires that the fire compromise the function of safety systems.
Seabrook's alert level (16b) fire is con-trolled, contained, and potentially affecting; the SAE fire is uncontrolled, uncontained, actually affecting.
There is no classification for a con-trolled, contained fire affecting safety related equipment consistent with NUREG-0654 The entire set of fire classifications in the plan should be reviewed.
- 14. Clarification of Seabrook EAL 18c is required with regard to " hazards" being defined to include " imminent loss of physical control of the plant".
l l
l
Clarification is required with regard to incorpor-ating the specific detail of the NUREG (e.g., flood, tornado, etc.) into
" hazards" in 18c.
GENERAL EMERGENCY (GE)
- 1. Incomplete. The aspects of 5 rem /hr thyroid, projected vs. actual, and actual meteorological conditions are not contained in Seabrook's plan EAL 12d.
Sa-Se. The plan relies upon the symptomatic process to encompass all of the circumstances listed in NUREG-0654 Appendix 1, GE PWR Sa-e, as it event-ually would. Powever, pending red or orange paths and the GE classification which establish the C orange /H red condition for GE, the reactor vessel would have to steam down to an abnormal RVLIS level and all steam generators would have to drop below a certain low value. As another example, the C orange /Z red GE condition is not met until containment pressure exceeds 52 psig.
It does not make sense to wait. The use of event related EAls should be considered rather than relying upon -the symptomatic process to lead to classification.
7.
Not covered by the Seabrook EAls.
