appears that this is a satisfactory alternative to operation on a

'

continuous basis.

O f. [6] (Ciosed) improvement Item (50-369/85-29-07, 50-370/85-28-07):

Using a different technique to alert control room operators that core

temperature is outside of the expected range. Inspection disclosed

l that a program was implemented to provide a different method for

alerting operators that core temperature is outside of the expected

range. The technique uses Core Exit Themoccuples (CET's) for range

checks within the temperature regime of 32 F - 2300 F. An offnormil

l value is printed in red and thus indicates that the value is outsice

an assigned range. Based upon program modification, the subject itim

Changing the OAC terminal keyboards, positioned in a nearly vertical

orientation, to an ergonomically correct position to minimize

mis-keying. Inspection disclosed that existing mounting position of

the OAC terminal keyboards poses no significant impediment or delay

to access of desired data.

k. [11] (0 pen) Improvement Item (50-369/85-29-12, 50-370/87-28-12):

Providing procedures or instructions developed to describe the method

for obtaining monitoring data from the OAC in the TSC. Inspection

disclosed that the licensee developed procedure No. OP/0/B/6700/08 to

describe the method for obtaining monitoring o'ata from the OAC in the

TSC. Review of the procedure addresses only normal data stream

transmission via manually offloading the floppy disc from 0AC to VAC

computer. No reference was made to the subject of the original

finding.

Evaluating locations of the meteorological towers to determine the

quality of data, and the effects of the nearby warehouse buildings,

proximity of major plant structures, and uneven terrain in the area

on such data. Inspection disclosed that the licensee performed an

analysis based on statistical relationships to determine the

potential effects of warehouse buildings, major plant structures, and

uneven terrain on meteorological data at Catawba. The analysis

appeared to utilize acceptable statistical and analytical concepts.

The results of the comparative analysis were reported to the NRC,

Region 2, in a letter dated June 6,1986. It appears that the

structures affect winds from the northeast and southeast quadrants;

however, the degree of non-conformity for both wind direction and

wind speed appears to be within acceptable limits.  ;

n. [14] (Closed) Improvement Item (50-369/85-29-16, 50-370/85-28-16):

Incorporating the meteorological measurements program, as updated in

National Weather Service (NWS) station at Charlotte Airport and/or

Catawba Station for real-time conditions at McGuire or installing of

backup or redundant onsite meteorological measurements, including

separate power supplies, cabling, and recorders. Inspection

consisted of a review of the licensee evaluation of the

representativeness of meteorological data from the National Weather

Service (NWS) station at the Charlotte Airport and/or Catawba for

real-time conditions at the McGuire facility. The evaluation

appeared to utilize acceptable statistical and analytical concepts.

The licensee arrived at the following conclusions from this study:

(1) wind direction data at Catawba Station or the NWS Charlotte

Airport yields distributions of direction differences with too much

scatter to reliably estimate wind direction at McGuire Station; (2)

wind Speed data from NWS Charlotte Airport yield wind speeds of half

that at Catawba Station, thus, Catawba wind speed equals twice the

NWS Charlotte Airport wind speed; (3) data from Catawba Station

yields an acceptable substitute for wind speed at McGuire Station;

(4) temperature difference: the NWS Charlotte Airport cannot provide

temperature difference data; (5) data at Catawba Station yields

distribution of temperature differences with too much scatter to

reliably estimate the temperature difference at McGuire.

This item will remain open pending resolution of the programs

compliance with guidance promulgated in Appendix 2 of NUREG-0654.

p. [16] (0 pen) Improvement Item (50-369/85-29-19, 50-370/85-28-19):

Revising procedures which provide for use of meteorological data to

reflect the hierarchy for data substitution, and specifying averaging

period (e.g., 15 minutes) and valid time of the observations.

Inspection disclosed that the licensee revised

Procedures HP/0/B/1009/08 and HP/0/8/1009/09 to identify the

hierarchy for meteorological data substitution and specified the

averaging period. The hierarchy established is not consistent with

the findings of the study performed by the licensee in response to

Item L15] above. For example, the revised procedures required that

if the wind speed at the McGuire Station is not available, the data

should be obtained from the NWS, Charlotte Airport. However, the

study concluded that the wind speed at the Charlotte Airport is not a

suitable substitute for McGuire Station. This item will remain open

until this discrepancy is resolved,

q. [17] (Closed) Improvement Item (50-369/85-29-20, 50-370/85-28-20):

Specifying averaging period and valid time of observation for digital

displays of meteorological data (e.g., via the OAC of the summary

sheet provided through the VAX computer). The inspector reviewed a

printout of the McGuire OAC Secondary System and observed that

averaging period is being provided.

r. [18] (Closed) Improvement Item (50-369/85-29-22, 50-370/85-28-22):

O Identifying of regional and forecast meteorological information to be

'd provided on request by the NWS Station in Charlotte. The licensee

maintains a staff of professional meteorologists and routinely

receives meteorological data from NOAA. It appears that the

licensee's expertise in this field permits its staff to adequately

provide regional and forecast meteorological data during an

emergency.

s. [19] (0 pen) Improvement Item (50-369/85-29-24, 50-370/85-28-24):

Modifying the Dose Assessment Class A Model to include ingestion

pathway dose calculations and making available to the NRC or

submitting to the NRC documentation related thereto. Inspection

disclosed that the licensee completed its investigation of

conmercially available dose assessment models. A final decision to

include the capability to calculate ingestion pathway doses has not

been made.

t. [20] (Closed) Improvement Item (50-369/85-29-26, 50-370/85-28-26):

Evaluating the Nuclear-23 method to assure that both whole body and

thyroid doses are appropriately considered in protective action

recommendations. Inspection disclosed that the licensee evaluated

the Nuclear-23 method to ensure that both whole body and thyroid

doses are appropriately considered in protective action

recommendations. The evaluation technique and results were

documented.

O u. c21] (Ciosed) improvement item (50-389/85-29-27, 50-370/85-28-27):

Making the " Nuclear-23" available for periodic use during exercises

to assure control room personnel proficiency in use of the program.

Licensee representatives stated that use of " Nuclear-23" is prevented

by interlock or relay until such time that an emergency occurs.

Inspection disclosed that the " Nuclear-23" dose assessment program

was available to Control Room personnel during simulator training,

v. [22] (0 pen) Improvement Item (50-369/85-29-28, 50-370/85-28-28):

Providing an uninterrupted power supply for all necessary components

of the data acquisition and display system (e.g., the VAX computer,

the dose assessment terminal, the Mohawk data link, etc.).

Inspection of the current status of power source to data acquisition

and data transmission systems disclosed that no changes were made

since the appraisal. This item remains open,

w. [23] (Closed) Improvement Item (50-369/85-29-29, 50-370/85-28-29):

Verifying that the Crisis Management Center (CMC) does not exercise

priority to the VAX; thus requiring the Station to conduct manual

calculation of dose assessments. Inspection disclosed that dose

assessment programs may be run in parallel on the VAX by both the TSC

and the CMC. The limitation is that only one user (the TSC or CMC)

may release an on-line report. This may be a desirable situation,

dependent upon whether the TSC or CMC has responsibility for

assessment.
