- 043 Debris Cleanup KIRUNU (CLARA) ISLAND CLEANUP Kirunu has a surface area of 7 acres and wasthe site of one large and several lesser scientific stations used during Operation Ivy. It was nota site for any nuclear events. Vegetation was reasonably dense. Hazardous debris included one concrete bunker, a derelict crane, and a small amount of metal debris. There were an estimated 112 cubic yards of noncontaminated debris to be removed and three Master Index items. The planned use for Kirunu wasfood gathering.49 Debris cleanup began on 26 April 1978 and was completed on 9 June 1978. Five hundred and five cubic yards of noncontaminated debris were removed.>9 ELELERON (RUBY) ISLAND CLEANUP Eleleron’s physical configuration was altered so radically by test activities as to cause conflicting identifications of the island, even within the same report. As shown in Figure 5-19, the original island was almost as large as Lojwa (Ursula). The majority of the island, its entire center, was vaporized in two nucleartests, the George shot in Operation Greenhouse and the Mohawk shot in Operation Redwing. This left a 4-acre island which was identified by the Enewetak Radiological Survey and Volume I of the Engineering Survey as Ruby and by the JTG as Ruby’s Child or Ruby’s Daughter (code name Xeno). It also left two segments connected to Aomon by a narrow causeway which was bordered on the lagoon side by a marsh. The marsh wasfilled with soil during preparations for the Pacific Cratering Experiment (PACE)in 1972, joining the two southeast segments of Eleleron to Aomon in a peninsula which now appears to be part of Aomon. This peninsula was identified as Eleleron in Volume II of the Engineering Study, in the Master Index, and in most of the JTG reports. All of the cleanup work described in this section took place on the peninsula. No cleanup was required on the other remnant of Eleleron.5!.52.53 The Enewetak Radiological Survey regardedtheisland as a possible burial site because of the two ground zeros; however, bothsites are now underwater. Hazardous debris included 196 cubic yards of contaminated bulkhead rails, coaxial cables, and other metal scrap. Ten Master Index items were identified on the peninsula. The planned use for the island was food gathering.°4 Debris cleanup began on | June 1978 and, by 8 July 1978, generally was completed except for small amounts of yellow and green debris.°5 These were removed on 10 July 1978 and dumpedin the lagoon from a LARC.*6
